Sure!  I do it like this:

count = ksdbh.count(:Tablename) {|r| r.user_id == 7}

Other people probably do it differently, though.  Details are important 
when asking a "How do I...?" question.

I imagine that you are actually asking how to do that using ActiveRecord, 
right?  If so, while you will probably get a correct answer for AR from 
someone on this list, the better place to ask those questions is the Rails 
list.
