Question

当我在查询下方运行时，它会给我错误Invalid column name '2017-09'.，我尝试了一些谷歌搜索，但仍然没有得到它的结果，任何人都可以请看看这个查询，并帮助我可能是什么问题

在SQL-Server中，您必须在使用Single Quotes(')时使用Double Quotes(")而不是Strings。

试试这个：

SELECT 
COUNT(CASE when (SOC = '1' and MonthStart='2017-09') then 1 ELSE NULL END) as SOCCount_2017_09, 
COUNT(CASE when (Recert = '1' and MonthStart='2017-09') then 1 ELSE NULL END) as RecertCount_2017_09, 
COUNT(CASE when (Recert = '1' and MonthStart='2017-09') then 1 ELSE NULL END) as RecertPer1_2017_09, 
COUNT(CASE when (MonthStart='2017-09') then 1 ELSE NULL END) as TotalEpisode_2017_09, 
ROUND(AVG(CASE when (FullHHRG > '0' and MonthStart='2017-09') then FullHHRG ELSE NULL END),2) as AvgFullHHRG_2017_09,
ROUND(AVG(CASE when (CMW > '0' and MonthStart='2017-09') then CMW ELSE NULL END),3) as AvgCMW_2017_09, 
COUNT(CASE when (LUPA = '1' and MonthEnd='2017-09') then 1 ELSE NULL END) as LUPAs_2017_09, 
COUNT(CASE when (LUPA = '1' and MonthEnd='2017-09') then 1 ELSE NULL END) as LUPAPer_2017_09, 
COUNT(CASE when ((MonthEnd='2017-09' and Status = 'Closed') ) then 1 ELSE NULL END) as TotalEndEpisode_2017_09, 
ROUND(AVG(CASE when (SN_Ep = '1' and MonthEnd='2017-09') then SN_Visits ELSE NULL END),1) as SNVisitsSNEps_2017_09, 
ROUND(AVG(CASE when (THVisits > '0' and MonthEnd='2017-09') then THVisits ELSE NULL END),1) as THVisitsTHEps_2017_09, 
ROUND(AVG(CASE when (Status = 'Closed' and MonthEnd='2017-09') then TotVisits ELSE NULL END),1) as AvgTotVisits_2017_09, 
ROUND(AVG(CASE when (Status = 'Closed' and MonthEnd='2017-09') then SNVisits ELSE NULL END),1) as AvgSNVisits_2017_09, 
ROUND(AVG(CASE when (Status = 'Closed' and MonthEnd='2017-09') then TotTherapy ELSE NULL END),1) as AvgTHVisits_2017_09, 
ROUND(AVG(CASE when (NetHHRG > '0' and MonthEnd='2017-09') then NetHHRG ELSE NULL END),2) as AvgNetHHRG_2017_09, 
SUM(CASE when (Status = 'Closed' and MonthEnd='2017-09') then TH_Ep ELSE NULL END) as TherapyPer_2017_09 
FROM tb_Episode WHERE CustID = '27' AND PayerType = 'Ep' AND BranchID IN (241)

运行sql查询时出现“无效列名'2017-09'..”的错误
