Creating a Stored Procedure that will summarize data in a table into a table reflecting period d

I am attempting to create a stored procedure that will launch at report runtime to summarize data in a table into a table that will reflect period data using an array type field. I know how to execute one line but I am not sure how to run the script so that it not only summarizes the data below but also creates and drops the table.

Any help would be greatly appreciated.

Current Table

Proj 1 | Task 1 | Cat 1 | 2007 | 01 | 40

Proj 1 | Task 1 | Cat 2 | 2007 | 02 | 20

Proj 1 | Task 1 | Cat 3 | 2007 | 03 | 35

Proj 1 | Task 1 | Cat 1 | 2008 | 01 | 40

Proj 1 | Task 1 | Cat 2 | 2008 | 02 | 40

Proj 1 | Task 1 | Cat 3 | 2008 | 03 | 40

Proposed Table

Proj 1 | Task 1 | Cat 1 | 40 | 0 | 0 | 2007

Proj 1 | Task 1 | Cat 2 | 0 | 20 | 0 | 2007

Proj 1 | Task 1 | Cat 3 | 0 | 0 | 35 | 2007

Proj 1 | Task 1 | Cat 1 | 40 | 0 | 0 | 2008

Proj 1 | Task 1 | Cat 2 | 0 | 40 | 0 | 2008

Proj 1 | Task 1 | Cat 3 | 0 | 0 | 40 | 2008

Thanks,

Check out the PIVOT operator

Mike, check out this sample script. You would need a case statement for each month, this is just using one for each month supplied in the example.

Code Snippet

CREATE TABLE #currentTable (

Project NVARCHAR(10),

Task NVARcHAR(10),

Category NVARcHAR(10),

FiscalYear INT,

FiscalMonth INT,

TotalHours INT

)

INSERT INTO #currentTable VALUES ('Proj 1', 'Task 1', 'Cat 1', 2007, 01, 40)

INSERT INTO #currentTable VALUES ('Proj 1', 'Task 1', 'Cat 2', 2007, 02, 20)

INSERT INTO #currentTable VALUES ('Proj 1', 'Task 1', 'Cat 3', 2007, 03, 35)

INSERT INTO #currentTable VALUES ('Proj 1', 'Task 1', 'Cat 1', 2008, 01, 40)

INSERT INTO #currentTable VALUES ('Proj 1', 'Task 1', 'Cat 2', 2008, 02, 40)

INSERT INTO #currentTable VALUES ('Proj 1', 'Task 1', 'Cat 3', 2008, 03, 40)

SELECT Project, Task, Category, FiscalYear,

SUM(CASE FiscalMonth WHEN 1 THEN TotalHours ELSE 0 END) AS '01',

SUM(CASE FiscalMonth WHEN 2 THEN TotalHours ELSE 0 END) AS '02',

SUM(CASE FiscalMonth WHEN 3 THEN TotalHours ELSE 0 END) AS '03'

FROM #currentTable

GROUP BY Project, FiscalYear, Task, Caetegory

DROP TABLE #currentTable

ShawnNSF,

When I run this statement the results in query analyzer it pulls back the results that I want to see on the bottom of the results pane based off of the the Selection statement looking into X_PJLABDIS(view).

My problem with this script is the INSERT step. It adds the values in the parantheses and I need it to add the values returned from the SELECT Statement below that.

Mike

CREATE TABLE PIVOT (

Project NVARCHAR(10),
pjt_entity NVARcHAR(10),
acct NVARcHAR(10),
Fiscalno_year INT,
Fiscalno_month INT,
total_hrs INT

)

INSERT INTO PIVOT VALUES ('Project', 'Pjt_entity', 'acct', 2007, 01, 40)

SELECT Project, pjt_entity, acct, Fiscalno_year,

SUM(CASE Fiscalno_month WHEN 1 THEN total_hrs ELSE 0 END) AS 'Month 01',
SUM(CASE Fiscalno_month WHEN 2 THEN total_hrs ELSE 0 END) AS 'Month 02',
SUM(CASE Fiscalno_month WHEN 3 THEN total_hrs ELSE 0 END) AS 'Month 03',
SUM(CASE Fiscalno_month WHEN 4 THEN total_hrs ELSE 0 END) AS 'Month 04',
SUM(CASE Fiscalno_month WHEN 5 THEN total_hrs ELSE 0 END) AS 'Month 05',
SUM(CASE Fiscalno_month WHEN 6 THEN total_hrs ELSE 0 END) AS 'Month 06',

SUM(CASE Fiscalno_month WHEN 10 THEN total_hrs ELSE 0 END) AS 'Month 10',
SUM(CASE Fiscalno_month WHEN 11 THEN total_hrs ELSE 0 END) AS 'Month 11',
SUM(CASE Fiscalno_month WHEN 12 THEN total_hrs ELSE 0 END) AS 'Month 12'

FROM X_PJLABDIS

GROUP BY Project, Fiscalno_year, pjt_entity, acct

Mike,

Those values are just for example. Do not use that part of the script. You seem to have gotten the idea by modifying the select statement (the part that was for you). I should have explained a little better that the other part of my snippet was just me building test data to show you the example query.

You can just run a query with the same idea as what I posted against the table you have with the data already populated in it.

Shawn,

As you can probably tell right now, I am have very limited knowledge of and using pivot tables and stored procedures. As you said I am going down the right path with this code.

How would I go about achieving returning the results into a report or table? Need all the help I can get right now and you are helping a lot and very much appreciate it.

Thanks,

Mike

FYI, using pivot with SS 2005
