使用SQL*PLUS构建完美excel或html输出-数据库

　　本例通过简单示例，介绍通过sql*plus输出xls，html两种格式文件.

　　首先创建两个脚本:
　　1.main.sql
　　用以设置环境，调用具体功能脚本

　　2.功能脚本-get_tables.sql
　　为实现具体功能之脚本

　　通过这样两个脚本可以避免spool中的冗余信息.

　　示例如下:
　　1.main.sql脚本:

[oracle@jumper utl_file]$ more main.sql
set linesize 200
set term off verify off feedback off pagesize 999
set markup html on entmap ON spool on preformat off
spool tables.xls
@get_tables.sql
spool off
exit

　　2.get_tables.sql脚本:

[oracle@jumper utl_file]$ more get_tables.sql
select owner,table_name,tablespace_name,blocks,last_analyzed
from all_tables order by 1,2;

　　3.执行并获得输出:

[oracle@jumper utl_file]$ sqlplus "/ as sysdba" @main
