ORACLE 分区后dmp导入报错：imp-00058 遇到oracle错误 14400?报错

oralce数据库表分区创建后，在导入dmp文件时报错：

imp-00058 遇到oracle错误 14400

ORA-14400: inserted partition key does not map to any partition

自己百度了一下，貌似是导入的数据找不到适合自己的分区。

表分区创建的代码：

create table ZB_FXDATA
(
  YEARS            VARCHAR2(40),
  MONTHS           VARCHAR2(40),
  C_UNITNO         VARCHAR2(100),
  C_UNITSHORTNAME  VARCHAR2(50),
  C_CLASSNO        VARCHAR2(20),
  C_BUSINESSNAME   VARCHAR2(30),
  ZB_ACCOUNTNO     VARCHAR2(15),
  ZB_ACCOUNTNAME   VARCHAR2(255),
  N_YEARTOTAL      NUMBER,
  N_UPYEARTOTAL    NUMBER,
  N_MONTHAMOUNT    NUMBER,
  N_UPMONTHAMOUNT  NUMBER,
  C_BUSINESSNO     VARCHAR2(3),
  N_YEARTOTAL_SR   NUMBER,
  N_MONTHAMOUNT_SR NUMBER
)
 partition by range (MONTHS)
   (partition ZB_FXDATA_PT_09 values  less than ('10')   tablespace MONTH09,
   partition ZB_FXDATA_PT_10 values  less than ('11')   tablespace MONTH10,
   partition ZB_FXDATA_PT_11 values  less than ('12')   tablespace MONTH11,
   partition ZB_FXDATA_PT_12 values  less than ('13')   tablespace MONTH12,
   partition ZB_FXDATA_PT_01 values  less than ('2')   tablespace MONTH01,
   partition ZB_FXDATA_PT_02 values  less than ('3')   tablespace MONTH02,
   partition ZB_FXDATA_PT_03 values  less than ('4')   tablespace MONTH03,
   partition ZB_FXDATA_PT_04 values  less than ('5')   tablespace MONTH04,
   partition ZB_FXDATA_PT_05 values  less than ('6')   tablespace MONTH05,
   partition ZB_FXDATA_PT_06 values  less than ('7')   tablespace MONTH06,
   partition ZB_FXDATA_PT_07 values  less than ('8')   tablespace MONTH07,
   partition ZB_FXDATA_PT_08 values  less than ('9')   tablespace MONTH08
   );

我也参考了网上的一篇文章：http://blog.itpub.net/15112866/viewspace-442689/

里面也提到了一种开启 ROW MOVEMENT方法，我尝试了不行，应该不是这个问题。

既然是找不到合适自己的分区，我觉得应该是less than后面的问题，请大家指教一下！
