(Oracle 8 and 9) UTF16 char stream and OCIStmtPrepare

Hi,
I am using Oracle 8.1.7 on windows (should soon use Oracle 9.2) and Oracle 10g on MacosX.
I have an UTF16 strings in buffers containing SQL commands (like Create tables, or insert, ...) . some of the string contains some real weird characters (such as euro currency sign).
I want to call OCIStmtPrepare then OCIStmtExecute, like I do usually with basic ascii C-strings.
My concern is that I cannot figure out what is expected in the CONST text * argument of OCIStmtPrepare, I mean how should I encode the sql commands to have it accept the command ?
Does anybody know what is the encoding that we are supposed to provide with Oracle 8.1.7 and Oracle 9.2? is there any parameter somewhere ?
Thanks for your help.

Hi,
Thanks, but this is not of a great help.
I am not speaking about type casting (I also discovered that text is actually a unsigned char type), nu my concern is about encoding
Within unsigned char string, you can encode the same string differently : take the e acute char, it wont be encoded the same way in utf8, in iso-8859-1, etc...
Just take a look at the "Character encoding" of your web browser, if it is a modern one like Firefox, and you'll where my concen is.
thanks for answering,

  • Data transfer problem between Oracle 9 and Oracle 8

    We have two enviroments one in oracle 9 and other is oracle 8, both are on different unix servers.
    There is a DBlink for Oracle 8 on the oracle 9 database. Now when we try to select any data from oracle 9 and insert into oracle 8 using the dblink all the VARCHAR or CHAR values are going as null.
    For example if we try the following sql:
    INSERT INTO oracle8table@dblink (col1_varchar,col2_num)
    SELECT col1_varchar,col2_num FROM oracle9table
    all the col1_varchar are populated as NULL, however the col2_num is getting populated correctly.
    The data type of both the columns are identical.
    Any help on this highly appreciated.
    Thanks

    How about posting the table structures just to make your post more clearer and avoid ambiguity ?
    Just a matter of thought it is always better to pull the data rather than push the data. For e.g. in oracle you cannot use direct path insert while pushing the data but you can use direct path insert while pulling data.

  • Oracle 11g and PRO*C :  pre-compile errors only with 11g !

    Hi !
    I didn't find a forum specific to pro*c, so here i am.
    I've downloaded Oracle 11g and recompiled our applications using pro*c
    We currently precompiling without any problem our sources against Oracle 7, 8, 9, 10.
    With Oracle 11g, it doesn't work !
    every EXEC SQL followed by a command works.
    every EXEC SQL followed by a query generates the same error.
    Example :
    char *oracle_date_courante()
         static char buf[SIZE_ORADATE+1];
         EXEC SQL SELECT sysdate into :buf from DUAL;
         if(ORA_SQLERROR())
              oracle_error("sélection date courante");
              buf[0]=0;
         return buf;
    PRO*C output :
    Erreur Ó la ligne 105, colonne 2 dans le fichier src\oracle.pc
    EXEC SQL
    .1
    PLS-S-00000, SQL Statement ignored
    erreur sÚmantique Ó la ligne 105, colonne 2, fichier src\oracle.pc:
    EXEC SQL
    .1
    PCC-S-02346, PL/SQL a trouvÚ des erreurs sÚmantiques
    So, we investigated... And found that thoses errors come when we use the option sqlcheck=semantics.
    If we use an inferiour check level, it works but because we use PL/SQL keywords, pro*c prints errors and wants us to provide the 'semantics' sqlcheck level !
    So, it's a vicious circle !
    Any ideas ?
    Thanks...
    Vincent

    Adding the option common_parser=yes removes the errors !
    But brings errors linked to the PL/SQL parser such like
    CSF-S-00000, ORA-06544: PL/SQL : erreur interne, arguments : [55916], [], [], []
    1>, [], [], [], []
    1>ORA-06553: PLS-801: erreur interne [55916]
    Really vicious..and still not precompiling !
    By the way : Server is 10.2.0.1... and i guess thoses errors are normal since the common parser is not available in this version...
    So bye bye option common_parser and i'm back to my orignals errors.

  • Replication between Oracle Server and MS SQL Server

    Hello,
    Does anybody know of a well known or reliable software that can do data replication between Oracle Server and Microsoft SQL server.
    I suppose I can write my own version using Heterogenous Services in Oracle but I would like to know if such an automated replication between Oracle and SQL is available commercially.
    Thank you.

It could be very interesting.Sorry Viacheslav, even I couldn't find anything for the same. I am not sure that it can be done or not, I haven't heard anyone in my contact doing so. The only place where I have seen Streams being used around me is within Oracle db only. May be someone else can help if he/she has done it.

  • Data Guard with Oracle 9i and 10g -- have you done it?

