sqlplus的登录设置(glogin.sql)

[oracle@centos6 admin]$ pwd
/u01/app/oracle/product/11.2.0/sqlplus/admin
[oracle@centos6 admin]$ ls
glogin.sql  help  libsqlplus.def  plustrce.sql  pupbld.sql
[oracle@centos6 admin]$ cat glogin.sql
set feedback on  #显示当前sql语句查询或修改的行数
define _editor=vi #设置默认编辑器为vi
set serveroutput on size 1000000 #默认打开DBMS_OUTPUT，同时将默认缓冲池设置的尽可能大
set trimspool on #把输出内容每行后面多余的空格去掉
set long 5000  #设置选择LONG和CLOB列时显示的默认字节数
set linesize 200 #设置一行可以容纳的字节数
set pagesize 9999 #设置一页有9999行，将此参数设置的大写这样每页就只显示一次标题
column plan_plus_exp format a80 #设置autotrace得到解释细化输出的默认宽度，一般80足够放下整个计划
column global_name new_value gname #设置列的新名称
set termout off #屏幕上不显示所输出的信息
define gname=idle
column global_name new_value gname #设置sqlplus提示符，显示格式为用户@数据库名
select lower(user) || '@' || substr(global_name, 1, decode( dot, 0, length (global_name),
dot-1) ) global_name
from (select global_name,instr(global_name,'.') dot from global_name );
set sqlprompt '&gname> '
set termout on

使用效果：

scott@ORCL> select * from emp;
