Windows 安装完以后，默认输入SQL>
ed 则调出记事本，原因如下_EDITOR = "Notepad" SQL> define

DEFINE _DATE           = "23-11月-10" (CHAR)

DEFINE _CONNECT_IDENTIFIER = "win" (CHAR)

DEFINE _USER           = "SYS" (CHAR)

DEFINE _PRIVILEGE      = "AS SYSDBA" (CHAR)

DEFINE _SQLPLUS_RELEASE = "1002000100" (CHAR)

DEFINE _EDITOR         = "Notepad" (CHAR)

DEFINE _O_VERSION      = "Oracle Database 10g Enterprise
Edition Release 10.2.0.

1.0 - Production

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

DEFINE _O_RELEASE      = "1002000100" (CHAR)

DEFINE _RC             = "1" (CHAR) 而在Linux下默认则为 _EDITOR = "ed" (CHAR)，下面我们把默认的编辑器设置为vi或vim [oracle@rhel5 admin]$ vi $ORACLE_HOME/sqlplus/admin/glogin.sql

在文件的末尾添加DEFINE _EDITOR = "vi"或DEFINE _EDITOR   = "vim" 这样我们在使用sqlplus的ed命令时就可以调用vi或vim编辑器了。
