HI

How can i call from function to function in Oracle pl\sql?

I need a sample program .Please clarify my doubt.Pls.


Arun..

Here's the first function declaration:

----------------------------------------------------------------------------------------------------
CREATE OR REPLACE FUNCTION firstFunc(pParm1 IN Varchar2)
RETURN BOOLEAN AS
vDate DATE;
BEGIN

SELECT sysdate INTO vDate FROM dual;

--call function two
if secondFunc(vdate) = 'WEDNESDAY' then
dbms_output.put_line("It's wednesday");
else
dbms_output.put_line("It's not wednesday");
end if;

END firstFunc;

----------------------------------------------------------------------------------------------------

Here's the second function declaration, that is called by the first:

----------------------------------------------------------------------------------------------------
CREATE OR REPLACE FUNCTION secondFunc(pParm1 IN DATE)
RETURN VARCHAR2 AS
vDay varchar2(20);
BEGIN

RETURN to_char(pParm1, 'DAY');

END secondFunc;

Thanku very much my dear friend.
