Try something like:

select r.*, count(*) from roster r, roster_staff s
where rsdate = rodate and rsgid = rogid and rsgsid = rogid
group by r.*

or

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

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