Hi,
i am trying to call in select statement it is working fine but when I try to call in >>where clause it gives me this I am suspecting the same function call is working fine in SELECT and not in WHERE clause.
Please have a look:
  1  CREATE OR REPLACE FUNCTION f1
  2     RETURN NUMBER IS
  3  BEGIN
  4     return 1;
  5  EXCEPTION
  6     WHEN OTHERS THEN
  7     return -1;
  8* END;
SQL>/
Function created.
SQL>
SQL>SELECT f1 FROM DUAL;
        F1
         1
1 row selected.
SQL>SELECT sysdate FROM dual WHERE 1=f1;
SYSDATE
15-MAY-06
1 row selected.

ORA-06512: at line 5It would be better to understand if you post your function and how you are calling.
