Как объединить два запроса в один результат с разными столбцами и условиями

---

запроса query1:-

Select expen.schemeno, sum(expen.amount) as Premonth,sch_mas.disp,sch_mas.sch_amount,
 sch_mas.san_no , CONVERT(varchar, sch_mas.sdate, 106)as schdate  from [dbo].[expen] inner join
  sch_mas on expen.schemeno=sch_mas.sch_no  where schemeno='W2/2013/11516' and exp_date<'2013-04-01' and 
  passingDate is not null group by sch_mas.disp, expen.schemeno,sch_mas.sch_amount,sch_mas.sdate,sch_mas.san_no

Query2:-

Select monyr, SUM(expen.amount) as expenamt,schemeno from expen  where exp_date>'2013-03-31' and exp_date<'2014-03-31' and schemeno='W2/2013/11516' group by monyr,schemeno

Что я уже пробовал:
