删除属性域

摘要

从工作空间删除属性域。

用法

  • 如果属性域与要素类或表相关联，则无法将其删除。使用移除字段的属性域工具可移除要素类（或表）与属性域之间的关联。

  • 还可以在 ArcCatalog 或目录窗口中管理工作空间属性域。可通过数据库属性对话框中的属性域选项卡创建和修改属性域。

语法

DeleteDomain_management (in_workspace, domain_name)
参数说明数据类型
in_workspace

包含要删除的属性域的地理数据库。

Workspace
domain_name

要删除的属性域的名称。

String

代码示例

删除属性域示例（Python 窗口）

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

import arcpy
arcpy.env.workspace = "C:/data"
arcpy.DeleteDomain_management("montgomery.gdb", "DistDiam")
删除属性域示例 2（独立脚本）

该独立脚本将 DeleteDomain 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
# Import system modules
import arcpy
import 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 standard 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])
