不再用par file如果是，export or import 包含大写和小写表名称表



参考原始：

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 含有大写和小写表名的表



解决方式：



含有大写和小写表名的表能够使用带有par file的expdp ，可是，从命令行进行exp的话。所须要的双引號须要转义（escaped）



以下的样例说明了使用含有大写和小写表名的表的方法。





建立測试表：

connect / as sysdba

create use test identified by test;

grant connect, resource, dba to test;

create table test."TEst" as select * from dba_users;





用以下的命令导出表：

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，你必须转义双引號。

expdp test/test directory=DATA_PUMP_DIR dumpfile=a.dmp tables=test.\"TEst\"
