MySQL触发器删除相同的ID

Question

使用TRIGGER，我想删除table2中具有与id在table1中删除的行相同的ID的行

CREATE TRIGGER trgDeleteInTable2 AFTER DELETE ON table1
FOR EACH ROW
BEGIN
DELETE  FROM table2 a  WHERE a.id =  the same id than the one deleted in table1 
END;

我该怎么办？如何获取表1中删除的当前ID？

感谢您的帮助

尝试一下：

CREATE TRIGGER trgDeleteInTable2 AFTER DELETE ON table1
FOR EACH ROW
BEGIN
DELETE * FROM table2 a  WHERE a.id =  OLD.id 
END;

OLD.id是已被删除的id中的table1。
