使用的存储过程简介
1、sp_addlinkedserver --- 为SQL SERVER 添加一个Link Server
2、sp_addlinkedsrvlogin --- 为Link Server 添加一个 Login
3、sp_droplinkedsrvlogin --- 删除Link Server的Login
4、sp_dropserver --- 删除Link Server
详细请参考 SQL SERVER Book Online
使用的命令
1、use 切换到一个指定的数据库
2、OPENQUERY 从一个现有的Link Server 执行一个查询
Dim cn As ADODB.Connection
Dim strsql As String
Dim rs As ADODB.Recordset
'打开连接
Set cn = New ADODB.Connection
cn.Open "连接"
strsql = "use master"
cn.Execute strsql
'添加一个LinkServer
strsql = "exec sp_addlinkedserver"
strsql = strsql & " @server = 'AccessDataSrv',"
strsql = strsql & " @provider = 'Microsoft.Jet.OLEDB.4.0',"
strsql = strsql & " @srvproduct = 'OLE DB Provider for Jet',"
strsql = strsql & " @datasrc = 'C:\Test.mdb'"
cn.Execute strsql
'添加一个LinkServer Login 如果你的数据库有密码和用户认证的话
'strsql = "EXEC sp_addlinkedsrvlogin 'AccessDataSrv', 'false', '当前用户', '用户', '密码'"
strsql = "exec sp_addlinkedsrvlogin 'AccessDataSrv', 'false'"
cn.Execute strsql
strsql = "use tt"
strsql = "insert into testlinsrv(id,field2)"
strsql = strsql & " select * from OPENQUERY(AccessDataSrv,'select a1,a2 from testlinksrv')"
cn.Execute strsql
strsql = "use master"
cn.Execute strsql
'删除linksrv的login
strsql = "exec sp_droplinkedsrvlogin 'AccessDataSrv', null"
cn.Execute strsql
'删除linksrv
strsql = "exec sp_dropserver 'AccessDataSrv'"
cn.Execute strsql
'返回数据
strsql = "select * from testlinsrv"
