Extract of maximum value of an ID for each line containing date range

Hello,
Hours passed and whereas I looked many posts on the web, I don't find any source of help to resolve my problem.
I wish to make data treatment in order to extract of maximum value of an ID for each line containing date range. Sometimes, graphics tell more that text, you will find it in attachment!

For that, I've already created a new view that out a date range (start/end) of a specific phase for each production Batch.
Then, I would like to extract a Max Value for Tagname ID in history table for each Batch, using the date range and the tagname.

Today my request is the following but if there is no error (youpi), there is no results! :smile:

SELECT        dbo.V_DatesRincagesNep.Batch_Log_ID, dbo.V_DatesRincagesNep.DateTimeStart, dbo.V_DatesRincagesNep.DateTimeEnd, MAX(Runtime.dbo.v_History.Value) AS MaxValCond
FROM            dbo.V_DatesRincagesNep LEFT OUTER JOIN
                         Runtime.dbo.v_History ON Runtime.dbo.v_History.DateTime BETWEEN dbo.V_DatesRincagesNep.DateTimeStart AND dbo.V_DatesRincagesNep.DateTimeEnd
GROUP BY dbo.V_DatesRincagesNep.DateTimeStart, dbo.V_DatesRincagesNep.DateTimeEnd, dbo.V_DatesRincagesNep.Batch_Log_ID, Runtime.dbo.v_History.TagName
HAVING        (Runtime.dbo.v_History.TagName = 'NE5547_CIT_320.fMesure')

The sample data are following:

My training and experiences are limited in SQL, and this subject is complex so I hope that I will find help!
Thank you very much for attention!

Pictures are great for seeing what you have/want, but without DDL and sample data. you're asking us to provide it for you. We can only guess at exactly what you have

Hi Mike,
Thank for your response, I have edited my post and corrected the display of my request, I don't know if it is what you expect, the copy-past of the data is relatively the same that in my picture, then I represent in my picture only the ID I want to filter !
I have currently build the "Batch table" with each one date range, but I cannot build a new table with MaxValue for a same Tagname ID for each Batch Log ID

I think the main difficulty for me is that the history table contains values ‚Äč‚Äčassociated with several pieces of data (Tagname ID) and it is the association "between date range" + "Tagname" that I do not understand.

Here's a start, but your history data is not within your range data, so the sample data is useless

create table #history (historyDate datetime, tagName varchar(50), TagValue decimal(30,20))
insert into #history values
('2024-05-06','NE5547_FIT_003.fMesure',-0.00520833348855376),

Thank you very much but I think we don't understand each other for my need!

Indeed, my sample data is not suitable because my tables contain a lot of historical data.
The "batches" table contains 67 rows for the last month.
For a single row (=1 batch) for example, the below exemple DateTime range is approximately 14 minutes.

SELECT TOP (10) [Batch_Log_ID]
      ,[UnitOrConnection]
      ,[DateTimeStart]
      ,[DateTimeEnd]
  FROM [MERCK_PAS_MB].[dbo].[V_DatesRincagesNep]
  where [DateTimeStart] BETWEEN DATEADD(DAY, 1, EOMONTH(GETUTCDATE(), - 2)) AND EOMONTH(GETUTCDATE(), -1)

If I report this targeted range on my specific tagname and in the associated date-time range, I obtain 166 rows, of which I wish to extract the max.

exemple here for top 20 rows

SELECT top(20) [DateTime]
      ,[TagName]
      ,[Value]
  FROM [Runtime].[dbo].[v_History]
  where TagName = 'NE5547_CIT_320.fMesure' and [DateTime] between '2024-04-03 09:40:21.000' and '2024-04-03 09:54:15.000'

Then i need to extract Max Value

/*Extract*/
1.72453701496124

Finally, the request on my first post is to extract this MaxValue for each "BatchList" row in a new table.

this is why YOU need to provide readily consumable ddl and data so that we can help. We are guessing at what you need. If you can provide the data that is relevant to your issue then we can help, otherwise you're going to get alot of this back and forth. It doesn't have to be real data, just something that represents your issue and works (i.e. dates align).

Sorry I don't really know how to export DDL as requested..
I finally resolve my issue with a PowerShell script exporting CSV with sucessive each loop.
Thank you.
