plsqldev鏈接sql
1.鏈接不一樣服務器,要修改tnsnames.ora文件,具體以下修改以下位置服務器
# tnsnames.ora Network Configuration File: \app\usr\admin\orcl\tnsnames.ora # Generated by Oracle configuration tools.app
ORCL = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521)) ) (CONNECT_DATA = (SERVICE_NAME = orcl) ) )spa
2.鏈接同一服務器,不一樣庫時,在登陸時,輸入不一樣的庫名和密碼blog
sqldeveloper鏈接時:簡單,只需按下面配置上便可io
plsqldev與sqldeveloper:sqldeveloper比plsqldev簡單的多,可是還有不少人及客戶要用plsqldev,不得已選擇plsqldev登錄
