整理Python代码：

 import arcpy, os, string,sys
 reload(sys)
 sys.setdefaultencoding( "utf-8" )

 def CopyDatasets(start_db,end_db,num):
     try:
         #Set workspaces
         arcpy.env.workspace = start_db
         wk2 = end_db
         datasetList = arcpy.ListDatasets()
         #for feature classes within datasets
         for dataset in datasetList:
             print "Reading: {0}".format(dataset)
             name = arcpy.Describe(dataset)
             new_data=name.name[num:]
             if (not arcpy.Exists(wk2 + os.sep + new_data)):
                 arcpy.Copy_management(dataset, wk2 + os.sep + new_data)
                 print "Completed copy on {0}".format(new_data)
             else:
                 print "Dataset {0} already exists in the end_db so skipping".format(new_data) #如果有同名的就Skip
         #Clear memory
         del dataset
     except Exception as e:
         arcpy.AddError(e.message)

 def CopyFeatureClasses(start_db,end_db,num):
     try:
         #Set workspaces
         arcpy.env.workspace = start_db
         wk2 = end_db
         datasetList = arcpy.ListDatasets()
         #for feature classes within datasets
         for fc in arcpy.ListFeatureClasses():
             print "Reading: {0}".format(fc)
             name = arcpy.Describe(fc)
             new_data=name.name[num:]
             if arcpy.Exists(wk2 + os.sep + new_data)==False:
                 arcpy.Copy_management(fc, wk2 + os.sep + new_data)
                 print "Completed copy on {0}".format(new_data)
             else:
                 print "Feature class {0} already exists in the end_db so skipping".format(new_data)
         #Clear memory
         del fc
     except Exception as e:
         arcpy.AddError(e.message)

 def CopyTables(start_db,end_db,num):
     try:
     #Set workspaces
         arcpy.env.workspace = start_db
         wk2 = end_db
         datasetList = arcpy.ListDatasets()
         #for feature classes within datasets
         for table in arcpy.ListTables():
             print "Reading: {0}".format(table)
             name = arcpy.Describe(table)
             new_data=name.name[num:]
             if arcpy.Exists(wk2 + os.sep + new_data)==False:
                 arcpy.Copy_management(table, wk2 + os.sep + new_data)
                 print "Completed copy on {0}".format(new_data)
             else:
                 print "Table {0} already exists in the end_db so skipping".format(new_data)
         #Clear memory
         del table
     except Exception as e:
         arcpy.AddError(e.message)

 if __name__== "__main__":
     start_db =r'C:\Users\nightroad\AppData\Roaming\ESRI\Desktop10.2\ArcCatalog\test.sde' #源工作空间
     end_db = r'E:\Test\Test.gdb'  #目的工作空间
     num =0                              # (例如: sde.sde. is 8)
     CopyDatasets(start_db,end_db,num)
     CopyFeatureClasses(start_db,end_db,num)
     CopyTables(start_db,end_db,num)  

Python脚本的目的就是将获得源工作空间和目的工作空间，里面有一个Num的选择，根据数据库不一样来记录要素类或者数据集前的字符串：
SQL Server：sde.sde.featureclass或者sde.dbo.featureclass
那么只记录sde.sde.(sde.dbo.)一共8个字符，num=8
Oracle：test.featureclass
那么只记录test.一共5个字符串,num=5
FileGDB，没有前缀，num=0
