在图1中选中“链接服务器”，右键选择“新建链接服务器”，如图2，配置相关参数。

在“常规”选项中，填写“链接服务器名称”，访问接口选中

“ Microsoft OLE DB Provider for Oracle”项。其中产品名称、数据源、访问接口字符串请填写配置的Oracle客户端在本地配置的net服务名。如图3所示。

在“安全性”项中，选中使用此安全上下文建立连接，填写远程登录用户和密码，即登录远程Oracle服务器的用户和密码。如图4所示。

比如我们建立了链接服务器ORADBCONN，而Oracle中在HRSOFT用户下面建立了表WEBUSER，那么我们的SQL语句就是：

--清空Oracle表中的数据

DELETE  FROM  ORADBCONN..HRSOFT.WEBUSER

--将SQLServer中的数据写到Oracle中

INSERT  into  ORADBCONN.. HRSOFT. WEBUSER

SELECT * FROM WEBUSER

如果报告成功，那么我们的数据就已经写入到Oracle中了。

用SELECT * 　FROM  ORADBCONN..HRSOFT.WEBUSER

查看Oracle数据库中是否已经有数据了。

A、查询Oracle数据表方式一(这种方式，当Oracle与SQLServer的数据类型不一致时经常报错,且速度稍慢)：

select * from [LINK2ORACLE]..[ORACLE_USER_NAME].TABLE_NAME;

　　我在执行该语句经常报类似错误信息：链接服务器 "LINK2ORACLE" 的 OLE DB 访问接口 "MSDAORA" 为列提供的元数据不一致。对象 ""CMCC"."OS2_GIS_CELL"" 的列 "ISOPENED" (编译时序号为 20)在编译时有 130 的 "DBTYPE"，但在运行时有 5。

　　B、查询Oracle数据表方式二(经试验，这种方式使用起来很顺畅，不报错，且速度几乎和在Oralce中一样快)：

　　select * from openquery(LINK2ORACLE,'select * from OracleUserName.TableName')

　　您可以把openquery()当成表来使用。

　　C、举个例子（将Oralce用户HRSOFT下的用户表WEBUSER导入到SQLServer2005数据库中）：

　　select * into OS_GIS_WEBUSER from openquery(LINK2ORACLE,'select * from HRSOFT. WEBUSER)

　　D、更便捷的方式：通过创建同义词进行便捷查询:

　　CREATE SYNONYM OS_GIS_CELL FOR [ORACLELK]..[CMCC].OS_GIS_CELL;

　　select * from os_gis_cell;

　　select * from os_gis_cell a where a.CellName is null;

注意：涉及 Oracle 部分的 SQL 语句，尤其是 [ORACLELINK]..[ORACLE_USER_NAME].TABLE_NAME 一定要大写，否则会报类似错误：

消息 7314，级别 16，状态 1，第 1 行

链接服务器 "ORACLELK" 的 OLE DB 访问接口 "MSDAORA" 不包含表 ""CMCC"."OS2_gis_CELL""。该表不存在，或者当前用户没有访问该表的权限。
