使用 DSN 连接设置 SQL 链接服务器

Question

We have Ctree Database ODBC Drivers which is installed and configured on our local system. We have DSN Connection which is ready to use.

Using DSN Connection, i need to establish SQL Linked Server Connection. I am very new to SQL Linked Server Connection settings. I am looking for more articles and help which could help me to establish SQL Linked Server Connection settings with DSN Connection.

Answer 1

Use something like this (the name of the linked server will be CTREESRV):

USE [master]
GO
EXEC master.dbo.sp_addlinkedserver @server = N'CTREESRV', @srvproduct=N'Ctree', @provider=N'MSDASQL', @datasrc=N'DSN_NAME_HERE', @location=N'SOMETHING', @provstr=N'DNS=DSN_NAME_HERE;UID=DSN_USRNAME_HERE;PWD=DSN_PASSWD_HERE', @catalog=N'DATABASENAME_HERE'

GO
EXEC master.dbo.sp_serveroption @server=N'CTREESRV', @optname=N'collation compatible', @optvalue=N'false'
GO
EXEC master.dbo.sp_serveroption @server=N'CTREESRV', @optname=N'data access', @optvalue=N'true'
GO
EXEC master.dbo.sp_serveroption @server=N'CTREESRV', @optname=N'dist', @optvalue=N'false'
GO
EXEC master.dbo.sp_serveroption @server=N'CTREESRV', @optname=N'pub', @optvalue=N'false'
GO
EXEC master.dbo.sp_serveroption @server=N'CTREESRV', @optname=N'rpc', @optvalue=N'false'
GO
EXEC master.dbo.sp_serveroption @server=N'CTREESRV', @optname=N'rpc out', @optvalue=N'false'
GO
EXEC master.dbo.sp_serveroption @server=N'CTREESRV', @optname=N'sub', @optvalue=N'false'
GO
EXEC master.dbo.sp_serveroption @server=N'CTREESRV', @optname=N'connect timeout', @optvalue=N'0'
GO
EXEC master.dbo.sp_serveroption @server=N'CTREESRV', @optname=N'collation name', @optvalue=null
GO
EXEC master.dbo.sp_serveroption @server=N'CTREESRV', @optname=N'lazy schema validation', @optvalue=N'false'
GO
EXEC master.dbo.sp_serveroption @server=N'CTREESRV', @optname=N'query timeout', @optvalue=N'0'
GO
EXEC master.dbo.sp_serveroption @server=N'CTREESRV', @optname=N'use remote collation', @optvalue=N'true'
GO
USE [master]
GO
EXEC master.dbo.sp_addlinkedsrvlogin @rmtsrvname = N'CTREESRV', @locallogin = NULL , @useself = N'False'
GO
