Remove Domain From Field

Summary

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.

Syntax

ParameterExplanationData Type
in_table

Table View
field_name

The field that will no longer be associated with an attribute domain.

Field
subtype_code
[subtype_code,...]
(Optional)

The subtype code(s) that will no longer be associated with an attribute domain.

String

Code sample

RemoveDomainFromField example 1 (Python window)

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

import arcpy
arcpy.env.workspace = "C:/data"
arcpy.RemoveDomainFromField_management("montgomery.gdb/water/distribmains", "DIAMETER")
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.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
