V$SORT_USAGEとV$SQLとV$SESSIONの連結SQLで.重複したデータを出力させないようにする方法

下記SQL文でV$SORT_USAGEとV$SQLとV$SESSIONをJOINした結果を表示させようと思いますが、
SESSION_ADDRが重複して出力されてしまいます。
重複を排除したSQL文を出力させる方法をわかる方いましたら、教えてください。
※本来は、SELECTするカラムはもっと多いですが、ここでは省力しています。
SELECT
     SORT.SESSION_ADDR
FROM
     V$SESSION SES,
     V$SORT_USAGE SORT,
     V$SQL SQL
WHERE
     SES.SADDR=SORT.SESSION_ADDR AND
     SES.SQL_ID=SQL.SQL_ID AND
     SES.SQL_CHILD_NUMBER = SQL.CHILD_NUMBER AND
     SES.SQL_ADDRESS=SQL.ADDRESS AND
     SORT.SQLADDR=SQL.ADDRESS AND
     SORT.SQLHASH=SQL.HASH_VALUE
ORDER BY
     BLOCKS;
SESSION_ADDR

00000003FC7C9258
00000003FF79BCF0
00000003FC7C9258
6 rows selected.
【備考】
・表示するカラムにV$SORT_USAGE.SQL_FULLTEXT(CLOB)も含めたい為、distinct句で
重複を排除する事ができません。
・DBはOracle10gです。

すみません。上記は自己解決しました。
※SEGMENT_TYPE別にSQL文が出力されるのですね

  • Setting security context in sql*plus session

    Hi,
    For a SQL*Plus session under an account that doesn't have execute privileges on fnd_global, is there any way to set the application security context similar to the way fnd_global.apps_initialize does?
    For example, as APPS one can do this:
    <br>
    sqlplus apps/...
    SQL>  select SYS_CONTEXT('FND','USER_ID' ) as fnd_user_id from dual;
    FND_USER_ID
    1 row selected.
    SQL> execute fnd_global.apps_initialize( ... );
    SQL> select SYS_CONTEXT('FND','USER_ID' ) as fnd_user_id from dual;
    FND_USER_ID
    123456
    1 row selected.What I'd like to do is something like this ...
    <br>
    sqlplus scott/...
    SQL> ... call some EBizSuite procedure where I can supply or
    be prompted for an EBizSuite user name, password, and responsibility ...
    SQL> select SYS_CONTEXT('FND','USER_ID' ) as fnd_user_id from dual;
    FND_USER_ID
    123456
    1 row selected.

    Hi
    Is there any method to initialize the environment using Java API.
    how to call the function fnd_global.apps_initialize
    Can you explain the required parameters.

  • SQL Plus session - "schema.package" has been invalidated on making any chng

    Hi
    I am in the process of testing a stored procedure. Whenever I make changes to the procedure I am executing it from the SQL Plus session. But whenever I make a change to the procedure - i have to close that particular SQL Plus session and open another one. I get the message:
    ORA-06510: PL/SQL: unhandled user-defined exception
    ORA-04061: existing state of has been invalidated
    ORA-04061: existing state of package body
    "schema.package" has been invalidated
    ORA-04065: not executed, altered or dropped package body
    Is there a way that I do not have to open a new SQL Plus session everytime I make change to the package?

    It does not help :(. I get this problem in a SQL+ session only when I make a change in a JDev session. I have to log off the SQL+ session and log back in and it is OK again without re-compling anything. I don't have a problem with two SQL+ session. Isn't that strange?

  • WCF-SQL Adapter and idle SQL Server sessions

    Hi,
    I have a BizTalk 2013 server with a send port that periodically send SQL statements to a remote SQL Server. The remote SQL Server hosts the database of a Dynamics NAV server.
    The DBA of this SQL Server warned me that a lot of SQL Server sessions remain idle after a long period of time (about 20 idle sessions coming from my BizTalk server with a Idle time that is more than 10 days). He thinks that we have a trouble in BizTalk to
    close the connections to the SQL Server.
    I wondered if I can handle the situation by changing some settings in the sqlBinding used by my send port, for example the MaxPoolSize or other parameters.
    Any idea?
    Thanks.

    So, is this causing an actual problem or is this something the DBA just happened to see?
    20 idle sessions isn't a lot at all and is well below the default Connection Pool size, 100 in most cases.
    So long as it does not keep increasing unchecked, I'd say what you're seeing is the expected and desired behavior.
    You maybe have had a burst at some point causing 20 connections, then normal continuous operations only uses 1 or 2.

