在11gr2中,用exp导出数据时,发现新表里如果有数据才能导出来,没有数据就导不出来,所以有下面的方法实现
expdp system/******** dumpfile=dd.dmp schemas=USR reuse_dumpfiles=true nologfile=true
impdp system/******** dumpfile=dd.dmp remap_schema=USR:USR nologfile=true
C:\Documents and Settings\dell>expdp system/oracle file=dd.dmp owner=USR

由于以下参数, 旧有模式处于活动状态:
旧有模式参数: "file=dd.dmp" 位置: Command Line, 替换为: "dumpfile=dd.dmp"
旧有模式参数: "owner=USR" 位置: Command Line, 替换为: "schemas=USR"
旧有模式设置了 reuse_dumpfiles=true 参数。
旧有模式设置了 nologfile=true 参数。
启动 "SYSTEM"."SYS_EXPORT_SCHEMA_01": system/******** dumpfile=dd.dmp schemas=U
SR reuse_dumpfiles=true nologfile=true
