mysql触发器删除相同的id

Question

我想用 TRIGGER 删除表 2 中与表 1 中删除的行具有相同 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;

我该怎么做？如何删除 table1 中的当前 ID？

感谢帮助

试试这个:

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

OLD.id 是 table1 中被删除的 id。