    We have an ERP system (JDEdwards, db size approx 600 GB) and we'd like to copy the data in this system to a database on another computer. We'd use the remote database for reporting, so we need it to be available. We are looking at using Data Guard running in Logical Standby mode.
    The ERP database is Oracle 9i, and we are considering having the Logical Standby database be 10g. Have you done this and if so, what was your experience?
    Here's why we want to do this. There are many tables in the ERP database that contain descending indexes. We can't change this, and it is not supported with Data Guard under Oracle 9.2. Tables with descending indexes do not copy to the logical standby database.
    We were told that this is corrected in a newer release of Oracle, and we were wondering if a 10g database would properly copy tables with descending indexes.
    Thanks in advance for any experiences you can share.
    Best Regards,
    Mike

    What you are trying to do might not be possible. Because when you create logical standby you have to create a physical standby first and convert it. Primary and standby have to be same version.
    In furture it might be possible because 10G will support rolling upgrade of logical standby.
    However even it's possible you have to go through a lot of pain to setup and maintain it because Oracle don't support the setup.
    What you could try are Stream and Replication, I will say Stream is very interesting one. Because Oracle say : "Oracle Streams and Oracle Data Guard (including Data Guard SQL Apply) are independent features based on some common underlying infrastructure and technology. "

  • Oracle SQL and PL/SQL interview questions.

    Can anyone forward me all Oracle SQL and PL/SQL Interview questions and answers asap.
    Many Thanks.
    Bba

