SQL Server 連接服務(wù)器 link server 存儲(chǔ)過(guò)程

有時(shí)候我們需要查詢遠(yuǎn)程服務(wù)器的數(shù)據(jù)庫(kù)，查詢的方式 [servername].[dbname].[owner].[object]
比如 Select * from [172.10.10.2].[test].dbo.table
但是在沒(méi)有建立link server之前是不可以查的,這里我寫了一個(gè)通用的存儲(chǔ)過(guò)程來(lái)建立link server的。

代碼如下：

Create procedure [dbo].[usp_PUB_Addlinkserver] 
(
@ServerIP varchar(30),
@UserID varchar(50),
@Password varchar(50)
)
AS
Declare @Testlinkserver varchar(500)
IF Exists(select  *  from  master.dbo.sysservers  where  srvname=@ServerIP)
BEGIN
 Select 'Failed' as iResult,'Link Server already exist!' as iDescription,@ServerIP as ServerIP
 --Exec   sp_dropserver  @ServerIP,'droplogins'
return
END
Begin Try
 Exec   sp_addlinkedserver     @ServerIP,'','SQLOLEDB',@ServerIP   
 Exec   sp_addlinkedsrvlogin   @ServerIP,'false',null,@UserID,@Password  
 set @Testlinkserver='Select top 1 *into #tmp from ['+@ServerIP+'].master.dbo.sysservers '
 Exec(@Testlinkserver)
Insert into __Temp
 Select 'Succeed' as iResult,'Operation Completed!' as iDescription,@ServerIP as ServerIP

 return
END Try
BEGIN Catch
Insert into __Temp
 Select 'Failed' as iResult,'UID password incorrect!' as iDescription,@ServerIP as ServerIP
 Exec sp_dropserver  @ServerIP,'droplogins'
END Catch
