SQL Server 2014 Sélectionnez total pour chaque jour

Question

Bonjour Je travaille sur un ensemble de données pour un rapport SSRS et j'ai une question qui donne le nombre total de demandes de l'arriéré:

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))) 

et je veux récupérer le montant total restant par jour. J'ai essayé beaucoup de choses comme ceci:

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) 

J'ai essayé jointure sous-requêtes, Somme et d'autres choses mais tout ce que je peux réussir à faire est d'avoir le nombre d'enregistrements ajoutés par jour et je veux quelque chose comme ceci:

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

Merci

Answer 1

donc j'ai trouvé une solution, mais il est vraiment lent, je poste encore l'échantillon réponse de toute façon

  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

utilisation LAG:

WITH cte AS (
    SELECT 
     CONVERT(date, rcvdte, 103) AS date, 
     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) 
) 

SELECT 
    t1.date, 
    (SELECT SUM(t2.nb) FROM cte t2 WHERE t2.date <= t1.date) AS nb, 
    CASE WHEN t1.nb - LAG(t1.nb, 1, t1.nb) OVER (ORDER BY t1.date) > 0 
     THEN '(+' + (t1.nb - LAG(t1.nb, 1, t1.nb) OVER (ORDER BY t1.date)) + ' items)' 
     ELSE '(' + (t1.nb - LAG(t1.nb, 1, t1.nb) OVER (ORDER BY t1.date)) + ' items)' 
    END AS difference 
FROM cte t1 
ORDER BY t1.date;
