触发器问题,这已经是第三次问了,高手拜托看看啊
我写了个这样的触发器.顺便说下,表ntt里有no,no_no,ct这3个字段,no字段是个auto_increment列
CREATE TRIGGER ntt_ct BEFORE INSERT
ON ntt FOR EACH ROW BEGIN
UPDATE ntt SET ct=1 WHERE no=NEW.no_no;
END
那个替换;用的DELIMITER |我当然也加了
但现在我如果执行INSERT语句,就会出如下错误
Can ‘t update table ‘ntt ‘ in stored function/trigger because it is already used by statement which invoked this stored function/trigger
这是怎么回事
CREATE OR REPLACE TRIGGER “ntt_ct ” AFTER
UPDATE ON ntt FOR EACH ROW
declare
stmt varchar2(500);
begin
stmt := ‘ UPDATE ntt SET ct=1 WHERE no=NEW.no_no; ‘
/
