服务器之间建立oracle之间的关联语句

create public database link DBLINK_WZGTAMS CONNECT TO  WZGTAMS identified by WZGTAMS

using '
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.11.112)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SID = orcl11g)
      (SERVER = DEDICATED)
    )
  )';

接下来建立一个简单的查询验证效果

select * from 用户名下的.表@建立的远程连接名字

连接成功，

其中using里面的内容是ora文件的内容但是要去掉开始的实例名

 CONNECT TO 远程用户名identified by 远程用户密码
