SQL Server查询每06:30对值进行计数

标签： c# sql-server sql-server-2008-r2

请帮助我。我的数据和查询有问题。 请先看看我的餐桌设计。

 CREATE TABLE [dbo].[my_table](
    [ID] [int] NOT NULL,
    [date] [datetime] NULL,
    [value] [int] NULL,
    [product_code] [varchar](50) NULL,
    [expectedvalue] [int] NULL,
 CONSTRAINT [PK_my_table] PRIMARY KEY CLUSTERED 
(
    [ID] ASC
)WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
) ON [PRIMARY]
GO

这是数据，每分钟从机器中获取所有数据。

数据方案1（06:30的值不为0）：

我想从今天的06:30到明天的06:29每分钟数。因为我需要用它制作图表。

这是我当前的查询：

;WITH RESULT AS (SELECT 
  TT.productcode
, MaxValueThatday          = max(maxval.MAXVALUE )              
, MaxValueBefore630NextDay = max(MAXValBefore630.MAXVALUE)
, ResultSubstraction = 
 CASE WHEN max(maxval.MAXVALUE ) <>  max(MAXValBefore630.MAXVALUE)
        THEN max(maxval.MAXVALUE )  - max(MAXValBefore630.MAXVALUE)
    ELSE max(maxval.MAXVALUE ) 
END
FROM  [dbo].my_table TT
OUTER APPLY(   
            SELECT max(value) MAXVALUE
                , product_code 
             FROM [dbo].my_table aa
                WHERE Aa.productcode = tt.productcode
            group by productcode
        )maxval
OUTER APPLY(   
            SELECT max(A.value) MAXVALUE
                , productcode
             FROM [dbo].my_table A
                 WHERE DATEPART(HOUR,date) <= 6 AND DATEPART(MINUTE,date) < 30 
                 and A.productcode = tt.productcode
            group by productcode
        )MAXValBefore630
where    ( date> DATEADD(MINUTE,390,CAST({ fn CURDATE()} AS DATETIME) ) ) --6:30 today
group by tt.productcode

)
SELECT SUM(ResultSubstraction)
FROM RESULT

那么，如何从今天的06:30到明天的06:29，每分钟计算总价值？

重要说明是：

  1. 该值应从06:30开始计数。

  2. 如果在06:30时值为0，那么无需将值与上一行（值）求和，只需将当前值包括在Expectedvalue列中即可。

  3. 如果在06:30时该值不为0，那么我们需要在当前行（06:30）-值当前行-1（06:29）中进行赋值。结果应包含在“期望值”列中。然后，我们需要使用以下公式对每一行进行求和：（当前值-当前值-1）+当前期望值。
  4. 如果当前值（当前行）与上一行相同，则无需将它们求和。只需使用当前的期望值即可。

我的解释清楚了吗？

我希望大家都明白我的意思，并希望帮助我摆脱困境。

非常感谢您的帮助。

初始答案：

只需使用CROSS APPLY并在SUM上进行value 

SELECT ID, DATE, VALUE, VALUEEXPECTED
FROM  [dbo].my_table TT
      CROSS APPLY
      (
          SELECT SUM (VALUE) AS VALUEEXPECTED
          FROM   [dbo].my_table AS X
          WHERE  X.ID   <= TT.ID
          AND    X.DATE > DATEADD(MINUTE,390,CAST({ fn CURDATE()} AS DATETIME) ) )
      ) AS VE

新答案：

对于问题的更改，这是一种计算期望值的新方法。

select  t.*, 
        expectedvalue = t.value - isnull(s.value, 0),
        -- the following 3 value are included for your reference on how the query works
        r.ref_date, s.date, s.value
from    my_table t
        cross apply
        (
            -- calculate the reference 06:30 date & time for each date
            select  ref_date = dateadd(day, datediff(day, 0, dateadd(minute, -390, t.[date])), '06:30')
        ) r
        outer apply
        (
            -- get the last value before 06:30 ref date
            select  top 1 x.date, value = x.value
            from    my_table x
            where   x.id     < t.id
            and     x.[date] < r.ref_date
            order by x.date desc
        ) s