  • How to Initiate Multiple SQL*Loader Sessions

    Oracle db utilities(Chapter-Conventional and Direct Path Loads) talks of parallel data loading models for direct load.
    We need to execute the following commands:
    sqlldr USERID=scott/tiger CONTROL=load1.ctl DIRECT=TRUE PARALLEL=true
    sqlldr USERID=scott/tiger CONTROL=load2.ctl DIRECT=TRUE PARALLEL=true
    sqlldr USERID=scott/tiger CONTROL=load3.ctl DIRECT=TRUE PARALLEL=true
    The previous commands must be executed in separate sessions, or if permitted on operating system, as separate background jobs.
    We want to run these in separate sessions. Our problem is that we have a job running which invokes sqlldr. Now how can we initiate Multiple SQL*Loader Sessions(actually multiple sql sessions which run concurrently,i.e. in parallel)? I need the command for it!
    Regds,
    Rohit

    I tried opening two files but selecting and hitting enter. it opens one SSMS and two tabs.

  • SQL*NET SESSION의 DEAD CONNECTION 처리 방법

    제품 : SQL*NET
    작성날짜 : 1996-04-03
    SQL*NET SESSION의 DEAD CONNECTION 처리 방법
    ==========================================
    server에서 수행 중이던 프로그램이 비정상 종료한 경우에는 오라클의 smon이
    자동으로 detection하여 수행 중이던 transaction을 rollback하여
    정리하여 준다.
    그러나, Client Server 환경에서 PC를 Client로 사용 시 비정상적인 방법으로
    Server와 Disconnect 하면 Server 쪽에 있는 Dedicated Server가 남아 있다.
    이는 Sql*net V1 & V2에서 발생하던 문제로 Sql*net V2.1 이후에는 아래와
    같은 방법을 이용하면 Dead connection이 정상적으로 Disconnect 된다.
    * 환경 : Server - Sql*net tcp/ip V2.1.3
    Client - Sql*net V2.0
    * Setup 방법 : Server와 Client에 있는
    $ORACLE_HOME/network/admin/sqlnet.ora에
    sqlnet.expire_time=n
    으로 setting 한다.
    여기서 n은 분 단위이며 실제 disconnect는 n분보다 더 걸린다.
    일반적으로 sqlnet.expire_time=1로 설정하면 적당하다.

    Hi,
    Probe send - client and application still there - all fine
    Network cable on the client is removedAt the above stage if the Sever sents a probe then if does not receive any message from Client it is treated as DCD. (It will receive any error code or negative response from client instead of any active status communication)
    Application is shut down
    (Optionally the computer is rebooted)
    Network cable is reattached
    Next probe send from server
    At this point, the client is reachable, the Oracle NET component on the client is there, but the application on the client is gone without properly saying good bye to the DB server.
    Would DCD detect the dead connection in this sceanrio?If my above comment is dismissed and your case or assumptions continues, then we need to check the SQL_EXPIRE time which you have connected. If the every thing happens with in the time setted for Expire time then, still it will treat as DCD, your session is getting terminated the system got rebooted.
    You understanding with DCD is correct.
    We see sessions in V$SESSIONS that don't have a process on the client any more. We have SQLNET.EXPIRE_TIME set to 2 minutes on the server, but still these sessions show up after days. Sessions show up as inactive and are waiting on "SQL*NET message from client" for hours and days.See basically INACTIVE and DCD are different. Slight difference exits. As you said you find inactive sessions. If you want to cleanup those inactive sessions, as per oracle documenation, you can create a custom profile as per your requrement and assign some IDLE_TIME and update the respective user profile. That might help you out.

  • How to block Sql Plus sessions in Oracle 10g

    Hi,
    I want to block all sql plus sessions in oracle 10g, as we have a application and we need each and every one to use this application not the sql plus session.
    Kindly update us as soon as possible. and also thanks in advanced.

