PL/SQL and Oracle SQL Developer

I just downloaded the latest version of Oracle SQL Developer, because I heard that it is free and comes with a debugger.
So I have it all setup, I am connected to my database, but I wanted to execute a simple example:
I selected to create a new Procedure and a new tab opened up, I pasted this code and under DBMS Output, I clicked the + to: set serveroutput on
CREATE OR REPLACE PROCEDURE TEST1 As
DECLARE
   mytext varchar2(100) := 'Hello world!' ;
BEGIN
   dbms_output.put_line(mytext) ;
   dbms_output.put_line(mytext) ;
END TEST1;yet, I get an error:
Source does not have a runnable target.
So, is this made to only work with the database objects ? Tables ? I can't execute a simple Hello World ?
Please help, thanks!

I just want to make sure my dollars will not go there anymore...If you paid someone to use this forum you were robbed.

The responses you received accurately identified the problems you were having were a result of attempting to debug a procedure before you had compiled it. For free. And you complain.
Now that is rude.

What is Difference between ANSI SQL and ORACLE SQL

Hi,
I am going to take the assesment test for ANSI SQL Programming before that i want to know any difference between ANSI SQL and ORACLE SQL?
I am studying for SQL but the test will be ANSI SQL please let me give an idea about the both.
Thanks
Merina Roslin

Basically there is syntax difference between both of them.
Lets say i want to join two table EMP and DEPT based on DEPTNO.
With Oracle SQL format its like this.
select e.*
from emp e, dept d
where e.deptno = d.deptnoHere the joining condition goes in the WHERE clause.
With ANSI SQL format its like this.
select e.*
from emp e
join dept d
on e.deptno = d.deptnoHere the join condition is mentioned separately and not in WHERE clause.
Oracle supports ANSI SQL starting from 9i version.
You can read more about the syntax difference Here

Can i run all the SQL And PL/SQL in Oracle SQL Developer?

hi all
I have heard that Oracle Sql Developer is a free editor for Oracle DB from Oracle.
Is it possible to run all the the procedres and functions in that editor
is there any limitation for that ,can i run all the things that we can run on the SQL Plus
if anybody knows please let me know
thanks & regards

Interesting way of putting it.
When it comes to SQL and PL/SQL, SQLPlus and SQL Developer do not really 'run' very much.
Most of the time, these things are just shells that pass the SQL and PL/SQL requests to the appropriate engine (database) which will run the command.
The challenges are:
- will the shell interpret the request as something to pass to an engine?
- will the shell display the response from the engine appropriately?

Differences between TOAD for Oracle and Oracle SQL Developer?

Does someone know the advantages and disadvantages of using TOAD for Oracle and Oracle SQL Developer?
I work making reports with TOAD, but in a few days I will have to use the SQL Developer (because it´s free) unless I justify the necessity of using TOAD.
Could some that used both compare them?
Thanks,
Facundo.

Hello Facundo,
since we are rolling out new client PCs we switch from Toad to SQL Developer. Therefore I'm doing some training for the "normal" users and our developers.
Most users simply want to have access to the data in tables and views. For those there are 2 main issues:
- Filters get lost when exiting table while sorting is still applied. Since there is no way to apply filtering before entering the data tab this can become a great performance issue because sorting is applied to many many rows. For views it is sometimes impossible to open the data tab.
- Exporting date values to Excel needs some know how if you want to sort by this column in Excel, because the date is formatted as "Standard" meaning that the sorting is done as for a text column: 01.01.2009 is less than 02.01.2008. Here you have to use a workaround column with a formula (=1*<datecolumn>)
The greatest Pro is the easy sharing of connections and reports by XML files.
Our developers like the easy debugging in SQL Developer. Though they miss the feature that the source is compiled for debug automatically as in Toad. For this we have distributed a script that compiles any PL/SQL object for debugging.
There are only some Toads installed for DBAs and for users that need access to tables protected by policies that require authentification by OS user since this information is not passed under every circumstance.

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.

-- 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

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.

