  hi

  you can check the below sample query for getting the sum

  select companyname ,(select sum(freight) from orders where orders.customerid = customers.customerid) as frieght
  from customers

  in your case it will 

  select schoolname ,(select sum(noofseat) from roommaster where roommaster.schoolid=SchoolMaster.schoolid) as TotalNoofSeat from SchoolMaster

  Hope it helps,thanks
