Question

こんにちは私はSSRS でレポートのデータセットに取り組んでいると私は、バックログの総要求与えクエリがあります。

SELECT 
COUNT(*) as NB 
FROM p_rqt WITH (NOLOCK) 
INNER JOIN p_cpy WITH (NOLOCK) ON p_cpy.CpyInCde = p_rqt.OrigCpyInCde 
WHERE 
    CpyTypInCde IN (27, 31) 
    AND p_rqt.RqtNatInCde IN (74, 75, 76) 
    AND HeadRqtInCde = 0 
    AND p_rqt.OrigCpyInCde LIKE CASE WHEN @Client = 0 THEN '%' ELSE @Client END 
    AND ((RcvDte < DATEADD(day, 1, @DateDeb) AND RqtEndDte IS NULL) OR 
(RcvDte < DATEADD(day, 1, @DateDeb) AND RqtEndDte > DATEADD(day, 1, @DateDeb))) 

をし、私が取得したいです1日に残された合計金額。 私はこのような多くのことを試してみました：

SELECT CONVERT(date,rcvdte,103), count(*) as nb 
FROM p_rqt p WITH (NOLOCK) 
INNER JOIN p_cpy WITH (NOLOCK) ON p_cpy.CpyInCde = p.OrigCpyInCde 
WHERE 
    CpyTypInCde IN (27, 31) 
    AND p.RqtNatInCde IN (74, 75, 76) 
    AND HeadRqtInCde = 0 
    AND ((RcvDte < DATEADD(day, 1, '20170901') AND RqtEndDte IS NULL) OR (RcvDte < DATEADD(day, 1, '20170901') AND RqtEndDte > DATEADD(day, 1, '20170901'))) 
    group by CONVERT(date,rcvdte,103) 
    order by CONVERT(date,rcvdte,103) 

私は、内側のサブクエリ、合計や他のもの に参加するが、私はやって管理することができ、すべてが一日 あたりに追加されたレコードの数を持つことであると私はのような何かをしたいしようとしましたこの：

date:    NB: 
01/01/2017  1950 
02/01/2017  1954    (+4 items) 
03/01/2017  1945    (-9 items)

だから私はまだ答えを投稿私は解決策を見つけたが、それは本当に遅いです、 とにかく

  DECLARE @Tb TABLE ( Colonne1 Datetime, Colonne2 INT) 
DECLARE @Debut Datetime = '01/09/2017' 
WHILE @Debut < '13/09/2017' 
BEGIN 
    DECLARE @Compteur int = (
     SELECT 
       COUNT(1) NB 
       FROM p_rqt WITH (NOLOCK) 
       INNER JOIN p_cpy WITH (NOLOCK) ON p_cpy.CpyInCde = p_rqt.OrigCpyInCde 
       WHERE 
         CpyTypInCde IN (27, 31) 
         AND p_rqt.RqtNatInCde IN (74, 75, 76) 
         AND HeadRqtInCde = 0 
         AND p_rqt.OrigCpyInCde LIKE '%' 
         AND (
           (RcvDte < @Debut AND RqtEndDte IS NULL) 
           OR 
           (RcvDte < @Debut AND RqtEndDte > @Debut) 
         ) 
    ) 
    INSERT INTO @Tb (Colonne1, Colonne2) VALUES (@Debut, @Compteur) 
    SET @Debut = DATEADD(day, 1, @Debut) 
    IF @Debut > '13/09/2017' 
    BREAK 
    ELSE 
    CONTINUE 
    END 
    SELECT * FROM @Tb

使用LAGありがとう：

WITH cte AS (
    SELECT 
     CONVERT(date, rcvdte, 103) AS date, 
     COUNT(*) AS nb 
    FROM p_rqt p WITH (NOLOCK)
