CREATE PROCEDURE innerproc(OUT param1 INT)
BEGIN
 insert into sometable;
 SELECT LAST_INSERT_ID() into param1 ;
END
-----------------------------------
CREATE PROCEDURE outerproc()
BEGIN
CALL innerproc(@a);
// @a gives you the result of innerproc
SELECT @a INTO variableinouterproc FROM dual;
END

OUT 参数应该可以帮助您将值返回给调用过程。基于此，解决方案必须是这样的。
