Question

嗨，我有一个这样的程序：

CREATE PROCEDURE dbo.DWS_PROG (
                                @fromDate datetime = '2012-01-01',
                                @maxMoney money = 200,
                                @limit int = 200 
                              )
AS
SET NOCOUNT ON; 

SELECT TOP (@limit)
     convert(int,P.P_ID) AS 'ID'
    , max(convert(MONEY,isnull(P.NGp,P.NGz))) AS 'NG'
    , max(convert(MONEY,(CASE WHEN D.Doc_Type = 0x0000000000000016 
                              THEN Cash_PLN 
                              ELSE 0 END))) AS 'Interests'
    , (SELECT TOP 1 convert(VARCHAR, H.Data_zmiany,105) 
         FROM dbo.Pozew_Historia_Stanow H 
        WHERE  H.P_ID = P.P_ID 
          AND H.Stan_nastepny_id = 0x000000000000000D /*PZ*/) AS 'Data Pozwu'
    , max((CASE WHEN Sad_Id=0x0000000000000E08 
                THEN 'EL' 
                ELSE 'PA' END)) AS 'TYPE'
    , max((CASE WHEN Cost_Name =0x0000000000000008 
                THEN convert(varchar, Pay_Date,105) 
                ELSE NULL END)) AS 'Data pierwszego kosztu wpisu sądowego'
    , (SELECT TOP 1 convert(VARCHAR, H.Data_zmiany,105) 
         FROM dbo.Pozew_Historia_Stanow H 
        WHERE H.P_ID = P.P_ID 
          AND H.Stan_nastepny_id = 0x00000000000000DD /*EGZ-1*/) AS 'Data wszczęcia egzekucji'
    , sum((CASE WHEN D.Doc_Type = 0x0000000000000003 
                 AND D.Pay_Date >= @fromDate 
                 AND D.Pay_Date < DATEADD(mm,DATEDIFF(mm,0,@fromDate) + 1,0) 
                THEN Cash_PLN 
                ELSE 0 END)) AS 'M0'
 FROM dbo.Pozew P 
 JOIN dbo.Orders  Z 
   ON Z.Orders_Id = P.Orders_Id 
 JOIN dbo.Docs D 
   ON D.P_ID = P.P_ID
WHERE ((P.NGp IS NOT NULL AND P.NGp < @maxMoney) OR (P.NGp IS NULL AND P.NGz < @maxMoney))
  AND P.Stan IN ('PZ-PORAŻKA','PZ-PORAŻ-UB','PZ-PSPPOR-SP','PZ-PSPPOR-UP','PZ-PSSSUK-UP','PZ-ZAPŁATA','EGZ-C-ROSZ-1','EGZ-C-ROSZ-2','EGZ-SUKCES-S','EGZ-ZAS-R','EGZ-NZAS-R','EGZ-BS-1C','EGZ-WSZP-1','EGZ-WSZP-2','EGZ-SPL')
  AND (SELECT TOP 1 dbo.Docs.Pay_Date 
         FROM dbo.Docs 
        WHERE dbo.Docs.P_ID = P.P_ID 
          AND dbo.Docs.Cost_Name = 0x0000000000000008 
     ORDER BY dbo.Docs.Pay_Date) >= @fromDate
GROUP BY P.P_ID

这基本上工作正常，但我有一个错误。在JOIN之前的最后一行，我为所有类型为0x00 ... 03的文档汇总现金，Pay_date为@param和月末之间的param。简单而有效：）

但我必须用子查询替换@fromDate：

SELECT TOP 1 dbo.Docs.Pay_Date 
  FROM dbo.Docs 
 WHERE dbo.Docs.P_ID = P.P_ID 
   AND dbo.Docs.Cost_Name = 0x0000000000000008 
   AND dbo.Docs.Pay_Date >= @fromDate  
 ORDER BY dbo.Docs.Pay_Date

因此，对于每个文档查询，将使用特定付款类型的第一个日期，然后它将汇总从该日期到月末的所有付款。

SUM应如下所示：

SUM((CASE WHEN D.Doc_Type = 0x0000000000000003 
           AND D.Pay_Date >= 
               (SELECT TOP 1 dbo.Docs.Pay_Date 
                  FROM dbo.Docs 
                 WHERE dbo.Docs.P_ID = P.P_ID 
                   AND dbo.Docs.Cost_Name = 0x0000000000000008 
                   AND dbo.Docs.Pay_Date >= @fromDate  
                 ORDER BY dbo.Docs.Pay_Date)

