代码示例

DeleteCodedValueFromDomain 示例 1（Python 窗口）

以下 Python 窗口脚本演示了如何在即时模式下使用 DeleteCodedValueFromDomain 函数。

import arcpy
arcpy.env.workspace =  "C:/data"
arcpy.DeleteCodedValueFromDomain_management("montgomery.gdb", "DistDiam", ["20","24"])

DeleteCodedValueFromDomain 示例 2（独立脚本）

此独立脚本将 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
# Import system modules
import arcpy
import os
 
# Set the workspace (to avoid having to type in the full path to the data every time)
arcpy.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, 
                               os.path.join(dWorkspace, 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
