oracle server sql by server illustrate connect

本文以SQL Server 2k为例说明SQL Server到Oracle连接服务器的具体实现过程。
 
1.要求pc机上安装oralce客户端软件和sqlserver2000软件。
 
2.客户端的配置tnsnames.ora文件,配置所要连接的数据库服务器(windows,unix等平台均可以)
eg:tnsnames.ora
......
TEST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.1.11.90)(PORT = 1521))
)
(CONNECT_DATA =
(sid = blue)
(SERVER = DEDICATED)
)
)
......
3.配置windows的ODBC数据源:
开始菜单—》设置—》管理工具—》数据源(ODBC)—》进入配置用户DSN或者系统DSN均可以:添加—》选择Microsoft ODBC for oracle—》自定义数据源名称(最好跟tns中连接串同名!)—》服务器名称(必填!填写tns文件中的连接串名称)—》完成。
 
4.配置sqlserver2000中的连接服务器:
企业管理器—》安全性—》连接服务器—》右键新建连接服务器—》定义连接名称; 选其他数据源; 指定程序名称为:Microsoft OLE DB Provider for Oracle; 产品名称可不填; 数据源指定刚才ODBC中定义好的数据源名称; 提供程序字符串按以下格式填写:User ID=username;Password=userpasswd(或者按如下格式:UID=username;PWD=userpasswd),这里的用户名和密码对应所要连接的oracle数据库中的用户名和密码 —》 安全性标签页里:设置用此安全上下文进行,并录入oracle的数据库用户名和密码—》服务器选项标签页可默认—》确定。
 
5.准备工作全部完成啦!在sqlserver企业管理器—》安全性—》连接服务器打开刚建好的连接服务器—》点击表,即可在右边窗口看到该oracle数据库用户拥有的的所有表名,但在这里还并不能查看表的记录,这个需要在sqserver的查询分析器中用具体sql实现!访问表时,使用格式为: [连接服务器名]..[ORACLE用户].[表名]。更详细具体的使用这里不再赘述。
