删除属性域 (数据管理)
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，则其无法删除。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立即模式下使用 DeleteDomain 函数。
import arcpy from arcpy import env 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 # 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
