Mysql触发器错误r\u CANT\u UPDATE\u USED\u TABLE\u IN\u SF\u或\u TRG:Can&\x27；t更新表

当数据插入到同一个表中时，我使用了一个触发器来更新表！但当我在那个表中插入数据时，我得到了一个错误

ER_CANT_UPDATE_USED_TABLE_IN_SF_OR_TRG: Can't update table

这是什么意思

触发代码：

create trigger update_owners_leaving_time 
AFTER INSERT ON cc_owners_queries 
FOR EACH ROW BEGIN
update cc_owners_queries set leaving_time = query_time + INTERVAL leaving_in MINUTE , trigger_updated = 1 where trigger_updated !=1;
    END

错误：

 Error: ER_CANT_UPDATE_USED_TABLE_IN_SF_OR_TRG: Can't update table 'cc_owners_queries' in stored function/trigger because it is already used by statement which invoked this stored function/trigger.

你必须这样做：

create trigger update_owners_leaving_time 
AFTER INSERT ON cc_owners_queries 
FOR EACH ROW BEGIN
    IF NEW.trigger_updated != 1 THEN
        set NEW.leaving_time = NEW.query_time + INTERVAL NEW.leaving_in MINUTE;
        SET NEW.trigger_updated = 1;
    END IF;
END

您不必说需要更新当前表。你绕着行走。。这一行将成为目标

更多信息：

可能是因为更新触发了该触发器，这将导致无限循环？@Niels我没听明白！触发器将导致更新。哪个会触发，哪个会更新，哪个会触发，，等等。@vipulsodha你能分享一下你的触发器代码吗？@Mureinik是的，我做到了！
