MySQL Stored Procedure Calling MySQL Stored Procedure
I have two MySQL Stored Procedure,
CREATE Procedure proc1(
IN alpha VARCHAR(10)
, OUT Beta VARCHAR(55)
) --blah blah blah code for proc
CREATE Procedure proc2()
BEGIN
DECLARE l_alpha VARCHAR(10);
DECLARE l_beta VARCHAR(55);
CALL proc1(l_alpha, l_beta);
END
Why am I getting
ERROR 1414 (42000): OUT or INOUT argument 2 for routine schema.proc1 is not a variable or NEW pseudo-variable in BEFORE trigger
??
Is there any other method around this? best practice?

No triggers what so ever...
What i was trying at the time when I got that message was to have one stored Proc call another stored Proc.
so, proc 2 calls proc 1. proc 1 does it thing, then return the result using INOUT variables of MySQL and return that to proc 2.
I was trying to get proc 2 to read this returned variable and use it. Then this problem showed up when I tried to create th proc.
