SqlServer链接服务器连接ORACLE，安装ORACLE

1、安装ORACLE client，从官网下载；

2、tnsnamse配置：

tnsnames路径 配置tnsnames，多个节点代表多个服务器

3、odbc配置

使用搜索功能查询到对应版本的odbc数据源 输入在tnsnameszhong中配置的tns service name 点击Test Connection，输入密码点击ok，测试成功则

4、建立链接服务器

USE [master]

GO

/****** Object:  LinkedServer [ORCL]    Script Date: 2019/10/16 9:59:32 ******/

EXEC master.dbo.sp_addlinkedserver @server = N'ORCL', @srvproduct=N'ORACLE', @provider=N'MSDASQL', @datasrc=N'192.168.0.66/ORCL'

/* For security reasons the linked server remote logins password is changed with ######## */

EXEC master.dbo.sp_addlinkedsrvlogin @rmtsrvname=N'ORCL',@useself=N'False',@locallogin=NULL,@rmtuser=N'TEST20190122',@rmtpassword='TEST20190122'

建立成功

5、测试查询

大功告成
