Question about an event in a procedure

[To bi]

Hey community!

I have a little problem with my sql code...
I need to create an event dynamic ba a procedure!

So I have tested this code:

DROP PROCEDURE if exists eventProc //
CREATE PROCEDURE eventProc()
BEGIN
DECLARE dauer VARCHAR(50);

SELECT parameter.wert INTO dauer
FROM parameter
WHERE parameter.name = 'lohndauer';


DROP EVENT `newEvent`;
CREATE EVENT `newEvent` ON SCHEDULE EVERY dauer STARTS '2012-01-20 10:00:00' ON COMPLETION NOT PRESERVE ENABLE DO CALL myProc();

END;
//




I get this message but I don't know why... maybe anybody can help me!

#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'STARTS '2012-01-20 10:00:00' ON COMPLETION NOT PRESERVE ENABLE DO CALL myProc();' at line 11



Thanks a lot!
