what is the deal with GROUP BY?

[_underdog]

Every time I run a query with GROUP BY in mySQL it nearly brings my server to it's knees. Is this just a mySQL thing? Should I just try and stay completely away from any queries using GROUP BY?

it's not a mysql thing, i've never had any problems with it before. maybe its just how your server is configured. what box are you running it on?
