Domain To Table (Data Management)
Summary
Creates a table from an attribute domain.
Usage
-
Creating a table from an attribute domain allows for additional editing of the table in ArcMap. 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.
-
Workspace domains can also be managed in ArcCatalog or the Catalog window. Domains can be created and modified through the Domains tab on the Database Properties dialog box.
Syntax
Parameter | Explanation | Data Type |
in_workspace |
The workspace containing the attribute domain to be converted to a table. | Workspace |
domain_name |
The name of the existing attribute domain. | String |
out_table |
The table to be created. | Table |
code_field |
The name of the field in the created table that will store code values. | String |
description_field |
The name of the field in the created table that will store code value descriptions. | String |
configuration_keyword (Optional) |
For SDE tables, the custom storage keywords for creating the table. | String |
Code Sample
The following Python window script demonstrates how to use the DomainToTable function.
import arcpy
from arcpy import env
env.workspace = "C:/data"
arcpy.DomainToTable_management("montgomery.gdb", "DistDiam", "diameters", "code", "descript")
This stand-alone script uses the DomainToTable function as part of a workflow to edit a domain.
# Name: RemoveDomainsExample.py
# Purpose: Update an attribute domain to constrain valid pipe material values
# Author: ESRI
# Import system modules
import arcpy, os
from arcpy import env
try:
# Set the workspace (to avoid having to type in the full path to the data every time)
env.workspace = "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
except Exception, e:
# If an error occurred, print line number and error message
import traceback, sys
tb = sys.exc_info()[2]
print "Line %i" % tb.tb_lineno
print e.message
