在阿里云SQL窗口执行如下触发器不能正常执行

这个触发器在navicat是可以正常执行的，但是阿里云SQL窗口怎么都不行，请问下是什么问题呢？

DROP TRIGGER IF EXISTS trigger_update_mobile_apply; CREATE TRIGGER trigger_update_mobile_apply AFTER UPDATE ON employees FOR EACH ROW
BEGIN IF OLD.mobile <> NEW.mobile THEN update approval_flows set mobile = NEW.mobile where mobile = OLD.mobile; update approval_flows set approver_1 = NEW.mobile where approver_1 = OLD.mobile; update approval_flows set approver_2 = NEW.mobile where approver_2 = OLD.mobile; update approval_flows set approver_3 = NEW.mobile where approver_3 = OLD.mobile;

   update approval_flows set approver_4 = NEW.mobile where approver_4 = OLD.mobile;
   update approval_flows set approver_5 = NEW.mobile where approver_5 = OLD.mobile;
   update approval_flows set approver_6 = NEW.mobile where approver_6 = OLD.mobile;

   update approval_flows set approver_7 = NEW.mobile where approver_7 = OLD.mobile;
   update approval_flows set approver_8 = NEW.mobile where approver_8 = OLD.mobile;
   update approval_flows set approver_9 = NEW.mobile where approver_9 = OLD.mobile;

   update approval_flows set approver_10 = NEW.mobile where approver_10 = OLD.mobile;

END IF; END;
