摘要
从编码值属性域中移除值。
用法
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。
只能在模型构建器中使用编码值参数的添加值按钮。在模型构建器中,如果先前的工具尚未运行或其派生数据不存在,则可能不会对编码值参数填充值。 添加值按钮允许您添加所需值,以便继续构建模型。
语法
DeleteCodedValueFromDomain_management (in_workspace, domain_name, code)
参数 | 说明 | 数据类型 |
in_workspace | 包含要更新的属性域的工作空间。 | Workspace |
domain_name | 要更新的编码值属性域的名称。 | String |
code [code,...] | 要从指定的属性域中删除的值。 | String |
代码示例
从属性域中删除编码值的示例(Python 窗口)
以下 Python 窗口脚本演示了如何在即时模式下使用 CreateDomain 函数。
import arcpy
arcpy.env.workspace = "C:/data"
arcpy.DeleteCodedValueFromDomain_management("montgomery.gdb", "DistDiam", ["20","24"])
从属性域中删除编码值的示例 2(独立脚本)
该独立脚本将 DeleteCodedValueFromDomain 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 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 as err:
print(err.args[0])
