通過SQL*PLUS我們可以構建友好的輸出，滿足多樣化用戶需求。
本例通過簡單示例，介紹通過sql*plus輸出xls，html兩種格式文件.
首先創建兩個腳本:
1.main.sql
用以設置環境，調用具體功能腳本
2.功能腳本-get_tables.sql
為實現具體功能之腳本
通過這樣兩個腳本可以避免spool中的冗余信息.
示例如下:
1.main.sql腳本:
[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腳本:
[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.執行並獲得輸出:
[oracle@jumper utl_file]$ sqlplus "/ as sysdba" @main
