·只有inserted表有数据时,当前操作为insert:·inserted和deleted两张表都有数据时,当前操作为update:·只有deleted表有数据时,当前操作为delete. 1. CREATE TRIGGER trTask_Update ON dbo.Task FOR UPDATE AS BEGIN DECLARE @TaskId INT DECLARE @NewTaskOrder INT DECLARE @WorkstreamId INT DECLARE @OldTaskOr
原贴地址: https://blog.csdn.net/reblue520/article/details/51580102 具体的方法为: 创建一个触发器 CREATE TRIGGER forbiddensa ON ALL SERVER WITH EXECUTE AS 'sa' FOR LOGON AS BEGIN --选择sa用户进行限制: IF ORIGINAL_LOGIN()= 'sa' --允许sa在本机登录“” AND (SELECT EVENTDATA().value('(/EVE
--创建表 create table zhuangzhan ( name ), code ) ); --往表添加一列 alter table zhuangzhan add descition int; --添加数据 select * from zhuangzhan ); ); --给表创建触发器用于添加数据出发,不允许添加code相同的数据 alter trigger mytrigger on zhuangzhan for insert as begin tran ) begin rollb
1.普通调试 直接点击SSMS客户端上的调试按钮即可 2.存储过程调试 2.1 定义存储过程(以Northwind数据库为例) USE [Northwind] GO /****** Object: StoredProcedure [dbo].[sp_getOrders] Script Date: 2014/7/7 17:32:09 ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO ALTER procedure [dbo].[sp_
1,触发器有两种 (1)After触发器(之后触发) 触发器有个好处:就是你之前有过什么操作他会将你的操作的数据信息完整的保存下来,比如你删过什么信息,如果用触发器,那么删除后就会显示两行受影响,那么我们要做的思路就是将删除后的信息保存到一个新表中,就得克隆一张操作数据的表.比如 操作表:Tb_Student select top 0* into Tb_tgStudent from Tb_Student 建完新表接着创建一个触发器 create trigger tg_triggers on
触发器是:instead of delete 类型,注意了:instead类型的触发器相当于: DELETE命令过来后,直接走触发器中的代码,再往下,没有了…… 就是说,这个触发器会屏蔽掉你所有的DELETED命令.而只会执行一下触发器中的代码. 如果你把这个触发器中的代码都注释掉,就相当于:屏蔽所有的DELETE命令. Create trigger [dbo].[trg_del] on [dbo].[drv_user] instead of delete AS BEGIN declare @c
Create TRIGGER [dbo].[tr_Delete_AllocationedDN] --删除指定账户已分配未拣货的任务 ON [dbo].[FRU_PickLocationNew] --触发的表名 AFTER UPDATE --为什么触发 AS IF UPDATE(IsUse) --哪个字段变更引发的触发? BEGIN IF ( ( SELECT IsUse FROM inserted ) ) BEGIN DELETE FROM WMS_FRU_DNAllocationToAccou
