mysql怎么连接oracle

通过配置本地数据库的tns配置文件实现：去oracle安装目录下oracle\product\10.2.0\db_2\NETWORK\ADMIN\ 找到tnsnames.ora，用记事本打开，里边有远程数据库的tns连接配置串如下ORCL23 = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.3.23)(PORT = 1521)) ) (CONNECT_DATA = (SID = ORCL) ) )添加好ip、端口和目标数据库的实例名(SID)，然后确保tns名称(ORCL23)在整个文档中唯一，保存后打开数据库连接工具，输入远程数据库上的用户名密码，选择数据库对象为你配置的连接名就可以了。还有一种方法就是配置Database Link，详情参考下帖***隐藏网址***
