On ORACLE a FUNCTION MUST return a value. If the FUNCTION doesn't
return a value Oracle give a 'hint' on FUNCTION compilation and error
on SELECT function invocation: ORA-06503.
When we don't want to return any result on ORACLE we must use
PROCEDURE statement instead of FUNCTION.
Example:
========
SQL> CREATE OR REPLACE FUNCTION F_test RETURN NUMBER IS 2 BEGIN 3 NULL; 4 END F_TEST; 5 /
Function created.
SQL> SELECT F_TEST FROM DUAL;
SELECT TUZSA.F_TEST FROM DUAL *
ERROR at line 1:
ORA-06503: PL/SQL: Function returned without value
ORA-06512: at "F_TEST", line 3
SQL>
========
