plsql首次登錄數(shù)據(jù)庫選什么?
首先你的機器要裝一個客戶端(服務(wù)器版也行) 然后在D:\Oracle9\network\admin\tnsnames.ora文件加入你要訪問的數(shù)據(jù)庫的連接串,一般形式為 my_test = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.2)(PORT = 1521)) ) (CONNECT_DATA = (SERVICE_NAME = test) ) ) 然后登錄的時候DataBase選擇my_test,用戶名密碼輸入要訪問的數(shù)據(jù)庫的用戶名和密碼就行了
