transpose rows to columns in sql - sql

Question

I have problem in getting the desired output with the SQL query.
My sql data is as follows:
TOTAL Charge PAYMNET A B C D E MonthYear
------- ----------- ----------- --------- -------- ---------- ------- ------- ----------
661 157832.24 82967.80 700.00 10.70 58329.33 0.00 0.00 Oct-2013
612 95030.52 17824.28 850.00 66.10 53971.41 0.00 0.00 Nov-2013
584 90256.35 16732.91 700.00 66.10 52219.87 0.00 0.00 Dec-2013
511 72217.32 12336.12 285.00 53.17 42951.12 0.00 0.00 Jan-2014
I need the output as follows,
Data Jan-2013 Feb-2013 Mar-2013
TOTALCOUNT 761 647 671
Charge 126888 119995 151737.5
Payment 25705.4 26235.47 28704.41
A 1089.08 1020 745
B 2100.4 1947.25 1868.22
C 94246.55 84202.15 115673.7
D 0 0 0
E 0 0 0
I have seen the examples of pivot and unpivot, in pivot I don't get the column headers as row data, and in unpivot I didn't found an example where I can transpose multiple columns. I have another option to get this result in the code. But I want to know is it possible to get this kind of result in sql?
Edit
The result will give only for 3 or 4 months, not more than that.
Update : The first sample data is the actual data which I will get as a result of multiple joins and grouping on multiple tables, which I will store into a temp table. I tried to get the required result by modifying the query which is not possible because of the table structure. I managed to get the result as in the first sample data, but this is not what the client want to see!!! So I need to process the temp table data which will be only 3 to 4 rows into required output. The query to get the first result is select * from temp. The processing needs to be done on temp table result.
Update-2
I have tried the following query
declare #cols varchar(max)
select #cols = STUFF((select ', ' + MonthYear
from #tmp for xml path('')),1,1,'')
declare #query varchar(max)
set #query =
'select ''TOTAL'' as Data,' +#cols+' from
(select MonthYear,TOTALCLAIMS from #tmp)st
pivot
(
MAX(TOTAL) for MonthYear in (' + #cols + ')
)pt;'
Which gave me the first row correctly!!! But I tried to use union as
set #query =
'select ''TOTAL'' as Data,' +#cols+' from
(select MonthYear,TOTALCLAIMS from #tmp)st
pivot
(
MAX(TOTAL) for MonthYear in (' + #cols + ')
)pt;
union
select ''CHARGES'' as Data,' +#cols+' from
(select MonthYear,TOTALCLAIMS from #tmp)st
pivot
(
MAX(CHARGES) for MonthYear in (' + #cols + ')
)pt;'
Which gives an error as incorrect syntax near union. Any one know how to union pivot results? Or is there any better way to do this?
Thank You.

I have tried this code. Please check and let me know if it works
I know that it doesnt look so good. Also not sure how it will be performance wise.
--Can have more columns like A,B,...
DECLARE #tbl TABLE
(
TOTAL INT,
CHARGE FLOAT,
PAYMENT FLOAT,
MONTHYEAR VARCHAR(50)
)
--Test data
INSERT INTO #tbl SELECT 661, 157832.24, 82967.80, 'Oct2013'
INSERT INTO #tbl SELECT 612, 95030.52, 17824.28, 'Nov2013'
INSERT INTO #tbl SELECT 584 ,90256.35, 16732.91, 'Dec2013'
--Can be a physical table
CREATE TABLE #FinalTbl
(
DATA VARCHAR(100)
)
--inserted hardcode records in data column. To add it dynamically you would need to loop through information_schema.columns
--SELECT *
--FROM information_schema.columns
--WHERE table_name = 'tbl_name'
INSERT INTO #FinalTbl
VALUES ('TOTAL')
INSERT INTO #FinalTbl
VALUES ('CHARGE')
INSERT INTO #FinalTbl
VALUES ('PAYMENT')
DECLARE #StartCount INT, #TotalCount INT, #Query VARCHAR(5000), #TOTAL INT,#CHARGE FLOAT,#PAYMENT FLOAT,#MONTHYEAR VARCHAR(50)
SELECT #TotalCount = COUNT(*) FROM #tbl;
SET #StartCount = 1;
WHILE(#StartCount <= #TotalCount)
BEGIN
SELECT #TOTAL = TOTAL,
#CHARGE = CHARGE,
#PAYMENT = PAYMENT,
#MONTHYEAR = MONTHYEAR
FROM
(SELECT ROW_NUMBER() over(ORDER BY MONTHYEAR) AS ROWNUM, * FROM #tbl) as tbl
WHERE ROWNUM = #StartCount
SELECT #Query = 'ALTER TABLE #FinalTbl ADD ' + #MONTHYEAR + ' VARCHAR(1000)'
EXEC (#Query)
SELECT #Query = 'UPDATE #FinalTbl SET ' + #MONTHYEAR + ' = ''' + CONVERT(VARCHAR(50), #TOTAL) + ''' WHERE DATA = ''TOTAL'''
EXEC (#Query)
SELECT #Query = 'UPDATE #FinalTbl SET ' + #MONTHYEAR + ' = ''' + CONVERT(VARCHAR(50), #CHARGE) + ''' WHERE DATA = ''CHARGE'''
EXEC (#Query)
SELECT #Query = 'UPDATE #FinalTbl SET ' + #MONTHYEAR + ' = ''' + CONVERT(VARCHAR(50), #PAYMENT) + ''' WHERE DATA = ''PAYMENT'''
EXEC (#Query)
SELECT #StartCount = #StartCount + 1
END
SELECT * FROM #FinalTbl
DROP TABLE #FinalTbl
Hope this helps

I would imagine the reason you are only getting 3 or 4 months is because you don't have data for the missing months? If you want to display columns for missing months you will need to either:
Create a Table datatype with all the months you want to display
and left join the remainder of the tables to it in your query. You
could then use the PIVOT function as normal.
If you know how many columns up front i.e. one for each month in a particular year and it won't change, you can simply use CASE
Statements (one for each month) to transpose the data without the
PIVOT operator.
I can provide examples if needed.

Select Month(Mdate)md,'A' AS Col,sum(A) as a from Product group by Month(MDate)
union all
Select Month(Mdate)md,'B',sum(b) as a from Product group by Month(MDate)
union all
Select Month(Mdate)md,'C',sum(c) as a from Product group by Month(MDate)
union all
Select Month(Mdate)md,'D',Count(A) as a from Product group by Month(MDate)
Try Pivot with the above query you may to get required result....
