GET差值結果

Question

開始 之前我有查看 'PageViewModSession' 它的代碼是

SELECT  CONVERT(datetime, CONVERT(varchar(14), VisitStartDateTime) + ':00:00') AS DateValue, MAX(dbo.PageLogGroupByDateTimeFull(VisitStartDateTime)) AS PageLogCount, 
        (CASE MAX(dbo.SessionGroupByDateTimeFull(VisitStartDateTime)) WHEN 0 THEN 1 ELSE MAX(dbo.SessionGroupByDateTimeFull(VisitStartDateTime)) END) AS SessionLogCount, SiteInfoID 
FROM   dbo.PageLog 
GROUP BY CONVERT(varchar(14), VisitStartDateTime), SiteInfoID 

和時選擇此查看我的結果是

當使用此合成文本進行選擇

var obj = db.PageViewModSessions.AsQueryable(); 

結果是

的結果

我抓住創建的SQL查詢的查詢分析器中

SELECT 
[Extent1].[DateValue] AS [DateValue], 
[Extent1].[PageLogCount] AS [PageLogCount], 
[Extent1].[SessionLogCount] AS [SessionLogCount], 
[Extent1].[SiteInfoID] AS [SiteInfoID] 
FROM (SELECT 
[PageViewModSession].[DateValue] AS [DateValue], 
[PageViewModSession].[PageLogCount] AS [PageLogCount], 
[PageViewModSession].[SessionLogCount] AS [SessionLogCount], 
[PageViewModSession].[SiteInfoID] AS [SiteInfoID] 
FROM [dbo].[PageViewModSession] AS [PageViewModSession]) AS [Extent1] 

和結果

每一行中重複行的一個是
