Problem with DECODE statement while migrating forms to 6i

Question

Hi,
I'm migrating a form from 5 to 6i. When I compiled the form, I got this error witha decode statement.
The error is
Error 307 at line 15 column 7
too many declarations of "DECODE" match this call
The trigger has this code:
IF :PRUN_RECS_INSERTED = 'Y' THEN
      RETURN ;
   END IF ;
   INSERT INTO GJBPRUN
    ( GJBPRUN_JOB,
      GJBPRUN_ONE_UP_NO,
      GJBPRUN_NUMBER,
      GJBPRUN_ACTIVITY_DATE,
      GJBPRUN_VALUE )
   SELECT :KEYBLCK_JOB,
          :ONE_UP_NO,
           GJBPDFT_NUMBER,
           SYSDATE,
      DECODE(GJBPDFT_VALUE, 'SYSDATE',
                      DECODE(GJBPDEF_LENGTH,'11',TO_CHAR(SYSDATE,'DD-MON-YYYY'), SYSDATE),
                      GJBPDFT_VALUE)
   FROM   GJBPDFT G, GJBPDEFEdited by: Charan on Mar 16, 2011 9:15 AM

Hi Charan
i think it's all about using both CHARACTER and DATE values at the same time in a DECODE statment u should either use char or date datatype.
DECODE compares expr to each search value one by one. If expr is equal to a search, then Oracle Database returns the corresponding result. If no match is found, then Oracle returns default. If default is omitted, then Oracle returns null.
e.g.
If expr and search are character data, then Oracle compares them using nonpadded comparison semantics.
expr, search, and result can be any of the datatypes CHAR, VARCHAR2, NCHAR, or NVARCHAR2.
The string returned is of VARCHAR2 datatype and is in the same character set as the first result parameter.

Hope this helps,