    Understand the concept Karl, but a layered defense seldom works in the IP world. If I manage to get through the firewall, then how can you prevent me access, at IP level, at any other ISO stack layer? If you manage to get through, then your firewall policies could just be too weak :) at least you must have some kind of an IDS infrastructure in place..
    what I mean is, you can have infinite number of threats.. and this will be part of your Risk Analysis. Determining all possible threats to the assets, what are being protected and their associated value, and predicting the rate of occurrence.... with all of these you could probably come up with contingency plans and incident response.. And most of all, you should not ignore the fact that people are creative, ingenious, and curious, and they'll prove this to you by testing your security implementations. So you'll have to periodically evaluate your security.. that's why there are audits.. Also, you must balance Security, Performance, Usability, and your Budget.
    Yes, you can argue that if the entire firewall goes down (thus no IP defense), then something like DBV (or even denying IPs in sqlnet) can provide some defense. But is that not then a case of too little too late? It's better too little too late, than no protection at all... Imagine if there's no DBV, or if you have not implemented the concept of "Least Privilege"? or if the backups and exports are not encrypted? That would be more devastating.. that's the importance of database security options and features in providing "defense in depth"
    I question just what purpose and how effective IP packet security is at higher layers. It can never substitute doing this instead at firewall level. Well, it's not all about network security. All facets must be considered and the inter-relationships should be understand. Like the core information security and access management, physical and personnel security, training them, etc... And all of these are equally important in providing a secure ecosystem
    As for security that relies on the client to pass secure data (like executable name or o/s user name)... all this can easily be spoofed. Even if the app and Oracle driver are somehow digitally signed and these signatures can be verified on the server side, we only need to look at Vista to see how secure this really would be. Microsoft attempted to encrypt every single h/w and s/w layer from the physical DVD track to the pixel on the monitor.. and this was defeated. And this was done as o/s kernel level. It is less complex to hack at driver level and even trivial to do it at application level.Security is about risk management. Blocking SQL*Plus does not negate the risk of SQL from the wild being run on a production server. For example, the client is a VB client using ODBC. It is easy to create a proxy that accepts the ODBC connection from the VB client and proxy the OCI packets to the real Oracle server. Now you have a man-in-the-middle than can inspect every single SQL call made to Oracle, and inject any PL/SQL or SQL code it wants.
    Security is far beyond writing a login trigger to deny SQL*Plus sessions and calling that a defense. >
    Yes I agree with you. That's why there are independent organizations and regulating bodies that provides security best practices, to give us a headstart on comming up of strong security policies.
    And one of my favorites is the one provided by IASE (sponsored by Defense Information Systems Agency) where there's lot of content regarding hardening and policies

  • DBMS_SYSTEM : 다른 USER나 SESSION에 SQL TRACE 걸기

    제품 : SQL*PLUS
    작성날짜 : 2002-04-12
    DBMS_SYSTEM : 다른 USER나 SESSION에 SQL TRACE 걸기
    ==================================================
    Purpose
    DBA user등에서 일반 user가 실행하는 sql의 trace를 떠 보고 싶은
    경우가 있다. 이렇게 다른 user session에 sql trace를 받을 수 있는
    방법에 대해 알아보자.
    Explanation
    SQL*Plus에 접속하여 SQL trace를 거는 것이 아니라 DBMS_SYSTEM package를
    이용하여 다른 유저나 다른 세션에서 특정 세션을 지정하여 SQL trace를 걸
    수 있다.
    ( DBMS_SYSTEM package는 Oracle 7.3부터 사용할 수 있다. )
    DBMS_SYSTEM package를 사용하기 위해서는 먼저 다음의 script를 실행한다.
    $ cd $ORACLE_HOME/rdbms/admin
    $ sqlplus sys/manager
    SQL> @dbmsutil
    SQL> @prvtutil.plb
    dbmsutil.sql file은 sys user나 svrmgrl 에서 실행시킨다.
    이 package를 다른 유저에서 실행하려면 미리 grant를 주어야 한다.
    $ sqlplus sys/manager
    SQL> grant execute on dbms_system to system;
    [ DBMS_SYSTEM package ]
    - DBMS_SYSTEM.set_sql_trace_in_session(sid, serial#, TRUE)
    지정된 session에 대해 SQL trace를 실행하여 user_dump_dest parameter에
    지정된 위치에 trace file이 생성된다.
    - DBMS_SYSTEM.set_sql_trace_in_session(sid, serial#, FALSE)
    지정된 session에 대한 SQL trace를 해제한다.
    Example
    system user에서 scott user를 지정하여 SQL trace를 건다.
    sqlplus system/manager
    SQL> select sid, serial#
    from v$session
    where username = 'SCOTT';
    SID SERIAL#
    8 12
    SQL> exec sys.dbms_system.set_sql_trace_in_session(8, 12, TRUE);
    -> scott user에 대한 SQL trace가 실행된다.
    SQL> exec sys.dbms_system.set_sql_trace_in_session(8, 12, FALSE);
    -> scott user에 걸린 SQL trace가 해제된다.
    참고 :
    Dedicate 방식으로 접속한 user는 user_dump_dest/ora_processid.trc로
    생기며, MTS 방식으로 접속한 user에 대해서는
    background_dump_dest/s000_22509.trc 와 같이 MTS server name으로
    생성된다.
    또한, 위 경우 모두 trace file을 한번 삭제한 후에 다시 그 process를
    사용하는 session에 대해 trace를 걸면 trace file은 생기지 않는다.

