Domain To Table


Creates a table from an attribute domain.


  • Creating a table from an attribute domain allows for additional editing of the table. For example, a table could be created from a coded value domain, additional code values could be added to the coded value list, and the Table To Domain tool could be used to update the original domain.

  • You can also manage domains in Domains view which can be opened by clicking the Domains button found in the Design group on the Data ribbon.


DomainToTable_management (in_workspace, domain_name, out_table, code_field, description_field, {configuration_keyword})
ParameterExplanationData Type

The workspace containing the attribute domain to be converted to a table.


The name of the existing attribute domain.


The table to be created.


The name of the field in the created table that will store code values.


The name of the field in the created table that will store code value descriptions.


For geodatabase tables, the custom storage keywords for creating the table.


Code sample

Domain to Table Example (Python Window)

The following Python window script demonstrates how to use the DomainToTable function.

import arcpy
arcpy.env.workspace = "C:/data"
arcpy.DomainToTable_management("montgomery.gdb", "DistDiam", "diameters", "code", "descript")
Domain to Table Example 2 (Stand-alone Script)

This stand-alone script uses the DomainToTable 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 = "C:/data"
    # set local parameters
    inFeatures = "Montgomery.gdb/Water/DistribMains"
    inField = "MATERIAL"
    dWorkspace = "Montgomery.gdb"
    domName = "Material"
    codedValue =  "ACP: Asbestos concrete"
    codeField = "TYPE"
    fieldDesc= "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, fieldDesc)
    # 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
