今天在导数据时出现  ORA-39151: Table "CX"."CX_CXZL" exists. All dependent metadata and data will be skipped due to table_exists_action of skip的错误，在导入语句的后面已经加了 TABLE_EXISTS_ACTION=TRUNCATE，为什么还是table存在，然后跳过呢！！

仔细观察，发现我的语句被分成了两半，实际上   ORA-39151是由上一半产生的， impdp system/11123  DIRECTORY=DP_DIR dumpfile=20141119_cx_NHLTGN.dmp logfile=imp20141119_cx_NHLTGN.log  而后一半则在后面无法识别执行。。可能是tables之前多了回车，将tables 往前移动就解决问题了

gdstdb01:/home/oracle$impdp system/11123 DIRECTORY=DP_DIR dumpfile=20141119_cx_NHLTGN.dmp logfile=imp20141119_cx_NHLTGN.log
