sql 增加數據的例子

ALTER trigger createPerson on Person
for insert
as
begin
declare @name nchar(10)

select @name=name from inserted
INSERT INTO PersonCopy
(
?
?name
)
VALUES
(
?@name
)
print '結果為： '+@name
?--insert into storeInfo(storeID,mID) values((select mID from ))

end

sql 修改數據時的觸發器

USE [hh]
GO
/****** 對象:? Trigger [dbo].[UpdatePerson]??? 腳本日期: 05/15/2013 08:58:27 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER trigger [dbo].[UpdatePerson]
on [dbo].[Person]
??? for update
as
??? declare @oldName nchar(10), @newName nchar(10);
??? --更新前的數據
??? select @oldName = name from deleted;
??? if (exists (select name from PersonCopy where name=@oldName ))
??????? begin
??????????? --更新后的數據
??????????? select @newName = name from inserted;
??????????? update PersonCopy set name = replace(name, @oldName, @newName) where name=@oldName ;
??????? end

?sql 刪除觸發器

alter TRIGGER DeletePerson ON Person
FOR delete
AS
BEGIN
?DECLARE @name? nchar(10);
?SELECT @name=name FROM deleted
?DELETE FROM PersonCopy WHERE name=@name
end

?sql判斷觸發器是否存在

if (object_id('createPerson', 'TR') is not null)
??? drop trigger createPerson
