日付範囲のレコードのギャップを特定します

Question

質問：私は1日に2つのレコードを持たないレコードを特定したいと思います。それぞれの日のための第二の記録....

SELECT TR.tourid, 
     TR.tourruntimestamp, 
     TC.tourname, 
     TC.tourfrequency, 
     TC.unit, 
     TC.division, 
     RANK() 
     OVER (
      PARTITION BY TR.tourid 
      ORDER BY TR.tourruntimestamp) AS [Rank] 
FROM DBO.tbltourrun AS TR 
     INNER JOIN DBO.tso_piml_tour_config AS TC 
       ON TC.tourid = TR.tourid 
WHERE (TC.tourfrequency = '2xDay') 
     AND (TR.tourruntimestamp BETWEEN Dateadd(DAY, Datediff(DAY, 0, Getdate()) - 1, 0) AND Dateadd(DAY, Datediff(DAY, 0, Getdate()), 0)) 

Answer 1

もっと一般的な答えがあるかどうランクは私に語りました。私は以下に正しい方向にあなたを取得する必要が不自然な例であるあなたは数週間、数ヶ月など

select  * 

from  (SELECT  TR.TourID, TR.TourRunTimeStamp, TC.tourName, TC.tourFrequency, TC.Unit, TC.Division 
         ,count(*) OVER (PARTITION BY TR.TourID) AS cnt 
      FROM   dbo.tblTourRun AS TR INNER JOIN 
            dbo.TSO_PIML_Tour_Config AS TC ON TC.tourID = TR.TourID 
      WHERE   TR.TourRunTimeStamp BETWEEN DATEADD(day, DATEDIFF(day, 0, GETDATE()) - 1, 0) AND DATEADD(day, DATEDIFF(day, 0, GETDATE()), 0)) 
      ) t 

where  cnt <> case TC.tourFrequency when '1xDay' then 1 when '2xDay' then 2 when '4xDay' then 4 end 
;

select  * 

from  (SELECT  TR.TourID, TR.TourRunTimeStamp, TC.tourName, TC.tourFrequency, TC.Unit, TC.Division, count(*) OVER (PARTITION BY TR.TourID) AS cnt 
      FROM   dbo.tblTourRun AS TR INNER JOIN 
            dbo.TSO_PIML_Tour_Config AS TC ON TC.tourID = TR.TourID 
      WHERE  (TC.tourFrequency = '2xDay') AND (TR.TourRunTimeStamp BETWEEN DATEADD(day, DATEDIFF(day, 0, GETDATE()) - 1, 0) AND DATEADD(day, DATEDIFF(day, 0, GETDATE()), 0)) 
      ) t 

where  cnt = 1 
; 

Answer 2

でやりたいんかわかりません。私はあなたが作業しようとしているデータの形状をシミュレートするために作られた値のテーブルを使用しています（この例には関係のない値を取り除きます）。

select a.TourId 
    , b.TourDate 
from (values 
    (1, Convert(datetime2(0), N'2016-01-01 00:00:00')) 
    , (1, Convert(datetime2(0), N'2016-01-01 04:00:00')) 
    , (1, Convert(datetime2(0), N'2016-01-03 00:00:00')) 
    , (1, Convert(datetime2(0), N'2016-01-04 00:00:00')) 
    , (1, Convert(datetime2(0), N'2016-01-04 04:00:00')) 
    , (1, Convert(datetime2(0), N'2016-01-05 00:00:00')) 
    , (2, Convert(datetime2(0), N'2016-02-11 00:00:00')) 
    , (2, Convert(datetime2(0), N'2016-02-11 18:00:00')) 
    , (2, Convert(datetime2(0), N'2016-02-13 00:00:00')) 
    , (2, Convert(datetime2(0), N'2016-02-14 00:00:00')) 
    , (2, Convert(datetime2(0), N'2016-02-14 18:00:00')) 
    , (2, Convert(datetime2(0), N'2016-02-15 00:00:00')) 
) as a (TourId, TourRunTimeStamp) 
cross apply (values(Convert(date, a.TourRunTimeStamp))) as b (TourDate) 
group by a.TourId 
     , b.TourDate 
having Count(1) != 2; -- find ids with exactly two entries 
-- having Count(1) in (2, 4); -- find ids with exactly two or four entries 
-- having Count(1) % 2 = 0; -- find ids with an even number of entries 

ここにロジック単純です：日付に日時を変換する（我々は計算再利用できるように、この限りで句で行われている）、TourId + TourDateのグループは、レコードの数を数えます2に等しいカウントを持たないすべての結果を除外します。

Answer 3

最終SQL結果：
一部CTEのか、見解の助けを借りて、私はそれを動作させることができました。ツアーそう不在されたとき

1. クエリ1-ツアー日付の範囲（昨日）
2. クエリ日付スタンプ列に
3. クエリ3-条件カウントをゼロとして無日付スタンプ付きツアーを示す2-概要間走っ私は逃したルート
