How to use DML Statements in a Function

You can use DML inside a PL/SQL function.However, the function can only be called from PL/SQL, not from SQL.


Generally you cannot do a dml in function and call the function in select.. The reason is "Select statement should not alter any data".. "SELECT" is not coming under DML.. but again by using Pragma Autonomous Transaction you can do.. The reason is when u use Pragma Autonomous Transaction, the DML Part will be executed in a Seperate Session (not from the Session where u issued select call).. but its never a god idea... Dont use DML in functions... Use Procedures



We can not place any DML statement inside a function simply and also a function with a DML statement cannot be used inside a SELECT query.
Here is a small example supporting the above statement:
CREATE OR REPLACE
  FUNCTION fun1(i_empno IN NUMBER)
    RETURN NUMBER
  AS
    i_count NUMBER;
  BEGIN
    --
    DELETE FROM emp WHERE empno = i_empno;
    --
    i_count:=sql%rowcount;
    --
    RETURN i_count;
  END;
  /
If we try to run the above function in a select query, the oracle engine throws the error as shown below:
SQL> SELECT fun1(1) FROM dual;
 
ORA-14551: cannot perform a DML operation inside a query 
ORA-06512: at "SYSTEM.FUN1", line 6
14551. 00000 -  "cannot perform a DML operation inside a query "
*Cause:    DML operation LIKE INSERT, UPDATE, DELETE OR select-for-UPDATE
           cannot be performed inside a query OR UNDER a PDML slave.
*Action:   Ensure that the offending DML operation IS NOT performed OR
           USE an autonomous TRANSACTION TO perform the DML operation WITHIN
           the query OR PDML slave.
But we can run the above DML statement based function in an anonymous block as shown below:
DECLARE
  a NUMBER;
BEGIN
  a:=fun1(7369);
  dbms_output.put_line(a);
END;
/
To use a DML statement inside a Function and also to use that function inside a SELECT query, we have to use PRAGMA AUTONOMOUS_TRANSACTION inside the function.
CREATE OR REPLACE
  FUNCTION fun2(
      i_empno IN NUMBER)
    RETURN NUMBER
  AS
    pragma autonomous_transaction;
    i_count NUMBER;
  BEGIN
    DELETE FROM emp WHERE empno=i_empno;
    i_count:=sql%rowcount;
    COMMIT;
    RETURN i_count;
  END;
  /
You can use the above function ‘fun2’ in a select query as shown below:


Function can use Out/Inout Parameter 

Can we use an OUT/INOUT parameter in a function?

Yes of course.

A Small example:

CREATE OR REPLACE FUNCTION TEST(A IN NUMBER, B IN OUT NUMBER,
C OUT NUMBER) RETURN NUMBER IS
D NUMBER(3);
BEGIN
B := B + A;
C := B;
D := A + B + C;
RETURN D;
END;


DECLARE
A1 NUMBER(3) := 10;
B1 NUMBER(3) := 20;
C1 NUMBER(3) := 30;
D1 NUMBER(3) := 40;
BEGIN
D1 := TEST(A1,B1,C1);
DBMS_OUTPUT.PUT_LINE(A1 || ' ' || B1 || ' ' || C1 || ' ' || D1);
END;

Description: workflow queries for debugging,oracle workflow debugging queries

As an oracle apps technical consultant, we often deal with Oracle Workflow issues.To debug these issues we found following queries to be of immense use:


SQL Query To Find Out All Workflow Items For A Given Item Type:

How to generate the XML Debug Logs

How to generate the XML Debug Logs (Output Post Processor) for 'Payment Register'.
How to generate the XML Debug Logs (Output Post Processor) for 'Payment Register'.


1. Create the temp directory in $XDO_TOP
On the applications tier move to $XDO_TOP
 - create a temp directory - mkdir temp
 - set the permissions - chmod 777 temp
 - Use pwd and copy this directory location - it will be used in step 2


[applmgr@hostname ~]$ cd $XDO_TOP
[applmgr@hostname 12.0.0]$ mkdir temp


2. Create the Debug Config file
On the Applications Tier - change to $OA_JRE_TOP/bin - cd $OA_JRE_TOP/bin
- Execute this command - ./java -verbose | grep jre | grep 'java.lang.Runtime '
   -In the results - the complete path is present showing where the rt.jar resides
   - change to this directory - this is where the xdedebug.cfg should be created
- Use vi to create a new file called xdodebug.cfg

Enter these two lines:
LogLevel=STATEMENT
LogDir=complete_path_to_$XDO_TOP/temp directory you created


[applmgr@hostname 12.0.0]$ cd $OA_JRE_TOP/bin
[applmgr@hostname bin]$ ./java -verbose | grep jre | grep 'java.lang.Runtime '
[Loaded java.lang.Runtime from /app/apps/tech_st/10.1.3/appsutil/jdk/jre/lib/rt.jar]
[applmgr@hostname bin]$ cd /app/apps/tech_st/10.1.3/appsutil/jdk/jre/lib/
[applmgr@hostname lib]$ vi xdodebug.cfg
[applmgr@hostname lib]$ vi xdodebug.cfg
[applmgr@hostname lib]$ cat xdodebug.cfg
LogLevel=STATEMENT
LogDir=/app/apps/apps_st/appl/xdo/12.0.0/temp
[applmgr@hostname lib]$




3. Restart the Middle tier
cd $INST_TOP/admin/scripts
./adstopall.sh apps/apps
./adstrtall.sh apps/apps



4. Engage PO Output for Communication - using standard style sheet

Purchasing - Reports/Run
 - Pass in the parameters to print the purchase order
 - Leave the Debug parameter as the default
 - Submit the request

5. Retrieve the logs

Move to $XDO_TOP/temp
 - Here there are files crearted, please collect these and put into a zip file.

Enabling XDO logging in EBS in 12.1.3

Introduction:
Some times ORACLE support team asks to get XDO logs to trouble sheet problems related to XML Publisher reports or where XDO processing is used. 

Follow below steps to enable XDO logging 

Steps:
a. Connect to the Apache server as applmgr
b. Create an $XDO_TOP/temp and an $XDO_TOP/resource directory
c. Create an xdodebug.cfg file in the $XDO_TOP/resource directory (do not re-create if the file already exists), containing the following 2 lines:
LogLevel=STATEMENT
LogDir=[full XDO_TOP]/temp

d. Restart the Apache server.

Note full full XDO_TOP means complete path

Note: The xdodebug.cfg file can also be created in the $OA_JRE_TOP/jre/lib directory.
