Code sample

Delete Coded Value from Domain Example (Python Window)

The following Python window script demonstrates how to use the CreateDomain function in immediate mode.

import arcpy
arcpy.env.workspace =  "C:/data"
arcpy.DeleteCodedValueFromDomain_management("montgomery.gdb", "DistDiam", ["20","24"])
Delete Coded Value from Domain Example 2 (Stand-alone Script)

This stand-alone script uses the DeleteCodedValueFromDomain function as part of a workflow to edit a domain

# Name:
# 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, 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
