Oracle Interview Qs

1. What is dynamic sql?

Ans:- pl/sql uses early binding , so we cant execute DDL statements in pl/sql.
To over come this situation we have two options

   1> we can use EXECUTE IMMIDIATE statement
   2> we can use DBMS_SQL package

2. Tell me 5 important tables in GL (GENERAL LEDGER)


3. What are User Exits
    A user exit is a 3rd Genaration Language  program where it can be linked to the report builder executable
   There are 3 types of user interfaces

    a>  ORACLE user interfaces
    b>  OCI (Oracle Caller Interface)
    c>  None-Oracle user exit

4. What are the User Parameters in User Exits?

          srw.user_exit ('FND SRWINIT');
              user exit is the mandatory parameter in srw.user_exit

5. How many interfaces in GL, AP what are they?

    3 interfaces in GL.

6. Is it possible to use User Exits in Report builder? How.

   In BEFORE REPORT we call srw.user_exit ('FND SRWINIT')
   In AFTER REPORT we call srw.user_exit ('FND SRWEXIT')

7. Diff between functions and procedures

   Procedure is called as pl/sql statement
   Function is called as an expression and it can called from SELECT statement.

8. Diff between ap_invoice_all and ap_invoice

     The _all tables are sharable in multi oraganization environment and it contains ORG_ID field.
Ex: fnd_client_info.set_org_context(‘204’) ;

10. Place holder, summary columns, formulae columns?

   Place holder is a column for which you set the data type and value in PL/SQL that u define.
 This can be used in BEFORE REPORT Trigger, if the placeholder is a report level trigger.
 A report level formula column, if the place holder is a report_level column
 A formula in the placeholder's group or a group below it (The value is set only once for each record
of the group).

   A summary column can be either report level or group level is used to get the    value of built in function on a single column.

   A formula column can be either report level or group level is used to get the     values from one or more columns.

11. Multi org concepts?

        It is a server side enhancement where multiple business units can use a single Installation of oracle product.

     The architecture of multi org is, Business group, set of books, operating units,      Inventories.

  ORG_ID is stored in operation units and ORGANIZATION_ID is stored in inventories. There is one-to-many relationship between them.

12. Lexical parameters and bind parameters?
Lexical parameter is a replacement of text string in select statement, it is preceded by & (ampersand).
For this we need to create user parameter, It should be character and initialized. We need to pass the values at runtime for this lexical parameter.

 Bind parameter is a replacement of  single value or expression in select statement.         It is preceded by colon(:). It can be number, date, or character data type .It cannot be used in FROM clause.

13. How can we execute the query in the report trigger?

  Using SRW.DO_SQL we can execute the DDL and DML queries.
This procedure executes the specified SQL statement from within Report Builder.
The SQL statement can be DDL, or DML (statements that manipulate data). 

14. Firing sequence of report triggers?

15.key flexfield, and descriptive flexfield.

 Key flex fields captures the unique information, and descriptive flexfields captures the more information.
 The key flex field in GL is Accounting Flex Field.
 The KFF in AR are Territory and Sales tax.

16. where will you write user exits 

   The FND SRWINIT in BEFORE REPORT trigger and
   the FND SRWEXIT in AFTER REPORT trigger.

17. What is mutating table.
  A trigger is trying to modify the triggering table. To overcome this we need to use temporary table and views.

  A table in transition then we called that table is mutating.
18. What is Retcode, and Errbuff?                                                   
    These are mandatory parameters when we write concurrent program using stored procedures.

RETCODE contains 3 values 0-for sucess,1-sucess with warnings, 2-errors.
ERRBUFF contains error message.
  Concurrent manager will fill the values for these parameters.

19. Request group?

  Collection of requests, request sets and concurrent programs that a user can operate under a given responsibility.

20. What are the mandatory paramenters we have to pass in report?


21. What is a data group?

    A data group is a collection of Oracle Applications and the user names assigned   to  Each application. Generally the user name is apps schema.

22. What is short name, and base path?

    A short name is used to identify menus, forms, concurrent programs, and other application components.
        A base path is top directory in applications directory tree.

23.Is table registration is mandatory in apps?
    No, but when ever we use flex fields and alerts then it is mandatory.

24. What are the procedures used for registration and deletion of tables in apps?

    AD_DD.REGISTER_TABLES(appl short name,
                        table name,
                        table type,
                        pct. Next extent,
                        pct. free,

                        table name,
                        column name,
                        column seq,
                        data type,
                        transferable); and optional precission.
    AD_DD.DELETE_COLUMN(appl short name,
                        table name,
                        column name)
    AD_DD.DELETE_TABLE(appl short name,
                        table name)

75. How can you know that whether multi_org enabled or not?

        SELECT multi_org_flag

76. Where are triggers stored ?


77. What is mutating table error ?

        A trigger is trying to access the triggering table is called mutating table error.
This situation can be over come using Temporary tables and views.

78. what happens when we use RAISE?

        It reraise the same exception, but the control goes to the immediate outer block.

79. Which implementation methodology you are using?

        AIM (Application Implementation Method).
80. What are pragmas in PL/SQL?

        Pragma is a precompiler directive. These are processed at compile time.


81. How do you set the character report in D2K?

        Set 'yes' to the 'Design in character units' of the report property, and
'character' to the 'Intial Value' of the MODE system parameter.

82. what are the attributes of the cursors ?

85. What are the types of joins?

         1> Inner Join
         2> Outer Join
         3> Self Join


        It tells the compiler to associate an exception name with oracle error number.


        It is a fully independent transaction started by the parent transaction. It doesn't share any resources with the parent transaction. The autonomous transaction should end with either ROLLBACK or commit.
        Generally in triggers we should not use transaction control statements, but, with autonomous trigger we should use transaction control statements.


        Is used to issue user defined error message from the stored procedure.

      syntax :
         RAISE_APPLICATON_ERROR (error_number,message,[,{true/false}]);

       error_number : -20000 to -20999     

   This can be used in both executable  and exception section.

                3> System Triggers
        12 Types of DML triggers. 3 statements X 2 level X 2 timing

91. What are SQLCODE and SQLERRM in PL/SQL ?

        SQLCODE returns the error number.

        These are especially used in WHEN OTHERS exception handler.

92. What is a database link?
        A data base link is a reference to the remote database.

93. What are PL/SQL variables?

        %TYPE and %ROWTYPE are the pl/sql variables.
        %TYPE associates a variable with the table's field datatype.
        %ROWTYPE associates a variable with the table's row datatype. 

94. Where are the procedures, functions, and packages are stored?

        1> USER_OBJECTS (Procedures,functions and package body)
        2> USER_SOURCE
        3> USER_ERRORS

95. What are Materialized views?

        Materialized views are reduced sets of information used to precompute, replicate, and distribute data. These are used in distribute environment, data warehousing and DSS.

        It uses Oracle 8i features, CBO, Temporary Tables, Partitioned Tables, and Materialized views.

97. What are the parameters of the FND_REQUEST.SUBMIT_REQUEST ?

    Application short name, program name, description, start time, sub request, argument1 to argument100.

98. What is the Application Name in CP Executable and CP windows ?

   In CP Executable, Application Name determines in which directory your report executable is stored.
      In CP window, it is the name of the ORACLE user names your program runs and where to place the log and output files.

99. How do you get the ORG_ID?

100. Can we use transaction control statements in Triggers?

    Yes, we can use them only in autonomous triggers.
