Combine two rows in single column data

Question

hi,
I have an requirement
for ex:
Division              Resourcename   PRojectname    Projectstartdate           Projectenddate    allocated percentage
development           A                     one                    '01/01/2014'           '03/31/2014'  
           100%
development           B                     one                    '01/01/2014'           '03/31/2014'  
            100%
development           C                    one                    '01/01/2014'           '03/31/2014'  
            100%
development           D                    one                    '01/01/2014'           '03/31/2014'  
            100%
development           E                   one                    '01/01/2014'             '01/31/2014'  
                25%
development           E                  one                    '02/01/2014'             '03/31/2014'  
                25%
In the above "Resource E have multiple dates ,will work on separate dates on single project,but the resource allocated percentage will be always same(ie)=25%,so the report output look like
Division              Resourcename   PRojectname    Projectstartdate           Projectenddate    allocated percentage
development           A                     one                    '01/01/2014'           '03/31/2014'  
           100%
development           B                     one                    '01/01/2014'           '03/31/2014'  
            100%
development           C                    one                    '01/01/2014'           '03/31/2014'  
            100%
development           D                    one                    '01/01/2014'           '03/31/2014'  
            100%
development           E                   one                    '01/01/2014'             '01/31/2014'
               25%
       '02/01/2014'             '03/31/2014'              
the above SSRS report output look after grouping on division,resource.
this same output i need from sql query.how to achieve this.
Thanks

Bhupesh, I do not have any idea how your actual data would look like. So the below snippet can
only taken as reference not as an actual.
[Join condition, CASE...WHEN everything would change as per your actual data]
Try the below:
create table Bhupesh_test(Division varchar(50), Res_Name varchar(50), Proj_Name varchar(50), startdate date, enddate date, allocated int)
Insert into Bhupesh_test Values
('development','A','one', '01/01/2014','03/31/2014',100),
('development','B','one', '01/01/2014','03/31/2014',100),
('development','C','one', '01/01/2014','03/31/2014',100),
('development','D','one', '01/01/2014','03/31/2014',100),
('development','E','one', '01/01/2014','01/31/2014',25),
('development','E','one', '02/01/2014','03/31/2014',25)
;With cte
as
Select *, ROW_NUMBER()OVER(Partition by Division,Res_Name,Proj_Name Order by startdate)Rn
From Bhupesh_test
Select Division,Res_Name,Proj_Name,startdate,enddate,allocated From
Select Case when A.Division = B.Division and A.Res_Name = B.Res_Name and A.Proj_Name = B.Proj_Name
and A.startdate <>B.startdate Then NULL Else A.Division end Division,
Case when A.Division = B.Division and A.Res_Name = B.Res_Name and A.Proj_Name = B.Proj_Name
and A.startdate <>B.startdate Then NULL Else A.Res_Name end Res_Name,
Case when A.Division = B.Division and A.Res_Name = B.Res_Name and A.Proj_Name = B.Proj_Name
and A.startdate <>B.startdate Then NULL Else A.Proj_Name end Proj_Name,
Case when A.Division = B.Division and A.Res_Name = B.Res_Name and A.Proj_Name = B.Proj_Name
Then A.startdate Else B.startdate end startdate,
Case when A.Division = B.Division and A.Res_Name = B.Res_Name and A.Proj_Name = B.Proj_Name
AND A.startdate <> B.startdate Then A.enddate Else B.enddate end enddate,
Case when A.Division = B.Division and A.Res_Name = B.Res_Name and A.Proj_Name = B.Proj_Name
and A.startdate <>B.startdate Then NULL Else A.Allocated end Allocated,1 Ordered
From cte A
Inner join cte B on A.Rn = B.Rn+1 and A.Res_Name = B.Res_Name
Union All
Select Division,Res_Name,Proj_Name,startdate,enddate,allocated,0 From cte A where Rn=1
) A
Order by Ordered
Drop table Bhupesh_test
