umm...that depends. for instance:

[!--coloro:blue--][span style=\"color:blue\"][!--/coloro--] select count(columnnamehere) as total from tablename[!--colorc--][/span][!--/colorc--]



where x is the total returned from count()

Please, take the time and do some research and find out how much it would have cost you to get your help from a decent paid-for source. A "roll-of-the-dice" freelancer will charge you $5-$15/hr. A decent entry level freelancer will charge you around $15-30/hr. A professional will charge you anywhere from $50-$100/hr. An agency will charge anywhere from $100-$250/hr. Think about all this when soliciting for help here. Think about how much money you are making from the work you are asking for help on. No, we do not expect you to pay for the help given here, but donating a few bucks is a fraction of the cost of what you would have paid, shows your appreciation, helps motivate people to keep offering help without the pricetag, and helps make this a higher quality free-help community :)

You're not supposed to be able to at all -- this is an aggregate function, and hence requires something aggregate to work on. MySQL just assumes that you implicitly mean the entire result set, but you shouldn't rely on this.
Seriously... if people don't start reading this before posting, I'm going to consider not answering at all.
