在不使用par file的情况下，export or import 含有大小写表名的表

参考原文：
How to Export or Import Case Sensitive Tables Without Using a Par File (Doc ID 1622134.1)1

适用于：
Oracle Database - Enterprise Edition - Version 10.2.0.1 to 11.2.0.4 [Release 10.2 to 11.2]
Information in this document applies to any platform.


目标：

在不使用par file的情况下，export or import 含有大小写表名的表

解决方案：

含有大小写表名的表可以使用带有par file的expdp ，但是，从命令行进行exp的话，所需要的双引号需要转义（escaped）

下面的例子说明了使用含有大小写表名的表的方法。


建立测试表：
connect / as sysdba
create use test identified by test;
grant connect, resource, dba to test;
create table test."TEst" as select * from dba_users;


用下面的命令导出表：
expdp test/test directory=DATA_PUMP_DIR dumpfile=a1.dmp tables=TEST."TEst"


expdp test/test directory=DATA_PUMP_DIR dumpfile=a1.dmp tables=TEST."TEst"

为了成功的export出表，你必须转义双引号。
expdp test/test directory=DATA_PUMP_DIR dumpfile=a.dmp tables=test.\"TEst\"
