Oracle如何建立DBlink

方法1：执行创建sql语句：

 

create public database link TEST_DBLINK
  connect to TEST_ISP identified by TEST_ISP
  using '(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST =192.168.1.50)(PORT = 8080))
)
(CONNECT_DATA =
(SERVICE_NAME =orcl)
)
)'
;

 

 

 

 

遇到的问题：missing IDENTIFIED keyword 原因是

identified by 密码没填写

注意：url和用户名，密码需要填写。USERNAME，PASSWORD，url，port,servicename
方法2：PL/SQL中创建

 

 

 

执行语句查询：

 

select * from tableName @TEST_DBLINK
