Try something like:
    select r.*, count(*) from roster r, roster_staff s    where rsdate = rodate and rsgid = rogid and rsgsid = rogid
groupby r.*
 

or
    select r.*, (select count(*) from roster_staff s    where rsdate = rodate and rsgid = rogid and rsgsid = rogid    )
rosterr
 

May not be exactly right, but you should get the idea
