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"
