SQLEXEC(conH,"SELECT * FROM {stored_proc}(parameters)")but only if the stored procedure return something back (records or values). For example, if one has a stored procedure that add a new record, this can returns 0 (successful) and the new PK or the error code and null.
SQLEXEC(conH,"EXECUTE PROCEDURE {stored_proc}(parameters)")works, but only if doesn't return something.
