设置值域范围 (数据管理)
摘要
设置现有值域范围的最小值和最大值。
用法
语法
SetValueForRangeDomain_management (in_workspace, domain_name, min_value, max_value)
参数 | 说明 | 数据类型 |
in_workspace |
包含要更新的属性域的地理数据库。 | Workspace |
domain_name |
要更新的值域范围的名称。 | String |
min_value |
值域范围的最小值。 | String |
max_value |
值域范围的最大值。 | String |
代码实例
设置值域范围示例(Python 窗口)
以下 Python 窗口脚本演示了如何在即时模式下使用 SetValueForRangeDomain 函数。
import arcpy
from arcpy import env
env.workspace = "C:/data"
arcpy.SetValueForRangeDomain_management("montgomery.gdb", "RotAngle", 0, 359)
设置值域范围示例 2(独立脚本)
此独立脚本在创建属性范围域的工作流中使用 SetValueForRangeDomain 函数。
# Name: CreateRangeDomain.py
# Purpose: Create an attribute domain to constrain valid rotation angle
# Author: ESRI
# Import system modules
import arcpy
from arcpy import env
try:
# Set the workspace (to avoid having to type in the full path to the data every time)
env.workspace = "C:/data"
# Set local parameters
dWorkspace = "montgomery.gdb"
domName = "RotAngle2"
domDesc = "Valid rotation angle"
minRange = 0
maxRange = 359
inFeatures = "Montgomery.gdb/Water/fittings"
inField = "ANGLE"
# Process: Create the range domain
arcpy.CreateDomain_management(dWorkspace, domName, domDesc, "LONG", "RANGE")
# Process: Set the minimum and maximum values for the range domain
arcpy.SetValueForRangeDomain_management(dWorkspace, domname, minRange, maxRange)
# Process: Constrain the fitting rotation angle
arcpy.AssignDomainToField_management( inFeatures, inField, domName)
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
