Yes it was part of a trigger, what i am trying to do is to insert data of an old tabl into new one, the new one contains all the old colomns plus one, the code_usager_ctrl which is given by the procedure. But i don't want to use the trigger. Is that possible ? Or do i need to convert the procedure into a function.There is no way to call a procedure from a SQL statement.
You can call a function from a SQL statement, such as a query. There are some restrictions on the function. In particular, it can't have IN OUT or OUT arguments, only IN arguments. It looks like you could convert your procedure into a fucntion. The return value of the function would be what the IN OUT argument p_code_usager_ctrl is in the procedure. It looks like p_date_ctrl is always SYSDATE, so you might as well just use SYSDATE.
Here's the procedure
CREATE OR REPLACE PROCEDURE SP_INFO_ELEMENT_CTRL
( P_DATE_CTRL IN OUT DATE -- TIMESTAMP DE LA TRX
,P_CODE_USAGER_CTRL IN OUT CHAR -- CODE D'usager utilise
) AS
BEGIN
-- RECHERCHE DE LA DATE
P_DATE_CTRL := SYSDATE;
-- Si l'usager est IGD, c'est le package qui fourni le nom d'utilisateur
IF (USER = 'IGD' OR USER = 'GDI' OR USER='IGDD') AND P_CODE_USAGER_CTRL IS NOT NULL THEN
P_CODE_USAGER_CTRL := 'IGDD\'||TRIM(P_CODE_USAGER_CTRL);
ELSE
-- RECHERCHE DE L'usager
P_CODE_USAGER_CTRL := USER;
END IF;
END;
