5.expdp impdp中 exclude/include 的使用

轉載自：https://blog.csdn.net/leshami/article/details/7034839

exclude和include參數能夠在使用expdp或impdp是對特定的對象或對象類型進行篩選或過濾。比如因工作的需要導出特定的表或不導出特定
的表、視圖以及存儲過程、索引、約束、授權統計信息等等。下面將給出expdp或impdp使用exclude和include參數的方法和示例。

一、exclude/include參數用法：

EXCLUDE=[object_type]:[name_clause],[object_type]:[name_clause]  -->排出特定對象
INCLUDE=[object_type]:[name_clause],[object_type]:[name_clause]  -->包含特定對象
object_type子句用於指定對象的類型，如table,sequence,view,procedure,package等等
name_clause子句可以為SQL表達式用於過濾特定的對象名字。它由SQL操作符以及對象名(可使用通配符)來過濾指定對象類型中的特定對象。
當未指定name_clause而僅僅指定object_type則所有該類型的對象都將被過濾或篩選。多個[object_type]:[name_clause]中間以逗號分割。
示例：
expdp <other_parameters> SCHEMAS=scott EXCLUDE=SEQUENCE,TABLE:"IN ('EMP','DEPT')"
impdp <other_parameters> SCHEMAS=scott INCLUDE=PACKAGE,FUNCTION,PROCEDURE,TABLE:"='EMP'"

二、常用的過濾SQL表達式

EXCLUDE=SEQUENCE,VIEW                          	--過濾所有的SEQUENCE,VIEW  
EXCLUDE=TABLE:"IN ('EMP','DEPT')"               --過濾表對象EMP,DEPT  
EXCLUDE=SEQUENCE,VIEW,TABLE:"IN ('EMP','DEPT')" --過濾所有的SEQUENCE,VIEW以及表對象EMP,DEPT  
EXCLUDE=INDEX:"= 'INDX_NAME'"                   --過濾指定的索引對象INDX_NAME  
INCLUDE=PROCEDURE:"LIKE 'PROC_U%'"              --包含以PROC_U開頭的所有存儲過程(_ 符號代表任意單個字符)  
INCLUDE=TABLE:"> 'E' "                          --包含大於字符E的所有表對象
其它常用操作符 NOT IN, NOT LIKE, <, != 等等
直接將過濾操作符封裝到參數文件中，如下面的例子
Parameter file:exp_scott.par

DIRECTORY = dump_scott
DUMPFILE = exp_scott_%U.dmp
LOGFILE = exp_scott.log
SCHEMAS = scott
PARALLEL= 2
EXCLUDE = TABLE:"IN ('EMP', 'DEPT')" 

expdp system/manager parfile=exp.par

三、命令行下轉義符的處理

--Windows平台:
D:\> expdp system/manager DIRECTORY=my_dir DUMPFILE=exp_tab.dmp LOGFILE=exp_tab.log SCHEMAS=scott INCLUDE=TABLE:\"IN ('EMP', 'DEPT')\"

在Windows平台下，需要對象雙引號進行轉義，使用轉義符\]

--Unix平台:
在未使用parfile文件的情形下，所有的符號都需要進行轉義，包括括號，雙引號，單引號等
% expdp system/manager DIRECTORY=my_dir DUMPFILE=exp_tab.dmp LOGFILE=exp_tab.log SCHEMAS=scott INCLUDE=TABLE:\"IN \(\'EMP\', \'DEP\'\)\" 

四、exclude/include常見的錯誤

任意需要轉義的字符如果未轉義或轉義錯誤，都會產生ORA錯誤。下面給出幾種常見的ORA錯誤。

ORA-39001: invalid argument value
ORA-39071: Value for INCLUDE is badly formed.
ORA-00936: missing expression
ORA-39001: invalid argument value
ORA-39071: Value for EXCLUDE is badly formed.
ORA-00904: “DEPT”: invalid identifier
ORA-39001: invalid argument value
ORA-39041: Filter “INCLUDE” either identifies all object types or no object types.
ORA-39001: invalid argument value
ORA-39041: Filter “EXCLUDE” either identifies all object types or no object types
ORA-39001: invalid argument value
ORA-39038: Object path “USER” is not supported for TABLE jobs.

五、導出示例

-->導出不包含sequence，表EMP，DEPT的其它所有對象
  [oracle@orasrv scott]$ expdp scott/tiger directory=dump_scott dumpfile=fliter_1.dmp log=fliter_1.log schemas=scott \
  > exclude=sequence,table:\" in \(\'EMP\',\'DEPT\'\)\"
-->包含大於字符T的所有表對象
  [oracle@orasrv ~]$ expdp scott/tiger directory=dump_scott dumpfile=tmp.dmp logfile=tmp.log include=table:\"\>\'T\'\"

-->僅僅導入表對象TT，如果存在則將其替換
    [oracle@orasrv scott]$ impdp scott/tiger directory=dump_scott dumpfile=tmp.dmp logfile=tmp_imp.log \

-->下面是一個實際實際導出過程中的parfile參數,exclude參數用於排出所有包含BAK的表對象,以及一些索引對象,使用了in,like運算符
    userid=goex_admin
    directory=DB_DUMP_DIR
    dumpfile=sybo2_full_%U.dmp
    logfile=sybo2_full.log
    exclude=table:"like '%BAK%'",index:" in ('PK_ACC_POS_CASH_PL_TBL_ARC_11','pk_acc_pos_cash_tbl_arc_11',
     'PK_ACC_POS_STOCK_ARCH_TBL_11','I_ACC_POS_STOCK_TBL_ARC_DT','I_ACC_POS_CASH_PL_ARCH_TBL_DT') ",
     table:"in ('ACC_POS_STOCK_TBL_ARC')"

 -->下面是一個使用query查詢過濾的情形
  -->該操作導出的schema為scott，表對象emp中deptno=20，以及dept表中deptno=20的記錄被導出，這兩個表中的其余記錄被過濾
  -->該操作除上述過濾以后的所有對象將被一一導出
  expdp scott/tiger dumpfile=scott_filter.dmp logfile=scott_filter.log directory=DB_DUMP_DIR schemas=scott \
  > query=scott.emp:'"where deptno=20"',scott.dept:'"where deptno=20"'
