Display rows from MySQL where a datetime is within the next hour

Question

I always have trouble with complicated SQL queries.

This is what I have

$query = \'
            SELECT id,
                   name, 
                         


        

Answer 1

WHERE date_time = DATE_SUB(NOW(), INTERVAL 1 HOUR)

means date_time equals exactly now minus one hour, which would result in any record exactly one hour old.

Why not use

WHERE TIMEDIFF(date_time, NOW()) < '01:00:00'
AND date_time > NOW()
