设置SQL PLUS环境

参考Oracle Database 9i/10g/11g编程艺术一书：

login.sql代码如下：

define _editor=vi
set serveroutput on size 1000000
set trimspool on
set long 5000
set linesize 700
set pagesize 9999
column plan_plus_exp format a80
column global_name new_value gname
set termout off
define gname=idle
column global_name new_value gname
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

win7  oracle环境变量 SQLPATH 在注册表中：

HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE\KEY_OraDb11g_home1\SQLPATH

"SQLPATH"="E:\\MyOracle\\oracle\\product\\11.2.0\\dbhome_1\\dbs"

将login.sql 放在SQLPATH指定目录下，然后重新执行sql plus即可：

C:\>sqlplus / as sysdba

sql plus提示符变为：

sys@orcl>
