average

Hi,

I want to do an average : the problem is for 1 item i'm calculating the AVG of each elements (working) but as soon as i want the GLOBAL average the average of the elements (something and foo) it doesn't work.

I need to do that because i want to sort the result by the global average

SELECT AVG(AVG(something)+AVG(foo)) /2 as moy
..... 
ORDER BY moy DESC

Thanks,
