ArcGIS批量修改字段名称或类型

ArcPy就和ArcObjects，强大得令人发指，呵呵，开个玩笑！
在实际工作中会碰到这样的需求，shape file or geodatabase的feature class的字段名和字段类型不是我们想要的，可是通过ArcGIS的软件或者数据库本身都没法去修改它。怎么办，ArcPy可以显身手了。
- import arcpy
- from arcpy import env
- # use your own
- env.workspace = “”
- # use your own
- outpath = “”
- fcList = arcpy.ListFeatureClasses()
- for infc in fcList:
- outfc = infc
- print “in featureclass : “ + infc + ” out featureclass : “ + outfc
- fieldmappings = arcpy.FieldMappings()
- infields = arcpy.ListFields(infc)
- for infield in infields:
- if infield.name == “OBJECTID” or infield.name == “shape” or infield.name == “Shape”:
- continue
- fieldmap = arcpy.FieldMap()
- fieldmap.addInputField(infc, infield.name)
- outname = infield.name
- outfield = fieldmap.outputField
- outfield.name = outname.upper()
- # if you want to change field type use :
- # outfield.type = “”
- fieldmap.outputField = outfield
- fieldmappings.addFieldMap(fieldmap)
- print “add field map “ + infield.name + ” – “ + outfield.name
- del fieldmap, outfield
- print “start to copy ……”
- arcpy.FeatureClassToFeatureClass_conversion(infc, outpath, outfc, “”, fieldmappings)
-
print “done”
