I write two queries to get the 2 datasets equilvalent from two tables which are joined with geo table. How to get it as one set. so that we can get the one set.


Select X.State,X.District,X.Source,X.Res,Y.Cum_res From

(select geotable.state,geotable.district,geotable.source,sum(isnull(mstchvs.flagr,0)) as  res
from geotable
left join mstchvs
ON geotable.state=mstchvs.state and geotable.district=mstchvs.district and geotable.source=mstchvs.source
and flagr=1 and dateadd(dd,0,DATEDIFF(dd,0,rfeeddate)) >= CONVERT(DATETIME,@fd) and
dateadd(dd,0,DATEDIFF(dd,0,rfeeddate)) <= CONVERT(DATETIME, @td)
--rfeeddate>='2012-3-1' and rfeeddate<='2012-3-31'
group by geotable.state,geotable.district,geotable.source
) X
inner join
(
select geotable.state,geotable.district,geotable.source,sum(isnull(mstchvs.flagr,0)) as cum_res
from geotable
left join mstchvs
ON geotable.state=mstchvs.state and geotable.district=mstchvs.district and geotable.source=mstchvs.source
and flagr=1 and dateadd(dd,0,DATEDIFF(dd,0,rfeeddate)) <= CONVERT(DATETIME, @td)
group by geotable.state,geotable.district,geotable.source
) Y
on X.state = Y.state and X.district = Y.district and X.source = Y.source



Select X.State,X.District,X.Source,X.Res,Y.Cum_res From

(select geotable.state,geotable.district,geotable.source,sum(isnull(mstchvs.flagpre,0)) as  res
from geotable
left join mstchvs
ON geotable.state=mstchvs.state and geotable.district=mstchvs.district and geotable.source=mstchvs.source
and flagpre=1 and dateadd(dd,0,DATEDIFF(dd,0,prefeeddate)) >= CONVERT(DATETIME,@fd) and
dateadd(dd,0,DATEDIFF(dd,0,prefeeddate)) <= CONVERT(DATETIME, @td)
--prefeeddate>='2012-3-1' and prefeeddate<='2012-3-31'
group by geotable.state,geotable.district,geotable.source
) X
inner join
(
select geotable.state,geotable.district,geotable.source,sum(isnull(mstchvs.flagpre,0)) as cum_res
from geotable
left join mstchvs
ON geotable.state=mstchvs.state and geotable.district=mstchvs.district and geotable.source=mstchvs.source
and flagpre=1 and dateadd(dd,0,DATEDIFF(dd,0,prefeeddate)) <= CONVERT(DATETIME, @td)
group by geotable.state,geotable.district,geotable.source
) Y
on X.state = Y.state and X.district = Y.district and X.source = Y.source

UNION query perhaps?  If your output fields are the same in the two queries (and they are the same data types), you should be able to use a UNION.

I dont have to fetch common rows.
I want to use CTE.
here geotable is the common table that contain 48 districts. For these districts values are entered in these two tables.
So the queries shows the result reparately with the base table as geo table.
I wanto merge that,

OK, wanting to use CTE wasn't clear from your original question, so UNION isn't for you!  I don't have any practical experience of using CTEs although I appreciate the concept as I have used table variables before.  If you want to use multiple CTEs (one for each query) in one select statement, then consider the following links:

Hope this helps or at least provides a pointer to where you wish to go!
