一、問題描述

       有個小小需求，要從生產數據庫上導數據到測試庫，問題是有張大表（30G）不需要導出到測試環境，所以要使用到expdp中’exclude’參數。但是在使用過程中還是碰到一點點question。

二、操作過程

1.根據expdp -help 信息中得知exclude參數的for example如下：

EXCLUDE                                

Exclude specific object types.         

For example, EXCLUDE=SCHEMA:"='HR'”.     

當然 = 也可以替換成 in ( ) 或 like ‘%..%’這種方式，如：exclude=index:”like ‘emp%’" ，也可以只給object types，如: exclude=VIEW,PACKAGE, FUNCTION

官方文檔給出的Syntax是

EXCLUDE=object_type[:name_clause] [, …]

按照上面的例子，我推斷出exclude參數針對表的使用

exclude=table:”=‘table name’”

2.執行語句報錯，此處說明語法有問題，最終查詢到原來是由于沒有加轉義符。

[oracle@rac2 ~]$ expdp cloan/xxxx DIRECTORY=backup DUMPFILE=cloan_20170713.dmp log=cloan_20170713.log  exclude=table:"='WSCT_DATA'" compression=all

LRM-00116: syntax error at 'table:' following '='

3.修改，增加轉義符后執行成功

[oracle@rac2 ~]$ expdp cloan/xxxx DIRECTORY=backup DUMPFILE=cloan_20170713.dmp log=cloan_20170713.log  EXCLUDE=TABLE:\"= \'WSCT_DATA\'\" compression=all
