Hi All
I have SQL table like below

Rack  Cell  Qty
A1     X     20
A2     Y     30
A3     Z     40
B1     X     59
B2     Z     60
C1     X     70

Now my question is how I can display the table like below

   X  Y  Z
A1
A2
A3
B1
B2
C1

In original table X, Y, Z is more then one time but new table it shows only one time each

Thanks to All

Your expected table and the requirements you mentioned doesnt match

Depends on the version of SQL Server you are using. For SQL 2005 and later you want to use PIVOT.

For more details see:
http://www.mssqltips.com/sqlservertip/1019/crosstab-queries-using-pivot-in-sql-server-2005/[^]

This way you are not hardcoding the number of cells - if that grows the table of results automatically gets an extra column. Very similar to the CROSSTAB query in MS Access.

SQL

select distinct A.Rack,
 (select B.Qty from temp B  where B.Rack =A.Rack and B.Cell like '%X%') as 'X',
 (select B.Qty from temp B  where B.Rack =A.Rack and B.Cell like '%Y%') as 'Y',
 (select B.Qty from temp B  where B.Rack =A.Rack and B.Cell like'%Z%') as 'Z'
from temp A

Solution 1

Try this. It is not tested so if any problem please reply.

SQL

select A.Rack,
 (select Sum(B.Qty) from tablename B  where B.Rack =A.Rack and B.Cell ='X') as 'X',
 (select Sum(B.Qty) from tablename B  where B.Rack =A.Rack and B.Cell ='Y') as 'Y',
 (select Sum(B.Qty) from tablename B  where B.Rack =A.Rack and B.Cell ='Z') as 'Z',
 Count(A.Rack)
from tablename A
group by A.Rack

Yes Sir it is working but if A1 has x,y,z three value then it shows three rows but I need in one row and if you little explain how it works then it will help me lot in future.
Thanks a Lot

Can you explain this requirement?What i understand is
Rank Cell
A1 X,Y,Z
After that what you want?

IndrajitDasgupat 2-Aug-12 2:32am

My original table is like below
Rack cell qty
A1 X 20
A1 Y 30
A1 Z 40
B1 X 70
B1 Y 60
C1 Z 34
C1 z 22

Now my table should display like below
Rack X Y Z
A1 20 30 40
B1 70 60 Null
C1 Null Null 56

Thanks

What ouput currently it is giving?

IndrajitDasgupat 2-Aug-12 2:48am

Currently it is giving like below
Rack X Y Z
A1 20 30 40
A1 20 30 40
A1 20 30 40
B1 70 60 Null
B1 70 60 Null

So A1 it should come one line and B1 also should also in one line
and moreover C1 should display like below
C1 Null Null 56
Thanks

Try my updated answer. I have used group by on Rack which will collect all same Rack in singli position.

IndrajitDasgupat 2-Aug-12 3:03am

Yes it is working but C1 rack is not able to add
C1 Z 34
c1 z 22
and not able to display like below

C1 Null Null 56
it shows error

Thanks

pradiprenushe 2-Aug-12 3:24am

See updated answer.
I have added sum function. You are getting error because your subquery returning more than one rows.

IndrajitDasgupat 2-Aug-12 4:46am

Yes Sir your code is working fine
here Rack i.e. A1,B1,C1 if I add another one D1 in database table it takes automatically
But in the case cell i.e X,Y,Z if I add another cells in table like M,N,...,O,P then it is not adding automatically what should for that

Thanks for your Great help

Normally your database design is done with good analysis. So it is rarely required change. When design change its dependent part also change. So when you change table change sp to handle for D as like others.