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

Database trigger is stored PL/SQL program unit associated with a specific database table. Usages are Audit data modifications, Log events transparently, Enforce complex business rules Derive column values automatically, Implement complex security authorizations. Maintain replicate tables.
17 What is a cursor for loop ?
Cursor for loop implicitly declares %ROWTYPE as loop index,opens a cursor, fetches rows of values from active set into fields in the record and closes
when all the records have been processed.
eg. FOR emp_rec IN C1 LOOP
salary_total := salary_total +emp_rec sal;
END LOOP;
18 What is a cursor ? Why Cursor is required ?
Cursor is a named private SQL area from where information can be accessed. Cursors are required to process rows individually for queries returning multiple rows.
19 What happens if a procedure that updates a column of table X is called in a database trigger of the same table ?
Mutation of table occurs.
20 What are two virtual tables available during database trigger execution ?
The table columns are referred as OLD.column_name and NEW.column_name.
For triggers related to INSERT only NEW.column_name values only available.
For triggers related to UPDATE only OLD.column_name NEW.column_name values only available.
For triggers related to DELETE only OLD.column_name values only available.
21 What are two parts of package ?
The two parts of package are PACKAGE SPECIFICATION & PACKAGE BODY.
Package Specification contains declarations that are global to the packages and local to the schema.
Package Body contains actual procedures and local declaration of the procedures and cursor declarations.
22 What are the two parts of a procedure ?
Procedure Specification and Procedure Body.
23 What are the return values of functions SQLCODE and SQLERRM ?
SQLCODE returns the latest code of the error that has occurred.
SQLERRM returns the relevant error message of the SQLCODE.
24 What are the PL/SQL Statements used in cursor processing ?
DECLARE CURSOR cursor name, OPEN cursor name, FETCH cursor name INTO or Record types, CLOSE cursor name.
25 What are the modes of parameters that can be passed to a procedure ?
IN,OUT,IN-OUT parameters.
26 What are the datatypes a available in PL/SQL ?
Some scalar data types such as NUMBER, VARCHAR2, DATE, CHAR, LONG, BOOLEAN.
Some composite data types such as RECORD & TABLE.
27 What are the cursor attributes used in PL/SQL ?
%ISOPEN - to check whether cursor is open or not
% ROWCOUNT - number of rows fetched/updated/deleted.
% FOUND - to check whether cursor has fetched any row. True if rows are fetched.
% NOT FOUND - to check whether cursor has fetched any row. True if no rows are featched.
These attributes are proceeded with SQL for Implicit Cursors and with Cursor name for Explicit Cursors.
28 What are the components of a PL/SQL Block ?
Declarative part, Executable part and Exception part.
Datatypes PL/SQL

A set of related declarations and procedural statements is called block.
30 What are advantages fo Stored Procedures /
Extensibility,Modularity, Reusability, Maintainability and one time compilation.
31 Name the tables where characteristics of Package, procedure and functions are stored ?
User_objects, User_Source and User_error.
32 Is it possible to use Transaction control Statements such a ROLLBACK or COMMIT in Database Trigger ? Why ?
It is not possible. As triggers are defined for each table, if you use COMMIT of ROLLBACK in a trigger, it affects logical transaction processing.
33 How packaged procedures and functions are called from the following?
a. Stored procedure or anonymous block
b. an application program such a PRC C, PRO COBOL
c. SQL *PLUS
a. PACKAGE NAME.PROCEDURE NAME (parameters);
variable := PACKAGE NAME.FUNCTION NAME (arguments);
EXEC SQL EXECUTE
b.
BEGIN
PACKAGE NAME.PROCEDURE NAME (parameters)

Insert Update Delete
Before Row o.k. o.k. o.k.
After Row o.k. o.k. o.k.
Before Statement o.k. o.k. o.k.
After Statement o.k. o.k. o.k.
If FOR EACH ROW clause is specified, then the trigger for each Row affected by the statement.

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?
A panel is the no. of physical pages needed to print one logical page.
59 What are visual attributes?
Visual attributes are the font, color, pattern proprieties that you set for form and menu objects that appear in your application interface.
60 What are three panes that appear in the run time pl/sql interpreter?
1.Source pane. 2. interpreter pane. 3. Navigator pane.

