I have looked through TechNet and SQL Server Central for a good way to pivot a difficult table. So far, the many different approaches have failed and I need a fresh perspective and help with the code.

I will provide the table language below.

The need is to output a table that will show a salespersons name with the Gross Profit each made in a month for the last 12 months (including the current) and then to take the GP made in the month from the current year and subtract from the GP made in the same month of the prior year.

One of the problems is that the salespersons do not all have the same data available for the same range; but the months must line up in order. So if a salesperson has no data for a month it should be NULL. However, every Month1,Month2,Month3, etc needs to be the same actual month year. So, just iterating through them does not work as the "month1" for someone with data in November as the earliest is not the same as the "month1" for someone with October as the earliest available.

The environment is SQL Server 2008 R2.

The table created will be used as a data source in SSRS 2008 R2.

Sample results:

StartDate: 11/01/2013
EndDate: 11/30/2013

M1 = 11/2013
M2 = 10/2013
M3 = 9/2013
...
M12 = 11/2012

CY = current year
PY = prior year

YOYGPDiff = Year Over Year Gross Profit Diff (CY - PY)

[names] [date per month CY] [Monthly GrossProfit CY] [date per month PY] [Monthly GrossProfit PY] [Monthly YOYGPDiff]

Name, DATE_CY1, MonthlyGP_CY1, DATE_PY1, MonthlyGP_PY1, YOYGPDiff_M1, ...
BOB BELL, 11-01-2013, 1333.650000, 11-01-2012, 10969.280000, -9635.630000, ...


DATE_CY12, MonthlyGP_CY12, MonthlyGP_PY12, YOYGPDiff_M12
11-01-2012, 10969.280000, 11254.240000, -284.960000



Name, DATE_CY1, MonthlyGP_CY1, DATE_PY1, MonthlyGP_PY1, YOYGPDiff_M1, ...
WAYNE SHAW, NULL, NULL, NULL, NULL, NULL,

DATE_CY2, MonthlyGP_CY2, DATE_PY2, MonthlyGP_PY2, YOYGPDiff_M2, ...
10-01-2013, 2770.060000, 10-01-2012, NULL, -2770.060000,


Name, DATE_CY1, MonthlyGP_CY1, DATE_PY1, MonthlyGP_PY1, YOYGPDiff_M1, ...
SANDY LIN, NULL, NULL, NULL, NULL, NULL,

DATE_CY2, MonthlyGP_CY2, DATE_PY2, MonthlyGP_PY2, YOYGPDiff_M2, ...
10-01-2013, 29281.200000, 10-01-2012, 28025.810000, 1255.39,




The source table is structured thusly:


CREATE TABLE GPByMonth (
[SPRSNSLN] [VARCHAR](61) NOT NULL,
[M] [INT] NOT NULL,
[Y] [INT] NOT NULL,
[MonthlyGP] [Decimal] (14,6) NULL,
[MonthlyRev] [Decimal] (14,6) NULL
)

I'm not sure if this will help you but it sounds as if you need a calendar table (I used a CTE to get the needed months). I hope this gets you closer to what you need.

WITH CTE AS(
SELECT TOP 12 DATEADD( mm, (ROW_NUMBER() OVER(ORDER BY(SELECT NULL)) -1) * -1, DATEADD( mm, DATEDIFF( mm, 0, GETDATE()), 0)) period
FROM sys.all_columns
)
SELECT *
FROM CTE
LEFT
JOIN GPByMonth Cur ON Cur.M = MONTH( period) AND Cur.Y = YEAR( Period)
LEFT
JOIN GPByMonth Prev ON Prev.M = MONTH( period)
AND Prev.Y = YEAR( Period) - 1
AND Cur.SPRSNSLN = Prev.SPRSNSLN
ORDER BY Cur.SPRSNSLN , period DESC

Thank you for your help. I in fact do have a calendar table setup with code from: http://sqlserver2000.databases.aspfaq.com/why-should-i-consider-using-an-auxiliary-calendar-table.html

It comes in very handy.

I will see if I can apply it to this solution.



btw- did I use improper etiquette for my code post? I saw the link in your signature and thought I followed the standards; but maybe I missed something?

The DDL and sample data were helpful. You could use the IFCode tags to avoid having a very large post and keep formatting but that's just style.
I got lost on the expected results, but maybe that was just me. I might have get confused because I couldn't relate the title with the description.

Luis,
I spent some time and got this to look a little better and hopefully will clear up some of my post.

What I need is a table that gives one row for each salesperson with a set of columns for each month/year period.

I have a comma delimited example below. Rather than fill all twelve periods (some 48+ columns) I put in a [...] to indicate the rest of the columns. I also included code at the bottom to create the results table with no data in it.

I appreciate your time on this and will be better in the future with my post etiquette. :)

--Better Sample Results model:

CY = current year
PY = prior year

YOYGPDiff = Year Over Year Gross Profit Diff (CY - PY)

[names] [date per month CY] [Monthly GrossProfit CY] [date per month PY] [Monthly GrossProfit PY] [Monthly YOYGPDiff]

Name,DATE_CY1,MonthlyGP_CY1,DATE_PY1,MonthlyGP_PY1,YOYGPDiff_M1,DATE_CY2,MonthlyGP_CY2,DATE_PY2,MonthlyGP_PY2,YOYGPDiff_M2,[...],DATE_CY12,MonthlyGP_CY12,MonthlyGP_PY12,YOYGPDiff_M12

-- Better Sample data and table :
--===== If the test table already exists, drop it

I hope this will help you. You just need to complete the rest of the months with Copy-Paste-Replace.

),
Data AS(
SELECT period,
P.SPRSNSLN AS SPRSNSLN,
ISNULL( Cur.MonthlyGP, 0) MonthlyGP,
ISNULL( Cur.MonthlyRev, 0) MonthlyRev,
ISNULL( Cur.MonthlyGP, 0) - ISNULL( Prev.MonthlyGP, 0) AS MonthlyYOYGPDiff,
ROW_NUMBER() OVER( PARTITION BY P.SPRSNSLN ORDER BY period) MonthNo
FROM CTE
CROSS
JOIN (SELECT DISTINCT SPRSNSLN

SELECT SPRSNSLN,

If this data is for SSRS then you do not have to pivot in T-SQL as you can use a matrix to do the pivoting and simplify the query.


Far away is close at hand in the images of elsewhere.

Good point. Only this is just a small part of a much larger dataset that all has to be in the same matrix. Unfortunately, SSRS does not like to have more than one DataSet in a matrix without a bunch of hoops and gotchas; so I use Stored Procedures to do most of the heavy lifting and only return a small amount of rows. This keeps the report processing lean and mean.

The original dataset would be well over 153,000 rows over 100 columns if I let the matrices do all the walking. When I did that the report took over 45 minutes to process. Now, with this final piece I can whittle that monster dataset down to the 24 rows of salespeople and 60 columns. I have found that in SSRS if you have more than just about 40 records and 50-60 columns of data the report is too slow for live viewing; and has to be cached nightly; which will not work for the salespeople who must check the report multiple times per day to see where they are. Also, because we use Dynamics GP (another "brilliant" Microsoft invention) the data is so normalized that it takes no less than 3-4 complex joins just to get a list of what was sold and who sold it for any given point in time.

I know its a long reply, but I wanted to let you know I appreciate the thought and have actually gone down that rabbit hole with no success.

Cheers!