    Dear Pal
    I not sure all the all answers are correct. I got one mail couple yrs back. I am just sharing mail contents. Kindly keep question and compare answers.
    1 Which is more faster - IN or EXISTS?
    EXISTS is more faster than IN because EXISTS returns a Boolean value whereas IN returns a value.
    2 Which datatype is used for storing graphics and images?
    LONG RAW data type is used for storing BLOB's (binary large objects).
    3 When do you use WHERE clause and when do you use HAVING clause?
    HAVING clause is used when you want to specify a condition for a group function and it is written after GROUP BY clause. The WHERE clause is used when you want to specify a condition for columns, single row functions except group functions and it is written before GROUP BY clause if it is used.
    4 What WHERE CURRENT OF clause does in a cursor?
    LOOPSELECT num_credits INTO v_numcredits FROM classesWHERE dept=123 and course=101;UPDATE studentsSET current_credits=current_credits+v_numcreditsWHERE CURRENT OF X;END LOOPCOMMIT;END;
    5 What should be the return type for a cursor variable.Can we use a scalar data type as return type?
    The return type for a cursor must be a record type.It can be declared explicitly as a user-defined or %ROWTYPE can be used. eg TYPE t_studentsref IS REF CURSOR RETURN students%ROWTYPE
    6 What is use of a cursor variable? How it is defined?
    A cursor variable is associated with different statements at run time, which can hold different values at run time. Static cursors can only be associated with one run time query. A cursor variable is reference type (like a pointer in C).Declaring a cursor variable:TYPE type_name IS REF CURSOR RETURN return_type type_name is the name of the reference type,return_type is a record type indicating the types of the select list that will eventually be returned by the cursor variable.
    7 What is the purpose of a cluster?
    Oracle does not allow a user to specifically locate tables, since that is a part of the function of the RDBMS. However, for the purpose of increasing performance, oracle allows a developer to create a CLUSTER. A CLUSTER provides a means for storing data from different tables together for faster retrieval than if the table placement were left to the RDBMS.
    8 What is the maximum buffer size that can be specified using the DBMS_OUTPUT.ENABLE function?
    1,000,00
    9 What is syntax for dropping a procedure and a function .Are these operations possible?
    Drop Procedure procedure_nameDrop Function function_name
    10 What is OCI. What are its uses?
    Oracle Call Interface is a method of accesing database from a 3GL program. Uses--No precompiler is required,PL/SQL blocks are executed like other DML statements. The OCI library provides· -functions to parse SQL statemets· -bind input variables· -bind output variables· -execute statements· -fetch the results
    11 What is difference between UNIQUE and PRIMARY KEY constraints?
    A table can have only one PRIMARY KEY whereas there can be any number of UNIQUE keys. The columns that compose PK are automatically define NOT NULL, whereas a column that compose a UNIQUE is not automatically defined to be mandatory must also specify the column is NOT NULL.
    12 What is difference between SUBSTR and INSTR?
    SUBSTR returns a specified portion of a string eg SUBSTR('BCDEF',4) output BCDEINSTR provides character position in which a pattern is found in a string. eg INSTR('ABC-DC-F','-',2) output 7 (2nd occurence of '-')
    13 What is difference between SQL and SQL*PLUS?
    SQL*PLUS is a command line tool where as SQL and PL/SQL language interface and reporting tool. Its a command line tool that allows user to type SQL commands to be executed directly against an Oracle database. SQL is a language used to query the relational database(DML,DCL,DDL). SQL*PLUS commands are used to format query result, Set options, Edit SQL commands and PL/SQL.
    14 What is difference between Rename and Alias?
    Rename is a permanent name given to a table or column whereas Alias is a temporary name given to a table or column which do not exist once the SQL statement is executed.
    15 What is difference between a formal and an actual parameter?
    The variables declared in the procedure and which are passed, as arguments are called actual, the parameters in the procedure declaration. Actual parameters contain the values that are passed to a procedure and receive results. Formal parameters are the placeholders for the values of actual parameters
    16 What is an UTL_FILE.What are different procedures and functions associated with it?
    UTL_FILE is a package that adds the ability to read and write to operating system files. Procedures associated with it are FCLOSE, FCLOSE_ALL and 5 procedures to output data to a file PUT, PUT_LINE, NEW_LINE, PUTF, FFLUSH.PUT, FFLUSH.PUT_LINE,FFLUSH.NEW_LINE. Functions associated with it are FOPEN, ISOPEN.
    17 What is a view ?
    A view is stored procedure based on one or more tables, it’s a virtual table.
    18 What is a pseudo column. Give some examples?
    It is a column that is not an actual column in the table.eg USER, UID, SYSDATE, ROWNUM, ROWID, NULL, AND LEVEL.
    19 What is a OUTER JOIN?
    Outer Join--Its a join condition used where you can query all the rows of one of the tables in the join condition even though they don’t satisfy the join condition.
    20 What is a cursor?
    Oracle uses work area to execute SQL statements and store processing information PL/SQL construct called a cursor lets you name a work area and access its stored information A cursor is a mechanism used to fetch more than one row in a Pl/SQl block.
    21 What is a cursor for loop?
    Cursor For Loop is a loop where oracle implicitly declares a loop variable, the loop index that of the same record type as the cursor's record.
    22 What are various privileges that a user can grant to another user?
    · SELECT· CONNECT· RESOURCES
    23 What are various constraints used in SQL?
    · NULL· NOT NULL· CHECK· DEFAULT
    24 What are ORACLE PRECOMPILERS?
    Using ORACLE PRECOMPILERS, SQL statements and PL/SQL blocks can be contained inside 3GL programs written in C,C++,COBOL,PASCAL, FORTRAN,PL/1 AND ADA.The Precompilers are known as Pro*C,Pro*Cobol,...This form of PL/SQL is known as embedded pl/sql,the language in which pl/sql is embedded is known as the host language. The prcompiler translates the embedded SQL and pl/sql ststements into calls to the precompiler runtime library.The output must be compiled and linked with this library to creater an executable.
    25 What are different Oracle database objects?
    · TABLES· VIEWS· INDEXES· SYNONYMS· SEQUENCES· TABLESPACES etc
    26 What are different modes of parameters used in functions and procedures?
    · IN· OUT· INOUT
    27 What are cursor attributes?
    · %ROWCOUNT· %NOTFOUND· %FOUND· %ISOPEN
    28 What a SELECT FOR UPDATE cursor represent. [ANSWER]SELECT......FROM......FOR......UPDATE[OF column-reference][NOWAIT] The processing done in a fetch loop modifies the rows that have been retrieved by the cursor. A convenient way of modifying the rows is done by a method with two parts: the FOR UPDATE clause in the cursor declaration, WHERE CURRENT OF CLAUSE in an UPDATE or declaration statement.
    29 There is a string 120000 12 0 .125 , how you will find the position of the decimal place?
    INSTR('120000 12 0 .125',1,'.')output 13
    30 There is a % sign in one field of a column. What will be the query to find it?
    '' Should be used before '%'.
    31 Suppose a customer table is having different columns like customer no, payments.What will be the query to select top three max payments?
    SELECT customer_no, payments from customer C1
    WHERE 3<=(SELECT COUNT(*) from customer C2
    WHERE C1.payment <= C2.payment)
    32 minvalue.sql Select the Nth lowest value from a table
    select level, min('col_name') from my_table where level = '&n' connect by prior ('col_name') <
    'col_name')
    group by level;
    Example:
    Given a table called emp with the following columns:
    -- id number
    -- name varchar2(20)
    -- sal number
    -- For the second lowest salary:
    -- select level, min(sal) from emp
    -- where level=2
    -- connect by prior sal < sal
    -- group by level
    33 maxvalue.sql Select the Nth Highest value from a table
    select level, max('col_name') from my_table where level = '&n' connect by prior ('col_name') >
    'col_name')
    group by level;
    Example:
    Given a table called emp with the following columns:
    -- id number
    -- name varchar2(20)
    -- sal number
    -- For the second highest salary:
    -- select level, max(sal) from emp
    -- where level=2
    -- connect by prior sal > sal
    -- group by level
    34 How you will avoid your query from using indexes?
    SELECT * FROM emp
    Where emp_no+' '=12345;
    i.e you have to concatenate the column name with space within codes in the where condition.
    SELECT /*+ FULL(a) */ ename, emp_no from emp
    where emp_no=1234;
    i.e using HINTS
    35 How you will avoid duplicating records in a query?
    By using DISTINCT
    36 How you were passing cursor variables in PL/SQL 2.2?
    In PL/SQL 2.2 cursor variables cannot be declared in a package.This is because the storage for a cursor variable has to be allocated using Pro*C or OCI with version 2.2, the only means of passing a cursor variable to a PL/SQL block is via bind variable or a procedure parameter.
    37 How you open and close a cursor variable.Why it is required?
    OPEN cursor variable FOR SELECT...Statement
    CLOSE cursor variable In order to associate a cursor variable with a particular SELECT statement OPEN syntax is used. In order to free the resources used for the query CLOSE statement is used.
    38 How will you delete duplicating rows from a base table?
    delete from table_name where rowid not in (select max(rowid) from table group by duplicate_values_field_name); or
    delete duplicate_values_field_name dv from table_name ta where rowid <(select min(rowid) from table_name tb where ta.dv=tb.dv);
    39 How do you find the numbert of rows in a Table ?
    A bad answer is count them (SELECT COUNT(*) FROM table_name)
    A good answer is :-
    'By generating SQL to ANALYZE TABLE table_name COUNT STATISTICS by querying Oracle System Catalogues (e.g. USER_TABLES or ALL_TABLES).
    The best answer is to refer to the utility which Oracle released which makes it unnecessary to do ANALYZE TABLE for each Table individually.
    40 Find out nth highest salary from emp table
    SELECT DISTINCT (a.sal) FROM EMP A WHERE &N = (SELECT COUNT (DISTINCT (b.sal)) FROM EMP B WHERE a.sal<=b.sal);
    For Eg:-
    Enter value for n: 2
    SAL
    3700
    41 Display the records between two range?
    select rownum, empno, ename from emp where rowid in (select rowid from emp where rownum <=&upto minus select rowid from emp where rownum<&Start);
    42 Display the number value in Words?
    SQL> select sal, (to_char(to_date(sal,'j'), 'jsp'))
    from emp;

