描述
从工作空间删除属性域。
使用方法
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。
还可以在属性域视图中管理属性域,可通过单击数据功能区中设计组内的属性域按钮将其打开。
语法
DeleteDomain(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 |
派生输出
名称 | 说明 | 数据类型 |
out_workspace | 已更新的输入工作空间 | 工作空间 |
代码示例
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")
此独立脚本将 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
# 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,
os.path.join(dWorkspace, 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
