I wrote this procedure

PROCEDURE "Probe1" (IN "ID" INTEGER)
BEGIN
DECLARE Result CURSOR WITH RETURN FOR Stmt;
 BEGIN
 PREPARE Stmt FROM 'SELECT * from probe where z1 = ?';
 Open result using ID;
 END;
END

In ElevateDBManager I got 0 records.
When I replace the "?" with a real number then the proc works fine.

What do I wrong?
TIA

Sorry for this post, I found the error.