    44 Difference between procedure and function.
    Functions are named PL/SQL blocks that return a value and can be called with arguments procedure a named block that can be called with parameter. A procedure all is a PL/SQL statement by itself, while a Function call is called as part of an expression.
    45 Difference between NO DATA FOUND and %NOTFOUND
    NO DATA FOUND is an exception raised only for the SELECT....INTO statements when the where clause of the querydoes not match any rows. When the where clause of the explicit cursor does not match any rows the %NOTFOUND attribute is set to TRUE instead.
    46 Difference between database triggers and form triggers?
    Data base trigger(DBT) fires when a DML operation is performed on a data base table. Form trigger(FT) Fires when user presses a key or navigates between fields on the screen
    Can be row level or statement level No distinction between row level and statement level.
    Can manipulate data stored in Oracle tables via SQL Can manipulate data in Oracle tables as well as variables in forms.
    Can be fired from any session executing the triggering DML statements. Can be fired only from the form that define the trigger.
    Can cause other database triggers to fire.Can cause other database triggers to fire, but not other form triggers.
    47 Difference between an implicit & an explicit cursor.
    PL/SQL declares a cursor implicitly for all SQL data manipulation statements, including quries that return only one row. However,queries that return more than one row you must declare an explicit cursor or use a cursor FOR loop.
    Explicit cursor is a cursor in which the cursor name is explicitly assigned to a SELECT statement via the CURSOR...IS statement. An implicit cursor is used for all SQL statements Declare, Open, Fetch, Close. An explicit cursors are used to process multirow SELECT statements An implicit cursor is used to process INSERT, UPDATE, DELETE and single row SELECT. .INTO statements.
    48 Can you use a commit statement within a database trigger?
    No.
    49 Can the default values be assigned to actual parameters?
    Yes
    50 Can cursor variables be stored in PL/SQL tables.If yes how. If not why?
    No, a cursor variable points a row which cannot be stored in a two-dimensional PL/SQL table.
    51 Can a primary key contain more than one columns?
    Yes
    52 Can a function take OUT parameters. If not why?
    No. A function has to return a value,an OUT parameter cannot return a value.
    53 What are various joins used while writing SUBQUERIES?
    Self join-Its a join foreign key of a table references the same table. Outer Join--Its a join condition used where One can query all the rows of one of the tables in the join condition even though they don't satisfy the join condition.
    Equi-join--Its a join condition that retrieves rows from one or more tables in which one or more columns in one table are equal to one or more columns in the second table.
    54 Differentiate between TRUNCATE and DELETE
    TRUNCATE deletes much faster than DELETE
    TRUNCATE
    DELETE
    It is a DDL statement It is a DML statement
    It is a one way trip,cannot ROLLBACK One can Rollback

