Question

我正在尝试在我的Python脚本中使用SQL表达式中的范围列表，但每当我尝试运行它时，它都会给我以下错误。

ExecuteError: ERROR 999999: Error executing function.
An invalid SQL statement was used.
An invalid SQL statement was used. [PatientVisitsGeocoded]
An invalid SQL statement was used. [SELECT ObjectID FROM PatientVisitsGeocoded WHERE USER_CenterID = 1001 AND USER_MonthsSinceFHOpening = (1, 3)]
Failed to execute (FeatureClassToFeatureClass)

但是，当我只使用一个范围而不是范围列表时，脚本运行正常。

我很难找到包含范围的列表示例，我从本页的最佳答案开发了我的列表语法：

Python List with ranges

我不知道我的范围列表的语法是错误的还是我需要改变表达式的构造方式。任何建议/帮助将不胜感激。

这是我的完整代码：

# Set environment settings
arcpy.env.workspace = r"C:\arcGIS_Shared\Python\CenterHeatMaps6.gdb"

#Declare variables
fc = 'Open_GoHealth_Centers'
fields = ['USER_market_id','USER_GoHealth_ID','USER_GoHealth_Center_Name','USER_Opening_Date', 'USER_MonthsSinceFHOpening']
fieldname = 'USER_market_id'

# Set Markets to loop through
markets = [1000]
# Set Years to loop through
years = [2014, 2015]
# Set Ranges to loop through
myranges = [(1,3),(1,4),(1,5)]

sqlclause = (None, 'Order By USER_market_id, USER_GoHealth_ID')

for market in markets:
    print (market)
    #Define WHERE clause statement
    whereclause = """{} = """.format(arcpy.AddFieldDelimiters(fc, fieldname)) + str(market)

    for year in years:
        print (year)
        for myrange in myranges:
            print (myrange)
            with arcpy.da.SearchCursor(in_table = fc, field_names = fields, where_clause=whereclause, sql_clause=(None, 'ORDER BY USER_market_id, USER_GoHealth_ID')) as cursor:
                #Loop through each row established in cursor
                for row in (cursor):
                    # Set local variables for the FeatureClasstoFeatureClass tool
                    inFeatures = "PatientVisitsGeocoded"
                    outLocation = r"C:\arcGIS_Shared\Python\CenterHeatMaps6.gdb"
                    outFeatureClass = "PatientVisits{0}_{1}_{3}".format(row[0], row[2], myrange, year) 
                    delimitedfield = arcpy.AddFieldDelimiters(arcpy.env.workspace,"USER_CenterID")
                    expression = """{0} = {1} AND USER_MonthsSinceFHOpening = {2}""".format(delimitedfield, row[1], myrange) 
                    print (expression)

#                   Execute FeatureClassToFeatureClass tool
                    arcpy.FeatureClassToFeatureClass_conversion(inFeatures, outLocation, outFeatureClass, expression)

#                   #Print Results
                    print(row[2])
                    print(year)
                    print(myrange)

Answer 1

应该是In (1, 3)而不是= (1, 3)。

如果您想要值1和3之间的范围，请使用Between 1 and 3。 In表示“匹配其中一个值”，但不具有包容性。

SQL表达式中使用的范围列表，创建“无效的SQL语句”错误
