Problem with call procedure

Hello! My HeidiSQL can't run stored procedure. It has one input and one output param, but Heidi asks for both and finally reports error. Thank you Piotr

INOUT & OUT params should be variable or SQL will not be able to write in it. So you have to do something like this:

SET @a = 2; -- for INOUT
CALL myproc(1, @a);
SELECT @;

Please tell why HeidiSQL asked me for parameters which is only OUT?

Oh I guess you found a bug :)

Please report that in the issue tracker.
