代码实例

从属性域中删除编码值的示例(Python 窗口)

以下 Python 窗口脚本演示了如何在立即模式下使用 CreateDomain 函数。

import arcpy from arcpy import env env.workspace =  "C:/data" arcpy.DeleteCodedValueFromDomain_management("montgomery.gdb", "DistDiam", ["20","24"])
从属性域中删除编码值的示例 2(独立脚本)

该独立脚本将 DeleteCodedValueFromDomain 函数用作编辑属性域的工作流的一部分

# Name: RemoveDomainsExample.py # Purpose: Update an attribute domain to constrain valid pipe material values # Author: ESRI  # Import system modules import arcpy, os from arcpy import env   try:     # Set the workspace (to avoid having to type in the full path to the data every time)     env.workspace = "data"       # set local parameters     inFeatures = "Montgomery.gdb/Water/DistribMains"     inField = "MATERIAL"     dWorkspace = "Montgomery.gdb"     domName = "Material"     codedValue =  "ACP: Asbestos concrete"     codeField = "TYPE"     descField = "DESRIPT"     # Process: Remove the constraint from the material field     arcpy.RemoveDomainFromField_management(inFeatures, inField)       # Edit the domain values     # Process: Remove a coded value from the domain     arcpy.DeleteCodedValueFromDomain_management(dWorkspace, domName, codedValue)       # Process: Create a table from the domain to edit it with ArcMap editing tools     arcpy.DomainToTable_management(dWorkspace, domname, dWorkspace + os.sep + domname , codeField, descField)       # Process: Delete the domain     arcpy.DeleteDomain_management(dWorkspace, domName)       # Edit the domain table outside of geoprocessing     # and then bring the domain back in with the TableToDomain process   except Exception, e:     # If an error occurred, print line number and error message     import traceback, sys     tb = sys.exc_info()[2]     print "Line %i" % tb.tb_lineno     print e.message