    Programmatic Constructs
    Last Update: September 06, 2004
    1 What are the different types of PL/SQL program units that can be defined and stored in ORACLE database ?
    Procedures and Functions,Packages and Database Triggers.
    2 What are the differences between Database Trigger and Integrity constraints ?
    A declarative integrity constraint is a statement about the database that is always true. A constraint applies to existing data in the table and any statement that manipulates the table.
    A trigger does not apply to data loaded before the definition of the trigger, therefore, it does not guarantee all data in a table conforms to the rules established by an associated trigger.
    A trigger can be used to enforce transitional constraints where as a declarative integrity constraint cannot be used.
    3 What is difference between Procedures and Functions ?
    A Function returns a value to the caller where as a Procedure does not.
    4 What is Database Trigger ?
    A Database Trigger is procedure (set of SQL and PL/SQL statements) that is automatically executed as a result of an insert in,update to, or delete from a table.
    5 What is a Procedure ?
    A Procedure consist of a set of SQL and PL/SQL statements that are grouped together as a unit to solve a specific problem or perform a set of related tasks.
    6 What is a Package ?
    A Package is a collection of related procedures, functions, variables and other package constructs together as a unit in the database.
    7 What are the uses of Database Trigger ?
    Database triggers can be used to automatic data generation, audit data modifications, enforce complex Integrity constraints, and customize complex security authorizations.
    8 What are the advantages of having a Package ?
    Increased functionality (for example,global package variables can be declared and used by any proecdure in the package) and performance (for example all objects of the package are parsed compiled, and loaded into memory once)
    1 With which function of summary item is the compute at options required?
    percentage of total functions.
    2 Why is it preferable to create a fewer no. of queries in the data model?
    Because for each query, report has to open a separate cursor and has to rebind, execute and fetch data.
    3 Why is a Where clause faster than a group filter or a format trigger?
    Because, in a where clause the condition is applied during data retrieval than after retrieving the data.
    4 Which parameter can be used to set read level consistency across multiple queries?
    Read only.
    5 Which of the two views should objects according to possession?
    view by structure.
    6 Which of the above methods is the faster method?
    performing the calculation in the query is faster.
    7 Where is the external query executed at the client or the server?
    At the server.
    8 Where is a procedure return in an external pl/sql library executed at the client or at the server?
    At the client.
    9 When do you use data parameter type?
    When the value of a data parameter being passed to a called product is always the name of the record group defined in the current form. Data parameters are used to pass data to produts invoked with the run_product built-in subprogram.
    10 When a form is invoked with call_form, Does oracle forms issues a save point?
    Yes
    11 What are the important difference between property clause and visual attributes?
    Named visual attributes differ only font, color & pattern attributes, property clauses can contain this and any other properties. You can change the appearance of objects at run time by changing the named visual attributes programmatically , property clause assignments cannot be changed programmatically. When an object is inheriting from both a property clause and named visual attribute, the named visual attribute settings take precedence, and any visual attribute properties in the class are ignored.
    12 What use of command line parameter cmd file?
    It is a command line argument that allows you to specify a file that contain a set of arguments for r20run.
    13 What is WHEN-Database-record trigger?
    Fires when oracle forms first marks a record as an insert or an update. The trigger fires as soon as oracle forms determines through validation that the record should be processed by the next post or commit as an insert or update. c generally occurs only when the operators modifies the first item in the record, and after the operator attempts to navigate out of the item.
    14 What is use of term?
    The term file which key is correspond to which oracle report functions.
    15 What is trigger associated with the timer?
    When-timer-expired.
    16 What is the use of transactional triggers?
    Using transactional triggers we can control or modify the default functionality of the oracle forms.
    17 What is the use of place holder column?
    A placeholder column is used to hold calculated values at a specified place rather than allowing is to appear in the actual row where it has to appear.
    18 What is the use of image_zoom built-in?
    To manipulate images in image items.
    19 What is the use of hidden column?
    A hidden column is used to when a column has to embed into boilerplate text.
    20 What is the use of break group?
    A break group is used to display one record for one group ones. While multiple related records in other group can be displayed.
    21 What is the remove on exit property?
    For a modelless window, it determines whether oracle forms hides the window automatically when the operators navigates to an item in the another window.
    22 What is the purpose of the product order option in the column property sheet?
    To specify the order of individual group evaluation in a cross products.
    23 What is the maximum no of chars the parameter can store?
    The maximum no of chars the parameter can store is only valid for char parameters, which can be upto 64K. No parameters default to 23Bytes and Date parameter default to 7Bytes.
    24 What is the main diff. bet. Reports 2.0 & Reports 2.5?
    Report 2.5 is object oriented.
    25 What is the frame & repeating frame?
    A frame is a holder for a group of fields. A repeating frame is used to display a set of records when the no. of records that are to displayed is not known before.
    26 What is the difference between OLE Server & Ole Container?
    An Ole server application creates ole Objects that are embedded or linked in ole Containers ex. Ole servers are ms_word & ms_excel. OLE containers provide a place to store, display and manipulate objects that are created by ole server applications. Ex. oracle forms is an example of an ole Container.
    27 What is the difference between object embedding & linking in Oracle forms?
    In Oracle forms, Embedded objects become part of the form module, and linked objects are references from a form module to a linked source file.
    28 What is the difference between boiler plat images and image items?
    Boiler plate Images are static images (Either vector or bit map) that you import from the file system or database to use a graphical elements in your form, such as company logos and maps. Image items are special types of interface controls that store and display either vector or bitmap images. Like other items that store values, image items can be either base table items(items that relate directly to database columns) or control items. The definition of an image item is stored as part of the form module FMB and FMX files, but no image file is actually associated with an image item until the item is populate at run time.
