说明：ORACLE10G 以后解决这个问题更方便，使用exclude include。用法如下：

EXCLUDE = object_type[:name_clause][,…]

INCLUDE = object_type[:name_clause][,…]

例如：

Expdp <other_paramters> SCHEMAS=XZSP EXCLUDE=SEQUENCE,INDEX,TABLE:”LIKE %EMP”

IMpdp <other_paramters> SCHEMAS=XZSP INCLUDE=FUNCTION,PACKAGE,PROCEDUGE ,TABLE:”IN (‘EMP’,’DEMP’)”

Linux下使用需要使用转义字符“”,当然最好使用参数文件

############定义参数文件parfile.par ##############

Directory=expdir

Schemas=rman

Dumpfile=expdp_rman.dmp

Include=TABLE:”IN(‘DB’,’TS’)”

执行导出命令如下

Expdp ’/ as sysdba ’ parfile.par
