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

RemoveDomainFromField_management (in_table, field_name, {subtype_code})
ParameterExplanationData Type
in_table

The input table containing the attribute domain that will be removed.

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

Remove Domain from Field Example (Python Window)

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

import arcpy
from arcpy import env 
env.workspace = "C:/data"
arcpy.RemoveDomainFromField_management("montgomery.gdb/water/distribmains", "DIAMETER")
Remove Domain from Field 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, os
 
try:
    # 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
 
except Exception as err:
    print(err.args[0])
