Oracle:Sqlplus提示符sqlprompt

 在sqlplus里打入set sqlprompt _user"@"_conect_identifier">" 这只是临时有效;

在$ORACLE_HOME/sqlplus/admin/global.sql里加入上一句话,提示符将永久有效。

 

 

当管理的数据库比较多的时候,在sqlplus里切换就是一件麻烦的事。 要非常小心,以防出错。 可以修改sqlplus 的提示符:SQL> ,把这个改成我们用户和实例名,这样就不容易出错。

先看一下Oracle 自定义的参数:

SQL> define

DEFINE _DATE = "11-MAY-11" (CHAR)

DEFINE _CONNECT_IDENTIFIER = "dave1" (CHAR)

DEFINE _USER = "SYS" (CHAR)

DEFINE _PRIVILEGE = "AS SYSDBA" (CHAR)

DEFINE _SQLPLUS_RELEASE = "1002000100" (CHAR)

DEFINE _EDITOR = "ed" (CHAR)

DEFINE _O_VERSION = "Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - Production

With the Partitioning, Real Application Clusters, OLAP and Data Mining options" (CHAR)

DEFINE _O_RELEASE = "1002000100" (CHAR)

 

 

我们可以使用这些定义的参数来设定相关信息,也可以使sql 来拼接显示的信息。 如:

SQL> set sqlprompt "_USER@ _CONNECT_IDENTIFIER >"

SYS@ dave1 >

但是这个方式在sqlplus 关闭之后就没有了。 要想永久的保存,就需要修改配置文件glogin.sqlsqlplus 在启动时,会读取该文件。 该文件位置:

$ORACLE_HOME/sqlplus/admin/glogin.sql

方法一:

 

$ORACLE_HOME/sqlplus/admin/glogin.sql 文件里添加如下参数:

set sqlprompt "_USER@ _CONNECT_IDENTIFIER >"

然后打开sqlplus

[oracle@rac1 admin]$ sqlplus / as sysdba;

SYS@ dave1>

 

 

方法二: 使用sql 语句拼接

 

$ORACLE_HOME/sqlplus/admin/glogin.sql 文件里添加如下参数:

set time on

set termout off -- 如果不加这句,每次都会显示下面查询的select 结果集
column propmt_q new_value propmt_q
select upper(user)||'@'|| instance_name||'('||host_name||')' as propmt_q from v$instance;
set sqlprompt '&propmt_q> '

 

在打开sqlplus,效果如下:

[oracle@rac1 admin]$ sqlplus / as sysdba;

 

SQL*Plus: Release 10.2.0.1.0 - Production on Wed May 11 18:50:27 2011

18:50:27 SYS@dave1(rac1)>select sysdate from dual;

 

SYSDATE

---------

11-MAY-11

 

18:51:27 SYS@dave1(rac1)>

 

 

 

把时间去掉:

set termout off -- 如果不加这句,每次都会显示下面查询的select 结果集

column propmt_q new_value propmt_q
select upper(user)||'@'|| instance_name||'('||host_name||')' as propmt_q from v$instance;
set sqlprompt '&propmt_q> '

 

 

[oracle@rac1 admin]$ sqlplus / as sysdba;
