Oracle SQL*Plus 数据备份为 sql 文件

在某些比较严格的环境中，不提供像PL/SQL Developer 这样的工具供我们备份表数据时，使用SQL*Plus运行如下脚本内容导出数据.

1,  执行时登录SQL*Plus，  命令   @D:/backup.sql

2, backup.sql 文件内容：

-- 备份权限表数据--
set echo off
set feedback off
set newpage none
set pagesize 5000
set linesize 500
set verify off
set pagesize 0
set term off
set trims on
set linesize 600
set heading off
set timing off
set verify off
set numwidth 38
SPOOL c:\xxx.sql   -- 指定的导出文件路径

---------------------------具体要导出的sql---------可以写任意多条sql语句----------------------

-------------back base_permission----------------start---

select 'insert into BASE_PERMISSION (permis_id, permis_code, permis_name, permis_url, permis_order, remark, permis_pid, belong, creator, gmt_create, modifier, gmt_modified, permis_type)
values (' || b.permis_id ||',' ||
chr() ) ||','||
chr() ) ||','||
chr() ) ||',' ||
b.permis_order ||','||
) ) end || ',' ||
b.permis_pid ||','||
) ) end || ',' ||
b.creator ||','||
))) ) || ')' || ',' ||
b.modifier||','||
))) ) || ')' || ',' ||
chr() ) ||
');'
from BASE_PERMISSION b;
-------------back base_permission----------------end---

------------------继续导出其它表-----------------

SPOOL OFF

上面脚本仅仅导出了权限表数据，导出的最终内容如下：

insert into BASE_PERMISSION (permis_id, permis_code, permis_name, permis_url, permis_order, remark, permis_pid, belong, creator, gmt_create, modifier, gmt_modified, permis_type)
,,,,to_date(,to_date(');

insert into BASE_PERMISSION (permis_id, permis_code, permis_name, permis_url, permis_order, remark, permis_pid, belong, creator, gmt_create, modifier, gmt_modified, permis_type)
,,,,to_date(,to_date(');

insert into BASE_PERMISSION (permis_id, permis_code, permis_name, permis_url, permis_order, remark, permis_pid, belong, creator, gmt_create, modifier, gmt_modified, permis_type)
,,,,to_date(,to_date(');

insert into BASE_PERMISSION (permis_id, permis_code, permis_name, permis_url, permis_order, remark, permis_pid, belong, creator, gmt_create, modifier, gmt_modified, permis_type)
,,,,to_date(,to_date(');

insert into BASE_PERMISSION (permis_id, permis_code, permis_name, permis_url, permis_order, remark, permis_pid, belong, creator, gmt_create, modifier, gmt_modified, permis_type)
,,,,to_date(,to_date(');

insert into BASE_PERMISSION (permis_id, permis_code, permis_name, permis_url, permis_order, remark, permis_pid, belong, creator, gmt_create, modifier, gmt_modified, permis_type)
,,,,to_date(,to_date(');

insert into BASE_PERMISSION (permis_id, permis_code, permis_name, permis_url, permis_order, remark, permis_pid, belong, creator, gmt_create, modifier, gmt_modified, permis_type)
,,,,to_date(,to_date(');

insert into BASE_PERMISSION (permis_id, permis_code, permis_name, permis_url, permis_order, remark, permis_pid, belong, creator, gmt_create, modifier, gmt_modified, permis_type)
,,,,to_date(,to_date(');
