SQL Join to get most recent record

Question

I have three tables:

• Measurements (MeasureID, Time, Distance, Value)
• Events(EventID, Time Value)
• EventValues

Answer 1

You can use CROSS APPLY.

SELECT  
    M.*, Data.* 
FROM [Measure] M 
CROSS APPLY
     (SELECT TOP 1 EV.* FROM [Event] E JOIN EventValues EV ON E.EventID = EV.EventID  
     WHERE M.Time >= E.Time ORDER BY E.Time DESC) AS Data
ORDER BY M.Distance
