Question

我尝试在插入触发器后创建，只要我使用ID在对面的表中插入相同的行，就从表中删除一行

但它不起作用

Create Trigger [dbo].[MeritedDeceased] On [dbo].[Deceased]
After Insert
As
Begin
Delete From dbo.Merited Where dbo.Deceased.ID = dbo.Merited.ID
End

我认为你的意思是做这样的事情（也许）......

CREATE TRIGGER [dbo].[MeritedDeceased] ON [dbo].[Deceased]
AFTER INSERT
AS
BEGIN
    DELETE M
    FROM [dbo].[MeritedDeceased] M
    INNER JOIN Inserted I
        ON I.ID = M.ID
    ;
END
;

翻译：每次在dbo.Deceased中插入一行时，请删除dbo.MeritedDeceased中具有相同（已插入）ID的所有行。

仅供参考，此TRIGGER不会删除一行，也会删除一起插入的一批行。如果这就是你想要的，那么这应该会有所帮助。