           AND D.Pay_Date < DATEADD(mm, DATEDIFF(mm, 0, 
              (SELECT TOP 1 dbo.Docs.Pay_Date 
                 FROM dbo.Docs 
                WHERE dbo.Docs.P_ID = P.P_ID 
                  AND dbo.Docs.Cost_Name = 0x0000000000000008 
                  AND dbo.Docs.Pay_Date >= @fromDate 
                ORDER BY dbo.Docs.Pay_Date)) + 1,0) 
         THEN Cash_PLN 
         ELSE 0 END)) AS 'M0'

但在执行该操作后，Management Studio会抛出错误：

无法对包含聚合或子查询的表达式执行聚合函数。

我试图解决这个问题将近2天。有什么想法吗？

很抱歉没有显示表的结构，但数据库太大了，我只需要一种方法来解决这个错误：）

我的表看起来像这样：表Pozew：id，name等

表格文档：docid，p_id（来自Pozew表的密钥），doc_type，cost_name，pay_date，cash_PLN

示例记录如下：

文档：

1,1,15,8， '2011-02-04'，400个
1,1,3,5，'2011-02-09'，0
1,1,3,5，'2011-02-12'，0
1,1,3,5，'2011-02-04'，0

简单场景：我们在docs表中添加一条记录，说我们有第1个文件，其中cost_name = 0x8，然后添加了其他文件但Doc_Type = 0x3。

因此，我们希望获取所有doc_Type = 0x3的文档，并在第一个文档的创建日期与cost_name = 0x8和月末之间添加。但是我们必须为每个Pozew_id分组它们。

抱歉我的英语：/

我创建了一个简单的查询，可以更清楚地显示我的问题：

DECLARE @fromDate varchar
SET @fromDate = '2011-06-01'
SELECT TOP 100
sum((CASE WHEN D.Typ_dokumentu = 0x0000000000000003 
          AND D.Data_platnosci >= 
          (SELECT TOP 1 Data_platnosci
           FROM Dokumenty
           WHERE Pozew_Id = P.Pozew_Id 
           AND Nazwa_kosztu = 0x0000000000000008
           AND Data_platnosci >= @fromDate 
           GROUP BY Pozew_Id) 
          AND Data_platnosci < DATEADD(mm,DATEDIFF(mm,0,
          (SELECT TOP 1 Data_platnosci 
           FROM Dokumenty 
           WHERE Pozew_Id = P.Pozew_Id
           AND Nazwa_kosztu = 0x0000000000000008
           AND Data_platnosci >= @fromDate
           GROUP BY Pozew_Id)
           ) + 1,0) THEN Kwota_PLN ELSE 0 END)) AS 'M0'
FROM
Dokumenty D
JOIN Pozew P
    ON D.Pozew_Id = P.Pozew_Id
WHERE
((P.NGp IS NOT NULL
AND
P.NGp < 200)
OR
(P.NGp IS NULL
AND
P.NGz < 200))
AND
P.Stan IN ('PZ-PORAŻKA','PZ-PORAŻ-UB','PZ-PSPPOR-SP')
AND
(SELECT TOP 1
     dbo.Dokumenty.Data_platnosci
 FROM
     dbo.Dokumenty
 WHERE
     dbo.Dokumenty.Pozew_Id = P.Pozew_Id
     AND
     dbo.Dokumenty.Nazwa_kosztu = 0x0000000000000008
 ORDER BY
     dbo.Dokumenty.Data_platnosci) >= @fromDate

Answer 1

我会将pay_date放入变量并使用它。毕竟它是一个恒定的值。

DECLARE @pay_date datetime
SET @pay_date = (SELECT TOP 1 dbo.Docs.Pay_Date 
                   FROM dbo.Docs 
                  WHERE dbo.Docs.P_ID = P.P_ID 
                    AND dbo.Docs.Cost_Name = 0x0000000000000008 
                    AND dbo.Docs.Pay_Date >= @fromDate  
                  ORDER BY dbo.Docs.Pay_Date)

然后在你的查询中

  AND D.Pay_Date >= @pay_date

Answer 2

是否有可能在您的联接中有一个派生表来提供“每种付款类型的@fromDate之后的第一个”，然后在您的select语句中进行比较。

即派生的查询类似

select p_id, min(pay_date) startDate  
from docs 
where cost_name = 0x0000000000000008 
  and pay_date >= @fromDate 
group by p_id 
order by pay_date

您可以按付款类型加入派生表，从而获得适当的开始日期。

然后你的总和是：

sum((case when d.doc_type = 0x0000000000000003 
           and d.pay_date >= startDate 
           and month(d.pay_date) = month(startDate) 
           and year(d.pay_date) = year(startDate)) then cash_pln 
          else 0 end) as 'M0'

注意我没有试过这个，所以它可能不完全正确，但希望它显示原则