  • Unable to use PL/SQL Debugger, Production SQL Developer on OS X 10.4

    I am still unable to use the PL/SQL debugger in OS X.
    When I start the debugger I get this:
    Connecting to the database testdb.
    Executing PL/SQL: ALTER SESSION SET PLSQL_DEBUG=TRUE
    Executing PL/SQL: ALTER SESSION SET PLSQL_COMPILER_FLAGS=INTERPRETED
    Executing PL/SQL: CALL DBMS_DEBUG_JDWP.CONNECT_TCP( '172.16.81.33', '49260' )
    Debugger accepted connection from database on port 49260.
    Processing 56 classes that have already been prepared...
    Finished processing prepared classes.
    Then nothing, it never gets to a breakpoint or does anything else. It works just fine on my Win XP box, just not on my OS X machine.
    Anyone having this problem or have any tips to try? I've never gotten the debugging to work on any Raptor or SQL Developer build in OS X. However, JDeveloper debugging works just fine on this mac.

    I am also experiencing this problem.
    Perhaps the following excerpt from the console can shed some light on the problem.

  • 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;
    the output like,
    SAL (TO_CHAR(TO_DATE(SAL,'J'),'JSP'))
    800 eight hundred
    1600 one thousand six hundred
    1250 one thousand two hundred fifty
    If you want to add some text like, Rs. Three Thousand only.
    SQL> select sal "Salary ",
    (' Rs. '|| (to_char(to_date(sal,'j'), 'Jsp'))|| ' only.'))
    "Sal in Words" from emp
    Salary Sal in Words
    800 Rs. Eight Hundred only.
    1600 Rs. One Thousand Six Hundred only.
    1250 Rs. One Thousand Two Hundred Fifty only.
    43 Display Odd/ Even number of records
    Odd number of records:
    select * from emp where (rowid,1) in (select rowid, mod(rownum,2) from emp);
    Output:-
    1
    3
    5
    Even number of records:
    select * from emp where (rowid,0) in (select rowid, mod(rownum,2) from emp)
    Output:-
    2
    4
    6
    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
    Doesn't have selective features (where clause) Has
    Doesn't fire database triggers Does
    It requires disabling of referential constraints. Does not require

    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.

    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?

    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.

    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.

    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.

  • Dynamic SQL within a SQL Query ?

    is there any possibility to do like this ?
    SELECT table_name, XXXXXXXX('SELECT Count(*) FROM '||table_name) tot_rows
      FROM dba_tables
    WHERE owner = 'SCOTT';or any other trick to run dynamic SQL within the SQL Query?
    Hoping....that it should be.
    Regards,
    Orapdev

    One small disadvantage: it is executing 202 SQL statements: 3 "user SQL statements" (the one above and the 2 "select count(*)..."), and 199 internal ones ...How did you get to those numbers?
    I just traced this statement and found completely different results:

  • DB buffer cache vs. SQL query & PL/SQL function result cache

    Hi all,
    Started preparing for OCA cert. just myself using McGraw Hill's exam guide. Have a question about memory structures.
    Actually, DB buffer cache is used to copy e.g. SELECT queries result data blocks, that can be reused by another session (server process).
    There is also additional otion - SQL query & PL/SQL function result cache (from 11g), where also stored the results of such queries.
    Do they do the same thing or nevertheless there is some difference, different purpose?
    thanks in advance...

    There is also additional otion - SQL query & PL/SQL function result cache (from 11g), where also stored the results of such queries.Result cache located in shared pool.So it is one component of shared pool.When server process execute query(and if you configured result cache) then result will store in shared pool.Then next execution time run time mechanism will detect and consider using result cache without executing this query(if data was not changed this is happen detection time)
    Do they do the same thing or nevertheless there is some difference, different purpose?.Buffer cache and result cache are different things and purpose also,but result cache introduced to improve response time of query in 11g(but such mechanism also implemented in 10g subquery execution,in complex query).In buffer cache holds data blocks but not such results.

  • Debugging a PL/SQL with Oracle SQL Developer

    I am trying to debug pl in Oracle SQL Developer, have looked in
    http://www.oracle.com/technology/obe/11gr2_db_prod/appdev/sqldev/plsql_debug/plsql_debug_otn.htm#t5
    and there are not enabled the options "Data", "Smart Data", etc someone knows why?
    thank you.

    In the log windows, when debug, show tihis:

    Ejecutando PL/SQL: ALTER SESSION SET PLSQL_DEBUG=TRUE
    Ejecutando PL/SQL: CALL DBMS_DEBUG_JDWP.CONNECT_TCP( '10.240.193.202', '2310' )
    Later, 1 min.
    show this
    ORA-30683: failure establishing connection to debugger
    ORA-12535: TNS:operation timed out

    El proceso ha terminado.

    so, do you think, the problem is a firewal, i can´t verify this.
