导入数据IMP-00058 ORA-00904

将源库分区表数据迁移到历史库中碰到IMP-00058 ORA-00904错误，具体操作及解决如下：

\'/ as sysdba\' statistics=nonedata_only=y file=/backup/wxlun20130911.dmplog=/backup/wxlun20130911.implog fromuser=wxlun touser=wxlun_his buffer=5400000

表wxlun_t02分区数据导入成功，而wxlun_t01导入失败，查看目的库的wxlun_t01表结构
sys@wxlun_his>desc wxlun.wxlun_t01
name null? type
------------------------------------------------- ----------------------------
bcid not null varchar2(20)
formcode not null varchar2(50)
currentstatus not null number(3)
prestatus not null number(3)
returnstatus number(3)

currentdistributioncode not null varchar2(50)

源库wxlun_t01表结构
sys@wxlun:sql>desc wxlun.wxlun_t01
name null? type
-------------------------------------------------------------------------------- -------------------------------------------------
bcid not null varchar2(20)
formcode not null varchar2(50)
currentstatus not null number(3)
prestatus not null number(3)
returnstatus number(3)
operatetype not null number(5)
currentdistributioncode not null varchar2(50)
deliverstationid not null number(10)
note not null varchar2(400)
createby not null number(10)
createdept not null number(10)
createtime not null date
isdeleted not null number(1)
syncflag not null number(1)
synctime date
ipaddress varchar2(20)
clientinfo varchar2(2000)
todistributioncode varchar2(100)
toexpresscompanyid number

发现源库的表增加了两个字段(随着业务需要，某些表会增加字段)，将目的库表添加相应字段，，并将导入失败的表数据重新导入：

sys@wxlun_his>alter table wxlun.wxlun_t01 add todistributioncodevarchar2(100);
alter table wxlun.wxlun_t01 add toexpresscompanyid number;

table altered.

sys@wxlun_his>
table altered.
