[转]Sqlplus 登录数据库

1.直接敲sqlplus并回车就是启动SQL*PLUS，输入user及password将使用户登陆到缺省的数据库

C:\Documents and Settings\Administrator>sqlplus

SQL*Plus: Release 9.2.0.1.0 - Production on

Copyright (c) 1982, 2002, Oracle Corporation.  All rights reserved.

请输入用户名:

2.sqlplus user/password@SERVICE_NAME将连接到指定的数据库

C:\Documents and Settings\Administrator>sqlplus dbusername/password@SERVICE_NAME
SQL*Plus: Release 9.2.0.1.0 - Production on

Copyright (c) 1982, 2002, Oracle Corporation.  All rights reserved.

连接到:
Oracle9i Enterprise Edition Release 9.2.0.1.0 - Production
With the Partitioning, OLAP and Oracle Data Mining options
JServer Release 9.2.0.1.0 - Production

3.但如果敲 sqlplus /nolog就是使SQL*PLUS启动,但不登陆Oracle数据库。然后需要使用connect命令连接Oracle

C:\Documents and Settings\Administrator>sqlplus /nolog

SQL*Plus: Release 9.2.0.1.0 - Production on

SQL> connect dbusername/password@SERVICE_NAME
已连接。