    29 What is the difference between $$DATE$$ & $$DBDATE$$ $$DBDATE$$ retrieves the current database date $$date$$ retrieves the current operating system date.
    30 What is the diff. when Flex mode is mode on and when it is off?
    When flex mode is on, reports automatically resizes the parent when the child is resized.
    31 What is the diff. when confine mode is on and when it is off?
    When confine mode is on, an object cannot be moved outside its parent in the layout.
    32 What is the diff. bet. setting up of parameters in reports 2.0 reports 2.5?
    LOVs can be attached to parameters in the reports 2.5 parameter form.
    33 What is the advantage of the library?
    Libraries provide a convenient means of storing client-side program units and sharing them among multiple applications. Once you create a library, you can attach it to any other form, menu, or library modules. When you can call library program units from triggers menu items commands and user named routine, you write in the modules to which you have attach the library. When a library attaches another library, program units in the first library can reference program units in the attached library. Library support dynamic loading-that is library program units are loaded into an application only when needed. This can significantly reduce the run-time memory requirements of applications.
    34 What is term?
    The term is terminal definition file that describes the terminal form which you are using r20run.
    35 What is system.coordination_operation?
    It represents the coordination causing event that occur on the master block in master-detail relation.
    36 What is synchronize?
    It is a terminal screen with the internal state of the form. It updates the screen display to reflect the information that oracle forms has in its internal representation of the screen.
    37 What is strip sources generate options?
    Removes the source code from the library file and generates a library files that contains only pcode. The resulting file can be used for final deployment, but can not be subsequently edited in the designer. ex. f45gen module=old_lib.pll userid=scott/tiger strip_source YES output_file
    38 What is relation between the window and canvas views?
    Canvas views are the back ground objects on which you place the interface items (Text items), check boxes, radio groups etc.,) and boilerplate objects (boxes, lines, images etc.,) that operators interact with us they run your form . Each canvas views displayed in a window.
    39 What is pop list?
    The pop list style list item appears initially as a single field (similar to a text item field). When the operator selects the list icon, a list of available choices appears.
    40 What is new_form built-in?
    When one form invokes another form by executing new_form oracle form exits the first form and releases its memory before loading the new form calling new form completely replace the first with the second. If there are changes pending in the first form, the operator will be prompted to save them before the new form is loaded.
    41 What is lexical reference? How can it be created?
    Lexical reference is place_holder for text that can be embedded in a sql statements. A lexical reference can be created using & before the column or parameter name.
    42 What is forms_DDL?
    Issues dynamic Sql statements at run time, including server side pl/SQl and DDL
    43 What is difference between open_form and call_form?
    when one form invokes another form by executing open_form the first form remains displayed, and operators can navigate between the forms as desired. when one form invokes another form by executing call_form, the called form is modal with respect to the calling form. That is, any windows that belong to the calling form are disabled, and operators cannot navigate to them until they first exit the called form.
    44 What is bind reference and how can it be created?
    Bind reference are used to replace the single value in sql, pl/sql statements a bind reference can be created using a (:) before a column or a parameter name.
    45 What is an user exit used for?
    A way in which to pass control (and possibly arguments ) form Oracle report to another Oracle products of 3 GL and then return control ( and ) back to Oracle reports.
    46 What is an OLE?
    Object Linking & Embedding provides you with the capability to integrate objects from many Ms-Windows applications into a single compound document creating integrated applications enables you to use the features form .
    47 What is an object group?
    An object group is a container for a group of objects; you define an object group when you want to package related objects, so that you copy or reference them in other modules.
    48 What is an anchoring object & what is its use?
    An anchoring object is a print condition object which used to explicitly or implicitly anchor other objects to itself.
    49 What is a User_exit?
    Calls the user exit named in the user_exit_string. Invokes a 3Gl program by name which has been properly linked into your current oracle forms executable.
    50 What is a timer?
    Timer is an "internal time clock" that you can programmatically create to perform an action each time the timer expires.
    51 What is a Text_io Package?
    It allows you to read and write information to a file in the file system.
    52 What is a text list?
    The text list style list item appears as a rectangular box which displays the fixed number of values. When the text list contains values that can not be displayed, a vertical scroll bar appears, allowing the operator to view and select undisplayed values.
    53 What is a property clause?
    A property clause is a named object that contains a list of properties and their settings. Once you create a property clause you can base other object on it. An object based on a property can inherit the setting of any property in the clause that makes sense for that object.
    54 What is a physical page ? & What is a logical page ?
    A physical page is a size of a page. That is output by the printer. The logical page is the size of one page of the actual report as seen in the Previewer.
    55 What is a library?
    A library is a collection of subprograms including user named procedures, functions and packages.
    56 What is a difference between pre-select and pre-query?
    Fires during the execute query and count query processing after oracle forms constructs the select statement to be issued, but before the statement is actually issued. The pre-query trigger fires just before oracle forms issues the select statement to the database after the operator as define the example records by entering the query criteria in enter query mode. Pre-query trigger fires before pre-select trigger.
    57 What is a combo box?
    A combo box style list item combines the features found in list and text item. Unlike the pop list or the text list style list items, the combo box style list item will both display fixed values and accept one operator entered value.
    58 What does the term panel refer to with regard to pages?

