Question

希望我在这里有一个简单的问题，并以正确的方式向您解释。

我有以下查询：

--DECLARE DATES
DECLARE @Date datetime
DECLARE @DaysInMonth INT
DECLARE @i INT

--GIVE VALUES
SET @Date = Getdate()
SELECT @DaysInMonth = datepart(dd,dateadd(dd,-1,dateadd(mm,1,cast(cast(year(@Date) as varchar)+'-'+cast(month(@Date) as varchar)+'-01' as datetime))))
SET @i = 1

--MAKE TEMP TABLE
CREATE TABLE #TempDays
(
    [days] VARCHAR(50)
)

WHILE @i <= @DaysInMonth
BEGIN
    INSERT INTO #TempDays
    VALUES(@i)
    SET @i = @i + 1
END



    SELECT #TempDays.days, DATEPART(dd, a.ActualDate) ActualDate, a.ActualAmount, (SELECT SUM(b.ActualAmount)
                           FROM UnpaidManagement..Actual b
                           WHERE b.ID <= a.ID) RunningTotal
    FROM   UnpaidManagement..Actual a
    RIGHT JOIN #TempDays on a.ID = #TempDays.days



DROP TABLE #TempDays

产生以下输出：

如果仔细查看上表，“ActualDate”列缺少一些值，EG：9,16等。

正因为如此，行被推高而不是按正确的数字分组？我如何通过/任何方式完成一组以使它们保持正确的行？

期望的输出：

+------+------------+--------------+--------------+

我知道这是一个很长的阅读，但如果我已经清楚地解释了这一点，请告诉我。我整个上午一直试图分组，但我一直都有错误。

Answer 1

SELECT #TempDays.days, DATEPART(dd, a.ActualDate) ActualDate, a.ActualAmount, (SELECT SUM(b.ActualAmount)
                       FROM UnpaidManagement..Actual b
                       WHERE b.ID <= a.ID) RunningTotal
FROM   UnpaidManagement..Actual a
RIGHT JOIN #TempDays on  DATEPART(dd, a.ActualDate) = #TempDays.days

Answer 2

如果您选择临时表作为选择中的第一个表并加入UnpaidManagement..Actual，那么您的日期将按正确的行和顺序排列：

SELECT t.days
    ,DATEPART(dd, a.ActualDate) ActualDate
    ,a.ActualAmount
    ,(
        SELECT SUM(b.ActualAmount)
        FROM UnpaidManagement..Actual b
        WHERE b.ID <= a.ID
    ) RunningTotal
FROM #TempDays AS t
INNER JOIN UnpaidManagement..Actual AS a ON a.IDENTITYCOL = t.days
ORDER BY t.days

完成此操作后，cou可以添加CASE WHEN以生成NULL单元格的内容。

分组/订购混淆