Frequently transfering databases between MS SQL and Oracle

Hello all,
I am looking for a solution to easily, efficiently and be able to migrate/transfer databases between MS SQL and Oracle frequently.
I need to be able to replicate a databases on Ms SQL and Oracle for testing purposes. I will need to do this on frequent basis - almost once a week.
Please suggest what would be the best way.
Thanks in advance.

Hi Justin,
You have guessed it right to a great extend. Yes dont actually need to develop, rather need to test an application that supports SQL and Oracle databases. Now when testing the application its obviously vital to create proper systematic test data. This usually takes a lot of time and effort from the testing team/team-member. So, yes what I need to do is create the test data on one database(may it be SQL or Oracle) and migrate/transfer the data into the database on another server( ie. SQL to Oracle or Oracle to SQL).
So,
Are you developing a product that works against both SQL Server and Oracle and trying to synchonize development efforts?Yes, thats correct to extend, I need to test an application against both the servers, as it supports both types of databases, and try to reduce the test setup efforts (literally double the amount) that go in after manual creating same data on each type of database.
Are you trying to replicate structural changes between systems?I am not 100% sure, what you mean by this. But whats important and enough for me is to replicate the data. It would not be a lot of work to run the scripts and create empty schema objects.
Are you trying to replicate data changes between systems? The fact that you're only doing this weekly suggests that you're not working in a traditional replication environment.Yes, again as I mentioned above. It would be sufficient for me to just get a copy of the initial dataset. And then replicating changes to it would not be that important. However, if I can achieve a solution to this, I can by all means create a new database on the one server (SQL or Oracle) and take the data-set of the most recent/correct changes and replicate it on the other type of server as and when needed.
No - this is not a traditional replicating environment. I say weekly, because it is usually once in a week or forthnight that someone from the team will need to spent time to manually copy the test-data onto the another type of server in order to run the same testcases on two types of servers.
How do you handle conflicts (i.e. if I modify a row in both systems, which modification wins)? This is not really a problem in my scenario, as I only need to be able to transfer the data across to the different server and forget about the two databases actually being in-sync.
I have also, looked at DTS for a possible solution on SQL, however it seems highly un-realistic, having to map somewhere like 250 tables from the a drop-down list, only because the two database servers use different cases to represent tables internals. So, table 'Table' in my application's SQL database is called 'TABLE' is my applications Oracle database. DTS is highly inefficient in dealing with this. Also, having 250 tables move makes this a bit of a pain.
Thank you Justin for your response; I highly appreciate your inputs.

Can We use FDM as ETL tool between SQL and Oracle

I want to use FDM as ETL tool between SQL and Oracle. Can it be possible. I didn,t found any target adapter for oracle database.My source system is SQL and Target system is Oracle database.
Rahul
Edited by: user12190125 on Nov 9, 2009 4:23 AM

Rahul,
I believe this is possible to do, but not an easy one and there are a few considerations:
How much data are you processing? FDM has a lot of features which support the business process. While this is great for users and audit trail etc. it slows down performance if you want to process a lot of data. It also depends on the type of mappings you use (Like mappings are slower than explicit mappings).
How familiar are you with VBScript? There is no explicit target adapter for Oracle, but there is a data mart adapter which can be used for anything. You have to implement everything yourself though, mainly the Export and Load actions. In there you will also have to handle the the connections to the MSSQL and Oracle databases.
Check the data mart adapter and see if you feel comfortable with defining the vb code in there. There are reasons for and against this approach. ODI would probably be the better choice unless you really need to have FDM's process support.
Regards,
Matt

SQL and Oracle in synchronization

I have to synchronize for about 2 months one Oracle 9.i database and one SQL server 2000, Standard edition database, both running on Win 2K Server. Every change made on either of the databases (the best is there are only 4-5 tables reflected) has to be provided on the other side almost in real time. I choused to use SQL server as a way to do it. For Oracle I have only the ODBC connectivity (supplied for free) and I did have a lot of problems in ORA 8.1.6... Needless to say, there's no money for third party products or even new ORA transfer utility, as the 2-month are not sufficient time.
I did set up linked servers between SQL server and Oracle and trying to make some triggers working for me, but is this the best way to do it? May be somebody has better experience...
Any ideas will be greatly appreciated.
Thanks,
MJ

