Delete Coded Value From Domain (Data Management)
Summary
Removes a value from a coded value domain.
Usage
-
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.
-
The Code Value parameter Add Value button is used only in ModelBuilder. In ModelBuilder, where the preceding tool has not been run, or its derived data does not exist, the Code Value parameter may not be populated with values. The Add Value button allows you to add expected values so you continue to build your model.
Syntax
Parameter | Explanation | Data Type |
in_workspace |
The workspace containing the domain to be updated. | Workspace |
domain_name |
The name of the coded value domain to be updated. | String |
code [code,...] |
The value(s) to be deleted from the specified domain. | String |
Code Sample
The following Python window script demonstrates how to use the CreateDomain function in immediate mode.
import arcpy
from arcpy import env
env.workspace = "C:/data"
arcpy.DeleteCodedValueFromDomain_management("montgomery.gdb", "DistDiam", ["20","24"])
This stand-alone script uses the DeleteCodedValueFromDomain 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"
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, 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
