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.management.DeleteCodedValueFromDomain("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.management.RemoveDomainFromField(inFeatures, inField)
# Edit the domain values
# Process: Remove a coded value from the domain
arcpy.management.DeleteCodedValueFromDomain(dWorkspace, domName, codedValue)
# Process: Create a table from the domain to edit it with ArcGIS Pro editing tools
arcpy.management.DomainToTable(dWorkspace, domname,
os.path.join(dWorkspace, domname), codeField,
descField)
# Process: Delete the domain
arcpy.management.DeleteDomain(dWorkspace, domName)
# Edit the domain table outside of geoprocessing
# and then bring the domain back in with the TableToDomain process
