This message has been marked as the solution to the initial question of the thread.
>Trying to figure out how to return just 1 record for each date in the results. In the attached screen shot, you'll see there are a total of 5 records, one with a TransactionDT of 10-06-2010 and 4 with dates on 10-04-2010. I'd like to return from the query, just the latest record from each date. So in this case it would only return 2 records, 1 for the 6th and 1 for the 4th.

Take a look at

Including an Aggregated Column's Related Values - Part 2

One of the solutions:
SELECT pathwID,Height,HeightMeasureType,Weight,WeightMeasureType,InputSource,TransactionDT,
              UserID,NoteID,BMI,MeasureStatus,Meetingnumber
FROM dbo.co_Pat_HeightWeightHistory H
WHERE patientID=@PatientID
and H.ID = (select top 1 ID from dbo.co_Pat_HeightWeightHistory H1 where H1.pathwID = H.PathwID order by TransactionDT DESC)
ORDER BY PathwID Desc
If it's not broken, fix it until it is.
