如何拒绝所有用户在表上删除

Question

在SQL Server 2005中,是否有一种方法,使用单个语句,拒绝删除特定表中的行,以供数据库的所有用户使用？

Answer 1

试试这个:

CREATE TRIGGER yourTriggerName ON YourTableName
INSTEAD OF DELETE
AS

    ROLLBACK
    RAISERROR('ERROR, DELETEs not permitted in YourTableName!!!',16,1)
    RETURN

go

工作样本:

CREATE TABLE XYZ  (RowID int)
INSERT XYZ VALUES(1)
INSERT XYZ VALUES(2)
go 

CREATE TRIGGER yourTriggerName ON XYZ
INSTEAD OF DELETE
AS

    ROLLBACK
    RAISERROR('ERROR, DELETEs not permitted in XYZ!!!',16,1)
    RETURN

go

delete XYZ

OUTPUT:

Msg 50000, Level 16, State 1, Procedure yourTriggerName, Line 6
ERROR, DELETEs not permitted in XYZ!!!
Msg 3609, Level 16, State 1, Line 1
The transaction ended in the trigger. The batch has been aborted.
