oracle 在本地查询远程数据库的方法，如何组合远程链接字符串

方法如下： 第一、创建远程链接的link： create public database like linkorcl（创建的link名称） connect to zhang（用户名） identified by xxxx（密码） using '111.111.1.1:1521/orcl'（远程数据库ip和数据库名称）; 其他均为关键字 第二、使用创建的li

方法如下：

第一、创建远程链接的link：

create public database like linkorcl（创建的link名称） connect to zhang（用户名） identified by
xxxx（密码） using  '111.111.1.1:1521/orcl'（远程数据库ip和数据库名称）;

其他均为关键字

 

第二、使用创建的link名称进行查询即可：

select * from student@linkorcl;

 

实例如下：

SQL>
SQL> CREATE   PUBLIC   DATABASE   LINK   linkorcl CONNECT   TO   zhang IDENTIFIED   BY
  2  XXXX USING   '111.111.1.1:1521/orcl';
 
Database link created
 
SQL> select * from student@linkorcl;
