Removes an attribute domain association from a feature class or table field.
Usage
This tool is the opposite operation from the Assign Domain To Field function. Removing a domain from a field removes the association between a field and an attribute domain.
When a domain is removed from a field, the attribute validation rule for that field is removed from the database.
The same attribute domain can be associated with multiple fields of the same table, feature class, or subtype as well as with multiple tables and feature classes. Removing a domain from a field will not affect other domain associations.
Current map layers may be used to define the Input table.
RemoveDomainFromField example 2 (stand-alone script)
This stand-alone script uses the RemoveDomainFromField function as part of a workflow to edit a domain.
# 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 ArcMap 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
