1、设置输出
SQL>set serveroutput on
这样每次输入会显得相当麻烦，一劳永逸办法如下
2、设置login.sql脚本，然后设置SQLPATH变量
login.sql内容参考如下：
define _editor=vi
set serveroutput on size 1000000
set trimspool on
set long 5000
set linesize 100
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
然后设置SQLPATH变量位login.sql所在的脚本即可
