Adding AVG(Price) into a mySQL query?

Question

I have the following query

$query = "SELECT * FROM used ".$conditionString." ORDER BY id DESC LIMIT $offset, $rec_limit";

But now I want to know also the average price of the returned rows

AVG(Price) AS PriceAverage

How to do this?

Answer 1

this should work for you:

$query = "SELECT *,AVG(Price) FROM used ".$conditionString." ORDER BY id DESC 
GROUP BY id WITH ROLLUP 
LIMIT $offset, $rec_limit";
