Shape文件入库

请教：我从SDE数据库中导出shape文件,删除库中内容,再将其重新入库,系统却提示如下问题:

D:\>shp2sde -o append -l sde.AreaBourn_010,shape -f   C:\temp\AreaBourn_010.shp -  a all -i 5151:esri_sde -u sde -p sde -s KC003

Shape file and layer attribute schemas are not compatible.
Problem processing Shape attribute column:
Name Type Width Decimal Places
------------ ---- ----- --------------
SHAPE_AREA F 19 11
Shape attribute to SDE column specification string:
"Spatial_Col integer, CODE string(6), PAC string(8), NAME string(40), MAPNUMB string(10), MAPLEVE string(20), MAPDATE date, SHAPE_AREA double(30,11), SHAPE_LEN double(30,11)"

假如通过ArcCatalog却可以将刚才导出的Shape文件入库,请问是何原因???
谢谢!!
