CREATE PROCEDURE test_proc_ins1(
         IN i_id INT,
         IN i_name VARCHAR(100),
         OUT o_ret INT)
BEGIN
         DECLARE EXIT HANDLER FOR SQLSTATE '23000' set o_ret = -1;
-- 也可以这样使用：
-- DECLARE EXIT HANDLER FOR SQLWARNING,NOT FOUND,SQLEXCEPTION set o_ret=-1;
         INSERT INTO testproc VALUES (i_id,i_name);
         INSERT INTO testproc VALUES (i_id,i_name);
