Question

我正在检查一个月的初始和最终余额，我已经提出了查询以获取其中任何一个，但我需要在同一个查询中显示这两个结果。我无法进行子查询，因为我在查询中使用GROUP BY，据我所知，在进行子查询时我无法使用它。我很感激有经验的SQL用户提供的任何指针或建议。

DECLARE @Year INT SET @Year = 2016
DECLARE @Month varchar(4) SET @Month = '07'

SELECT T2.[Segment_0]+'-'+T2.[Segment_1]+'-'+T2.[Segment_2] Account,
T2.[AcctName], 
SUM(T0.[Debit])-SUM(T0.[Credit]) Balance
FROM  JDT1 T0  
INNER  JOIN OJDT T1  
ON  T1.[TransId] = T0.[TransId] 
INNER JOIN oact T2
ON T2.[AcctCode] = T0.[Account]
where t0.RefDate >= @From and convert(varchar(7), T0.RefDate ,111) < LTRIM(str(@Year)) + '/' + @Month --Initial
--where t0.RefDate >= @From and convert(varchar(7), T0.RefDate ,111) <= LTRIM(str(@Year)) + '/' + @Month --Final
GROUP BY T2.[Segment_0]+'-'+T2.[Segment_1]+'-'+T2.[Segment_2],T2.[AcctName]
order by T2.[Segment_0]+'-'+T2.[Segment_1]+'-'+T2.[Segment_2]

正如您所看到的那样只有LESS THAN和LESS OR EQUAL THAN问题，但我在查询中需要两个结果。我缺乏经验让我对此感到震惊。

Answer 1

也许这会有用..我相信如果我们对数据结构有更好的了解，我们可以提出一些可行的子查询

DECLARE @Year INT
SET @Year = 2016
DECLARE @Month VARCHAR(4)
SET @Month = '07'

SELECT  T2.[Segment_0] + '-' + T2.[Segment_1] + '-' + T2.[Segment_2] Account,
        T2.[AcctName],
        SUM(CASE WHEN CONVERT(VARCHAR(7),T0.RefDate,111) < LTRIM(STR(@Year)) + '/' + @Month THEN T0.[Debit] END) - 
            SUM(CASE WHEN CONVERT(VARCHAR(7),T0.RefDate,111) < LTRIM(STR(@Year)) + '/' + @Month THEN T0.[Credit] END) AS Intitial,
        SUM(CASE WHEN convert(varchar(7), T0.RefDate ,111) <= LTRIM(str(@Year)) + '/' + @Month THEN T0.[Debit] END) - 
            SUM(CASE WHEN convert(varchar(7), T0.RefDate ,111) <= LTRIM(str(@Year)) + '/' + @Month THEN T0.[Credit] END) AS Final
FROM    JDT1 T0
        INNER  JOIN OJDT T1 ON T1.[TransId] = T0.[TransId]
        INNER JOIN oact T2 ON T2.[AcctCode] = T0.[Account]
WHERE   t0.RefDate >= @From
GROUP BY T2.[Segment_0] + '-' + T2.[Segment_1] + '-' + T2.[Segment_2],
        T2.[AcctName]
ORDER BY T2.[Segment_0] + '-' + T2.[Segment_1] + '-' + T2.[Segment_2]

如果使用CTE清理一些，可能会更有意义

DECLARE @Year INT
SET @Year = 2016
DECLARE @Month VARCHAR(4)
SET @Month = '07'
DECLARE @YearMonth VARCHAR(7) = LTRIM(STR(@Year)) + '/' + @Month

;WITH cte AS
(
    SELECT  T2.[Segment_0] + '-' + T2.[Segment_1] + '-' + T2.[Segment_2] [Account],
            T2.[AcctName],
            CONVERT(VARCHAR(7),T0.RefDate,111) [RefDate],
            T0.[Debit],
            T0.[Credit]
    FROM    JDT1 T0
            INNER  JOIN OJDT T1 ON T1.[TransId] = T0.[TransId]
            INNER JOIN oact T2 ON T2.[AcctCode] = T0.[Account]
    WHERE   t0.RefDate >= @From
)
SELECT  Account,
        AcctName,
        SUM(CASE WHEN RefDate < @YearMonth THEN [Debit] END) - SUM(CASE WHEN RefDate < @YearMonth THEN [Credit] END) AS Initial,
        SUM(CASE WHEN RefDate <= @YearMonth THEN [Debit] END) - SUM(CASE WHEN RefDate <= @YearMonth THEN [Credit] END) AS Final,
FROM    cte
GROUP BY Account,
        AcctName
ORDER BY Account

Answer 2

如果您需要两者，请使用<=。 <=将获得<所有的行，加上一些......所以使用<是多余的。除了这个操作数，你的where子句是相同的。

修改

试试这个......

SELECT T2.[Segment_0]+'-'+T2.[Segment_1]+'-'+T2.[Segment_2] Cuenta, T2.[AcctName], ISNULL((select SUM([Debit]) - SUM([Credit]) from JDT1 where TransId = T0.TransID and RefDate >= @From and convert(varchar(7), RefDate ,111) < LTRIM(str(@Year)) + '/' + @Month),0) as [Initial Saldo Final], ISNULL((select SUM([Debit]) - SUM([Credit]) from JDT1 where TransId = T0.TransID and RefDate >= @From and convert(varchar(7), RefDate ,111) <= LTRIM(str(@Year)) + '/' + @Month),0) as [Final Saldo Final] FROM JDT1 T0 INNER JOIN OJDT T1 ON T1.[TransId] = T0.[TransId] INNER JOIN oact T2 ON T2.[AcctCode] = T0.[Account] order by T2.[Segment_0]+'-'+T2.[Segment_1]+'-'+T2.[Segment_2]

需要来自同一查询的两个不同结果
