1.先創建一個test 和一個test2 兩個表
USE [WZDb]
GO
/****** Object: Table [dbo].[test] Script Date: 05/13/2013 14:21:21 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
SET ANSI_PADDING ON
GO
CREATE TABLE [dbo].[test](
[id] [int] IDENTITY(1,1) NOT NULL,
[content] [varchar](500) NOT NULL,
CONSTRAINT [PK_test] PRIMARY KEY CLUSTERED
(
[id] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
GO
SET ANSI_PADDING OFF
GO
USE [WZDb]
GO
/****** Object: Table [dbo].[test2] Script Date: 05/13/2013 14:21:45 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
SET ANSI_PADDING ON
GO
CREATE TABLE [dbo].[test2](
[id] [uniqueidentifier] NOT NULL,
[name] [varchar](50) NOT NULL,
CONSTRAINT [PK_test2] PRIMARY KEY CLUSTERED
(
[id] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
GO
SET ANSI_PADDING OFF
GO
ALTER TABLE [dbo].[test2] ADD CONSTRAINT [DF_test2_id] DEFAULT (newid()) FOR [id]
GO
2.先看一下添加的觸發器。當給test2 添加一條數據 相對應的給test1 也添加一條
USE [WZDb]
GO
/****** Object: Trigger [dbo].[trig_test2] Script Date: 05/13/2013 14:22:38 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
--=====給Test2添加數據的時候也改test1添加====
ALTER trigger [dbo].[trig_test2]
on [dbo].[test2] for insert
as
declare @name varchar(50)
-- declare @name2 varchar(50)
select @name=name from inserted
INSERT INTO [WZDb].[dbo].[test]
([content])
VALUES
(@name)
print '開始輸出'
print @name
print '輸出完畢'
2.刪除數據的觸發器
USE [WZDb]
GO
/****** Object: Trigger [dbo].[trrig_del] Script Date: 05/13/2013 14:23:08 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER TRIGGER [dbo].[trrig_del]
on [dbo].[test] for delete
AS
declare @name varchar(50)
select @name=content from deleted
if exists(select * from test2 where name=@name)
begin
delete from test2 where name=@name
print 'ddd'
end
3.更新觸發器
還沒有完全理解，后續更新
