How to Export or Import Case Sensitive Tables Without Using a Par File (Doc ID 1622134.1)1
適用於:
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.
目標:
在不使用par file的情況下,export or import 含有大小寫表名的表
解決方案:
含有大小寫表名的表可以使用帶有par file的expdp ,但是,從命令列進行exp的話,所需要的雙引號需要轉義(escaped)
下面的例子說明了使用含有大小寫表名的表的方法。
建立測試表:
connect / as sysdba
create use test identified by test;
grant connect, resource, dba to test;
create table test."TEst" as select * from dba_users;
用下面的命令匯出表:
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"

為了成功的export出表,你必須轉義雙引號。
expdp test/test directory=DATA_PUMP_DIR dumpfile=a.dmp tables=test.\"TEst\"
