Hi, I have a table that contains call records. I'm looking to get only records for users who made the most calls over a particular time duration in an efficient way. calls() time, duration, caller_number, dialed_number -- query to get top 10 callers select caller_number, count(1) from calls group by caller_number order by calls desc limit 10 --my current query to get those callers select * from call where caller_number in (above query) It works but I was hoping for something a little more efficient if anyone has an idea.