  • BUG for sort column with Oracle 11g and APEX 3.2

    I have BUG in Report region(Oracle 11g and APEX 3.2). if i have more than 746 Char for my column's value and i want to sort them, this error appear
    Report error :
    ORA-00910: specified length too long for its datatype.
    But in an other environement in Oracle 10g and apex 3.2, with the same data. I have no BUG.
    Somebody have an idea for a possible solution to this problem???

    Again, I may just be wasting your time...but if I have XDB problems...especially with the password, I do the following:
    1. Change your working directory to $ORACLE_HOME/apex.
    2. Start SQL*Plus and connect to the database where Oracle Application Express is installed as SYS.
    3. Run apxconf.sql
    > @apxconf
    4. When prompted, enter a password for the Oracle Application Express Admin account.
    5. When prompted, enter the port for the Oracle XML DB HTTP server. (default port being, of course,8080).
    6. Unlock the ANONYMOUS account
    > ALTER USER ANONYMOUS ACCOUNT UNLOCK;
    7. If needed, I do the SETHTTPPORT command mentioned before...
    Since I'm using the Oracle 11g, with embedded PL/SQL server, I have no idea if this is the same for 10g us OHS?
    Hope that helps!

  • How to replicate data  between Oracle db and SQL server dbs in real time?

    Hello,
    Anyone has idea that what tool we can use to do data replication in real time between Oracle and SQL sever or Oracle and Sybase or Sql server and Sybase?
    This is topic is brought by a project manager?
    I only know Oracle to Oracle dbs by streams or GoldenGate.
    Thanks
    Jerry

    Since GoldenGate's bread and butter was (and is) replicating data between heterogeneous data sources, and since Oracle has purchased GoldenGate, that would seem like a natural place to start.
    Beyond that, it depends on the architecture you want and how you define "real time." Just about any ETL tool on the market, whether Oracle's ODI or OWB or any number of third party products (Informatica, DataStage, etc) can handle "trickle feeds" from various data sources to a database target of your choosing. Different tools will have different sorts of integration with the source database, many will require that a bunch of triggers are created to track changes on the source systems.
    If you want Oracle to control the replication process (which doesn't really make sense if we're talking about replication from a non-Oracle database to another non-Oracle database), you can use the Oracle Transparent Gateway products to create database links from Oracle to the non-Oracle databases and query data on the source database periodically.

  • Integrating Collaboration Suite, Oracle Portal and E-Business to SSO

    Hello,
    I am in the middle of integrating several Oracle applications and one non-Oracle application to an Identity Management fresh installation.
    I found the procedure to integrate E-Business to SSO, with bi-directional provisioning, but I am stuck with the integration of the next applications, Oracle Collaboration Suite and Oracle Portal:
    1. How to integrate them to my new SSO Server? is it enough with the ssoreg.sh script?
    2. What happens to the users? do I have to manually import them into my new SSO/OID install?
    3. What happens with new users? how do they get created? are they now created in the new SSO/OID server?
    If someone has had any experience with this kind of tasks, I will really appreciate your feedback. Thanks in advance.

    You might ask this question in the Streams forum. You might ask it in the e-Business Suite forum. You might ask it at metalink. But asking it here is not likely to get you the definitive answer you need. I would make sure, before I made such a business decision, I heard it directly from Oracle Support Services.

  • Oracle, Null and empty Strings

    Currently I'm facing problems with a class, which contains a String, which
    is set to "" (empty String).
    When the class is persistent, oracle writes null to the table column
    (which seems to be common oracle behaviour) and when retrieving the class,
    the field is set to null as well, giving me a lot of null-pointer
    exceptions.
    Anyway ... I can cope with that (just a lot of extra work)
    far worse is the problem, wenn searching objects, that have this field set
    to "" oder null.
    Oracle can't find the records because JDO creates Querys "where
    string=null" or "where string=''" , where oracle expects "where string is
    null" to find the records.
    Is there a workaround or solution ?

    Yeah, that would work as well, thx, but since I have to cope with
    null-Strings now everywhere in my program, it doesn't hurt just to forbid
    empty strings on the program side.
    In future times I'll test on Oracle first, then porting to DB/2 - this way
    I suppose work is far less to garant compability.
    Nevertheless ... having to set the bankcode into quotes is a kodo bug in
    my opinion.
    Kodo knows the type of classfields (in this case string) and shouldn't
    send the parameter as a BigDecimal to the database.
    Given that, and having only bankcodes of null (only neccesary when using
    Oracle), the method would look like:
    public Collection getAccounts (String bankCode)
    throws Exception
    return getAccounts (Account.class, "bankcode=="+bankcode);
    which is how a transparent persistent layer, um, should be , um , I mean
    ... just transparent ;-D
    Marc Prud'hommeaux wrote:
    Stefan-
    Couldn't you just do something like:
    public Collection getAccounts (String bankCode)
    throws Exception
    String filter;
    if (bankCode == null || bankCode.length () == 0)
    filter = "(bankCode == null || bankCode == "")";
    else
    filter = "bankCode == "" + bankCode + """;
    return getAccounts (Account.class, filter);
    If I understand the problem correctly, this should work for all the
    databases.
    In article <[email protected]>, Stefan wrote:
    What operations are you performing to cause this SQL to be issued? You
    say you are having trouble removing objects, but this is clearly not a
    DELETE statement. Is this the SQL that is issued when looking up

    A string column... is it also represented as a string field in your class?Yeah ... just to give you an impression of the code:
    First we have a class, representing a bank account:
    public class Account {
    private AccountMgr myAccountMgr;
    private String bankCode;
    private String id;
    Note, that in nearly all cases bankCode will be a number or null.
    I have a second class "AccountMgr", which does all of the persistant stuff
    (seaching, making persistent etc.)
    This class has two methods, one versatile (protected) to retrieve accounts
    by a given filterString and one who just returns accounts by bankCode,
    building the expected filterstring. Here is my current working version:
    public class AccountMgr {
    public Collection getAccounts(String bankCode) throws Exception {
    if (bankCode!=null) {
    if (bankCode.equals("")) {
    throw new Exception("check code, bankCode='' not allowed to get
    same behavior from DB2 and Oracle");
    // if set, quote the bankCode
    bankCode="""+bankCode+""";
    return getAccounts(Account.class,"bankCode=="+bankCode);
    protected Collection getAccounts(Class accountClass, String filterAdd)
    throws Exception {
    PersistenceManager pm = MyHelper.getPersistenceManager();
    String filter="";
    if (filterAdd!=null && !filterAdd.trim().equals("")) {
    filter+=filterAdd + " && ";
    filter += "myAccountMgr==_accMgr";
    Query query = pm.newQuery(accountClass, filter);
    query.declareParameters("AccountMgr _accMgr");
    return (Collection) query.execute(this);
    As you can see, in the first method I have to set the bankCode into
    quotes, when it's not null.
    This is because otherwise a filter like "bankCode=1234" will be translated
    in a way, where 1234 is send as a BigDecimal to the database:
    [...] executing statement <4239745>: (SELECT [...] FROM JDO_ACCOUNT t0
    WHERE t0.BANKCODE = ? : [reused=1;params={(BigDecimal) 1234}]

  • Select query differences between oracle 9 and oracle 8.

