oracle--EXPDP 指定排除某些表

其他 2021-03-22 08:13:45 阅读次数: 0

使用逻辑工具的EXCLUDE选项可以指定那类不被导出，EXPDP工具的前身EXP如果想要完成同样的任务非常的困难。我们以部分表为例看一下这个带给我们的便利。

如果在命令行中完成备份，特殊字符的转义需要特别注意（我这里使用的是Linux操作系统）。

该用户下有四张表

yhzx@MYTEST>select * from cat;

TABLE_NAME TABLE_TYPE

T1_SAFE TABLE

TTT TABLE

T_PLATFORM_USER TABLE

T_PLATFORM_USER_SAFE TABLE

UID_SEQ SEQUENCE

USERCODE_SEQ SEQUENCE

6 rows selected.

全部备份：

备份多用户，排除多个表

下边，用system备份了yhzx、scott两个用户，排除了yhzx下的TTT和T1_SAFE两张表

[oracle@wg2 app]$ expdp system/oracle@mytest directory=exp schemas=yhzx,scott dumpfile=ss-yhzx-ttt-safe.dmp logfile=ss-yhzx-ttt-safe.log EXCLUDE=TABLE:“IN(‘TTT’,‘T1_SAFE’)”

– 导出yhzx用户下排除T_PLATFORM开头的所有表：
