Oracle修改提示符方法
sqlplus启动的时候会读取glogin.sql脚本，在$Oracle_HOME/sqlplus/admin目录中，写在里面就可以了。
给你个例子。

Welcome to Seraphim's SQL*PLUS!
You are connected to ORA921.IAGENT as SCOTT
SQL>;
实现这种效果，在glogin.sql中加入以下行：
set heading off
prompt Welcome to Seraphim's SQL*PLUS!
select 'You are connected to ' || global_name || ' as ' || user from global_name;
set serveroutput on
set heading on
或
COLUMN host_name new_value hname
SET TERMOUT OFF
select SYS_CONTEXT('USERENV','HOST') host_name from dual;
SET SQLPROMPT '&hname>;'
SET TERMOUT ON