    Hi,
    I have a problem using the select query between oracle 7 and oracle 9i I don't have the same result :
    ex:
    With oracle7
    SQL> select 'champ1','champ2' from DUAL;
    'CHAMP 'CHAMP
    champ1 champ2
    With Oracle 9
    SQL> select 'champ1','champ2' from DUAL;
    'CHAMP1' 'CHAMP2'
    champ1 champ2
    So Can someone tell me how to solve this problem ? Is there a parameter in oracle 9 to set?
    Thanx.

    Whenever you are posting anything over internet forums like this - you should be very careful about not just posting the details which requires to solve the problem - also should be sensible about your question.
    This is not at all desired when you are posting such question. It may be because - you may not well aware of the fact.
    My suggestion is -> First Go through the basics Of SQL in general.
    Then go for any specific product like Oracle/ SQL Server/ Sybase etc.
    And, finally learn the advanced commands of that DB.
    You asked it - may be you thought the difference in output in terms of lines. But, that is not your actual output. That is the graphical display part only.
    Anyway,
    You can get the quite familier output by first type the following command ->

    What is the Diffrence between Oracle 11 and Oracle11i ?.
    With Rgds
    Arun J.Isaac

    Oracle 11i is internet based and run with java platform where we can see the applets downloading alongwith oracle forms and it refreshes all the jar files in oracle default directory.
    Oracle 11 is not intergrated with Java its an Oracle standalone platform.

    hi user ...
    on windows there are some steps in front of installation and configuration.
    1) cleare the Windows Env (Path .. Programme x86 )
         no Blank in Path and so on
    2) insert into your local host file your server and IP Adress
    3) in Windows 32 setup of WLS is JDK included so you don't have to install the jdk in front of WLS
    4) verify if you are using the right installation medium (jdk 32 bit, wls 32 bit , fmw 32 bit
    in your OraInventory/logs directory is a *.out file for your installation please can you put this file in the forum
    is there a nodemanager up and running (if so please stop)

  • Oracle Portal and Discoverer Integration

    Portal Version: 9.0.2.0.1
    RDBMS Versjion: 9.0.1.3
    OS/Vers. Where Portal is Installed:: Suse 7 SLES
    Error Number(s)::
    Oracle Portal and Discoverer Integration
    We're trying to integrate Discoverer with Portal unsuccessfully.
    We made many things in accordance with oracle's documentation until add discoverer portlets (worksheet and list of workbooks) in a test page.
    In view mode, the worksheet portlet shows the error:
    "The portlet has not been defined. The publisher must define the portlet by clicking on Edit Defaults for the portlet on the edit mode of this page. Please contact the publisher of this page."
    We think we have to edit properties before. Is this? Anyway edit worksheet portlet crashes between step 1 and 2. The error is: "The listener returned the following Message: 500 Internal Server Error".
    We have a public conection created in EM and a discoverer application which can be viewed using plus or viewer.
    Furthermore, it's not possible delete the added portlets neither the page that contain it. The error at delete is:
    Error: An unexpected error occurred: User-Defined Exception (WWC-44082)
    (WWC-00000)
    An unexpected error has occurred in portlet instances: User-Defined Exception (WWC-

    Edit properties for portlet List of Workbook works but in view mode we have the error in the portlet area:
    "Failed to refresh portlet. Please verify that the information used to create the
    portlet instance or customization is still valid. Otherwise, please contact your
    iAS administrator. oracle.discoiv.controller.FatalControllerException:
    DiscoNetworkException - Nested exception: org.omg.CORBA.OBJECT_NOT_EXIST: minor
    code: 0 completed: No null"
    Any ideas?
    Thanks

    Hi there,
    Have you applied any patches to 9ias since it was first installed? We had the same problem and had to apply a couple of patches to get the portlets working.
    1. Apply the 9.0.2.53.16 one-off patch for Oracle 9iAS Discoverer which takes Discoverer up to 9.0.2.53.16. This patch appears to be password protected and you need to get someone at Oracle support to give you a password.
    2. Apply the Discoverer Portlet Provider: 9.0.2.53.00c patch (patch no. 2595444) which gives you a new discportal.xsl file that actually works. It's this second step that solves your problem but you need to do step 1 before this. This is password protected as well.
    3. As you've upgraded Disco on the server to 9.0.2.53, you'll need to upgrade Disco Admin & Desktop within your 9iDS installation using patch no. 2555265. This is because Disco 9.0.2.53 uses an upgraded EUL that Disco Admin & Desktop need to be patched to use.
    This was the course of action Oracle support advised us about nine months ago. Of course they may have released a further patch to Disco that does 1 & 2 in one go, but we regularly carry out steps 1 and 2 on servers we use and we can use the Disco portlets successfully.
    Hope this helps
