Question

我有一个包含一些表的数据库。我想创建一个触发器'删除tblplayersfield中的记录，并在tblplayers'中删除记录的“pID”

CREATE TRIGGER delete_from AFTER DELETE on tblplayers
FOR EACH ROW
BEGIN
DELETE FROM tblplayerfields
    WHERE 'tblplayerfields'.'pID' = OLD.'pID';
END

Answer 1

您需要先添加分隔符更改

delimiter |

CREATE TRIGGER delete_from AFTER DELETE on tblplayers
FOR EACH ROW
BEGIN
DELETE FROM tblplayerfields
    WHERE 'tblplayerfields'.'pID' = OLD.'pID';
END
|
delimiter ;

分隔符表示数据库引擎结束语句。通常是;。但这会在第一个;结束存储过程。它的定义是不完整的。

您可以更改分隔符并将其添加到过程的末尾。之后，将分隔符更改回;

在MySQL中创建触发器的麻烦
