sir, i have a sql query that give output like :-

SQL QUERY:
SQL
select courseid,semid,roomno,studentid from matrix
where courseid=1493 and semid=3
union all
select courseid,semid,roomno,studentid from matrix
where courseid=1493 and semid=5



Output:-
SQL
CourseID  Semid Roomno StudentID
 [1493]          [3]  [A-307]     [1012]
 [1493]          [3]  [A-307]     [1013]
 [1493]          [3]  [A-307]     [1014]   
 [1493]          [5]  [B-405]     [1145]  
 [1493]          [5]  [B-405]     [1146]

but i need output like :-

SQL
CourseID  SemID RoomNo StudentID   CourseID SemID  RoomNo StudentID
 [1493]   [3]  [A-307]     [1012]   [1493]      [5]      [B-405]     [1145]
 [1493]   [3]  [A-307]     [1013]   [1493]      [5]      [B-405]     [1146] 
 [1493]   [3]  [A-307]     [1014]

It is not at all clear how you want to join the two sets of data - why do you say
[1493] [3] [A-307] [1012] [1493] [5] [B-405] [1145]
but not
[1493] [3] [A-307] [1012] [1493] [5] [B-405] [1146]?

Why not just use a join rather than Union?
Shweta N Mishra 18-Nov-14 3:22am    
what is the data contained in each table ?, Di you tried Join on both table
TCS54321 18-Nov-14 5:25am    
this is a single table. and i tried join but its not give right output..

What about this?

SQL
SELECT
    R1.CourseId,
    R1.SemId,
    R1.RoomNo,
    R1.RowNumber,
    R2.CourseId,
    R2.SemId,
    R2.RoomNo,
    R2.RowNumber
FROM
    (SELECT *, ROW_NUMBER() OVER (ORDER BY CourseId) 'RowNumber' FROM #Matrix WHERE CourseId = 1493 and SemId = 3) AS R1
    FULL OUTER JOIN
    (SELECT *, ROW_NUMBER() OVER (ORDER BY CourseId) 'RowNumber' FROM #Matrix WHERE CourseId = 1493 and SemId = 5) AS R2
    ON
    R1.RowNumber = R2.RowNumber

thx!
Helo Dude Try This ....

SQL
Declare @matrix AS TABLE (courseid NVARCHAR(10),semid  NVARCHAR(10),roomno  NVARCHAR(10),studentid  NVARCHAR(10))


INSERT INTO  @matrix (courseid,semid,roomno,studentid) VALUES
                      ('[1493]','[3]','[A-307]','[1012]')
INSERT INTO  @matrix (courseid,semid,roomno,studentid) VALUES
                      ('[1493]','[3]','[A-307]','[1013]')
INSERT INTO  @matrix (courseid,semid,roomno,studentid) VALUES
                      ('[1493]','[3]','[A-307]','[1014]')

INSERT INTO  @matrix (courseid,semid,roomno,studentid) VALUES
                      ('[1493]','[5]','[B-407]','[1045]')
INSERT INTO  @matrix (courseid,semid,roomno,studentid) VALUES
                      ('[1493]','[5]','[B-407]','[1046]')



;WITH Hierarchy(CourseID3,SemID3,RoomNo3,StudentID3,CourseID5,SemID5,RoomNo5,StudentID5)
AS
(
SELECT courseid,semid,roomno,studentid,'','','','' FROM @matrix WHERE semid = '[3]'
union ALL
SELECT '','','','',courseid,semid,roomno,studentid FROM @matrix WHERE semid ='[5]'

)


SELECT CourseID3 [courseid],
       SemID3 [semid],
       RoomNo3 [roomno],
       StudentID3 [studentid],
       CourseID5 [courseid],
       SemID5 [semid],
       RoomNo5 [roomno],
       StudentID5 [studentid]  FROM Hierarchy

You could do PIVOT after getting Union result, which you used earlier

check this .need help in sql query..[^]

and other way is

SQL
SELECT  CourseID=MAX(A.CourseID), SemID=MAX(a.SemID), RoomNo=mAX(a.roomNO), A.StudentID ,
CourseID=MAX(B.CourseID), SemID=MAX(B.SemID), RoomNo=mAX(B.roomNO),B.StudentID
FROM
(
select courseid,semid,roomno,studentid from #matrix
where courseid=1493 and semid=3
) A
full outer join
(
select courseid,semid,roomno,studentid from #matrix
where courseid=1493 and semid=5
) b on A.courseid=b.courseid --AND A.SEMID=b.SEMID
gROUP BY A.StudentID,B.StudentID



But it would not give you exact result you wanted.

tnx for ur effort shweta ji.. i am using both solutions. but not getting right output.
Manas Bhardwaj 18-Nov-14 6:43am    
Hi Shewta, This is not what OP wants. Please see my answer.
King Fisher 18-Nov-14 6:45am    
Instead of your Query you can do this way :)

select *From (select courseid,semid,roomno,studentid from matrix
where semid=3)t1 ,

(select courseid,semid,roomno,studentid from matrix
where semid=5)t2
Shweta N Mishra 18-Nov-14 6:57am    
Ok yes you can try this


select *
FROM
(
select courseid,semid,roomno,studentid,ROW_NUMBER() Over ( Order BY studentid) RowID from #matrix
where courseid=1493 and semid=3
) A
full outer join
(
select courseid,semid,roomno,studentid,ROW_NUMBER() Over ( Order BY studentid) RowID from #matrix
where courseid=1493 and semid=5
) b on A.RowID=b.RowID --AND A.SEMID=b.SEMID

and i see you already have same solution from manas.
my +5 to him
