每隔06:30 SQL Server查询计数值

请帮我。 我的数据和查询有问题。 请先看看我的桌面设计。

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，所有数据都是在每分钟从机器获得的。

我想从今天06:30到明天06:29每分钟计算一次价值。 因为我需要从中制作图表。

这是我目前的查询：

 ;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)  DATEADD(MINUTE,390,CAST({ fn CURDATE()} AS DATETIME) ) ) --6:30 today group by tt.productcode ) SELECT SUM(ResultSubstraction) FROM RESULT 

那么，如何计算每分钟的总价值从今天06:30开始到明天06:29？

重要的说明是：

1. 该值应从06:30开始计算。

2. 如果在06:30该值为0，则不需要将值与前一行（值）相加，只需将当前值包含在expectedvalue列中。

3. 如果在06:30该值不为0，那么我们需要在当前行（06:30）中进行值 – 值当前行-1（06:29）。 结果应包含在expectedvalue列中。 然后我们需要使用公式在每一行中对它们求和:(当前值 – 当前值-1）+当前预期值。
4. 如果当前值（当前行）与前一行相同，则无需对它们求和。 只需使用当前的期望值。

我的解释清楚了吗？

我希望你们所有人都明白我的意思，并希望帮助我解决问题。

非常感谢你的帮助。

Answer 1

初步答案：

只需使用CROSS APPLY并对value执行SUM

 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，计算预期值的新方法。

 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
