参数说明数据类型
in_table

包含要移除的属性域的输入表。

Table View

代码示例

移除字段的属性域示例(Python 窗口)

以下 Python 窗口脚本演示了如何在即时模式下使用 RemoveDomainFromField 函数。

import arcpy
from arcpy import env 
env.workspace = "C:/data"
arcpy.RemoveDomainFromField_management("montgomery.gdb/water/distribmains", "DIAMETER")
移除字段的属性域示例 2(独立脚本)

此独立脚本将 RemoveDomainFromField 函数用作编辑属性域的工作流的一部分。

# 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
