I'm using the following query and it's getting logged to the slow queries log. Is there a more efficient way of retrieving the data.
select SQL_CACHE code,minprice from thetable where code in ('a','b','c','d','e','f') order by minprice

have you tried using EXPLAIN?

I have used EXPLAIN and it shows the indexes are used but it's still very slow, 4.8 seconds to return results, that's why I was wondering if there is a more efficient way than using the IN clause.
