Oracle DB Link 记要
Oracle DB Link 记录
方法一：通过代码书写oracle db link;
create public database link test_link2
connect to twc identified by twc using
'(description =
(address_list=
(address = (protocol = TCP)(HOST=192.168.0.129)(PORT = 1521))
)(connect_data =
(service_name = LHW)
))';
select * from twc.sfzinfo@test_link2;
备注:其中test_link2为dblink名称,twc /twc 为oracle数据库用户名和密码,HOST为远程数据库的IP地址，PORT为数据库的端口号,service_name 为Datebase服务器名称;
方法二：通过PL/SQL写，之前已写过，就不再描述；