Do you really like to implement a two way replication between M$ SQL and Oracle?
Maybe you can try this using the heterogenous gateway and Oracle Advanced replication. Don't know if this could work our test environment would be ready but actually there's no time to try.
Will keep you informed if I know more.
In this way you don't need any third party sw and I think it could work, but never have tried it out.
Could be an interesing challenge ;-)

Oracle 8i SQL and PL/SQL plus

hi everybody, i am trying from two weeks to install oracle 8i SQL and PL/SQL plus on my PC on both Windows 2000 & XP and I installed every java runtime environment I found "the old and the new" but the SETUP insists on not working though it worked on the instructor's PC smoothly without problems.

If you are getting any errors, you should tell us. Also, you should let us know what version you are trying to install.
A very common problem at the moment is with Pentium 4 processors. If you have a Pentium 4, search the forums to find the answer.

Uses for the Action Property with SQL and Oracle DB Adapters

This thread is a complement to the Wiki Article
BizTalk: Streamlining WCF SQL and Oracle Messaging-Only and Other Patterns
The question. In what circumstances is explicitly setting the Action value with the WCF SQL and Oracle DB bindings useful or beneficial.
A complimentary question. Is it even possible to set the Action value to anything other than exactly what is required by the Message.
I ask because of three very specific behaviors of the bindings themselves:
The binding enforces a match between the Action and the Message, therefore...
There is a one-to-one relationship between the Message and Action, but...
The binding is able to correctly derive and perform the requested operation with the unspecific CompositeOperation.
For clarity, I understand how to set the Action. I. understand what the Action represents in the SOAP scheme. I understand how Action can be used as an abstraction for SOAP operations.
Thoughts?

Do you have any good suggestion to learn how to use action property with SQL and Oracle DB adapters? I learn a lot from your replies for years in BizTalk forum. :)

About SQL and Oracle

Hello, I was using a MySQL database and i will soon use Oracle8. I was wandering if Oracle authorize something like mysql_result... I'm looking too for simple documentation about connecting to an Oracle database from a php file using Sql. Do u know books or sites ? Tks

user12317666 wrote:
Does Oracle support T-SQL ? Why would Oracle support a proprietary macro-based language implementation from a competitor?
If it is not supported in Oracle, what is the major grammer difference between T-SQL and Oracle supported SQL ? Oracle has two languages. SQL. PL/SQL.
PL/SQL is formal declarative procedural language with object orientation programming features. It is based on the Ada language (close relative of the Pascal language).
SQL is fully integrated with PL/SQL. Which means that you can write and mix SQL source code with PL/SQL source code and the PL/SQL compiler will figure out which is which and where to make calls to the SQL engine for executing SQL code.
Is there any efficient way for programmer to complete T-SQL transition to Oracle SQL ? Yes. Unfortunately not the answer that you are likely hoping for.
Forget EVERYTHING you did with T-SQL.
There is no real comparison between the two. And not only many differences, but some fundamental and conceptual differences too.

Need a function name for Sql and Oracle

Retrieving value of next line by doing opteration in previous row.

Can you rephrase the question? Or better yet, provide an example? I'm not sure I understand what you are asking.
My best guess is that you are looking for the analytic functions LEAD or LAG in Oracle, assuming you are on a relatively recent Oracle version. If by "SQL and Oracle" in your subject you mean "SQL Server and Oracle" (SQL is a language that all relational databases implement, SQL Server is Microsoft's relational database), I have no idea how (or if) you can do something similar with a built-in function in SQL Server. You would want to post in a SQL Server group to see how they handle that sort of thing.

Tablespace size report for SQL and oracle servers

Hi All
is it possible to get tablespace size for all sql and oracle server in the form of report in SCOM.
Regards
Madhavi

Oracle: Table size report of Oracle is depend on the MP which yu imported into SCOM
SQL :
1) Create a group which contains folowing dynamic rule
2) Reporting workspace --> Microsoft Gneric Report --> Performace Detail
3) in the parameter area, create a new series, add group which create in step 1) and select the rule: MSSQL XXX: Collect Database Allocated Size(MB)
4) Run the report
