oracle 卸载数据，tom的脚本

本文主要是介绍oracle 卸载数据，tom的脚本，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

oracle  卸载数据，tom的脚本，可以修改一下，做到自己想要的

--1.导出数据

[oracle@localhost ~]$ more flat.sh 
#!/bin/shif [ "$1" = "" ]
thencat << EOF
editor: mengl  2016-5-26
usage:          flat un/pw [tables|views]example:        flat scott/tiger emp deptdescription:    Select over standard out all rows of table or view withcolumns delimited by tabs.
EOFexit
fiPW=$1
shiftfor X in $*
do
sqlplus -s $PW << EOF > /tmp/flat$$.sql
set     wrap off
set     feedback off
set     pagesize 0
set     verify off
prompt  select
select  lower(column_name)||'||chr(9)||'
from    user_tab_columns
where   table_name = upper('$X') andcolumn_id != (select max(column_id) from user_tab_columns wheretable_name = upper('$X'))
order by column_id
/
select  lower(column_name)
from    user_tab_columns
where   table_name = upper('$X') andcolumn_id = (select max(column_id) from user_tab_columns wheretable_name = upper('$X'))
order by column_id
/
prompt  from    $X
prompt  /
prompt  exit
exit
EOF
sqlplus -s $PW << EOF
set     wrap off
set     feedback off
set     pagesize 0
set     verify off
set trimspool on
set linesize 5000
start /tmp/flat$$.sql
exit
EOF
#rm /tmp/flat$$.sql
done
[oracle@localhost ~]$ 

--导出数据样例

[oracle@localhost ~]$ ./flat.sh unicomidmp/broadtech ml_2 >1.txt
[oracle@localhost ~]$ more 1.txt 
103	10305	GD-WL-SG-XFX-C类-新丰沙田网格-190	236	113.883073	24.054267	1
[oracle@localhost ~]$ 

--这样，就可以导出文本文件1.txt, 共sqlldr加载。
