Grouping Data with Weekly break out?

Hi All,
I'm trying to figure out and learn how to do the following:
/*I have the following query which works:*/
SELECT DataSource AS [Service Line], NamePrep AS [PO Created By],
COUNT(PoNumber) AS [Total Of PONumber]
FROM OPW
WHERE (ReqSubmitDate BETWEEN '03/ 01/2005' AND '03/31/2005')
GROUP BY DataSource, NamePrep
My question here is how can I get a wly breakout of the COUNT(PoNumber)?
I want a column for each w and the number of PONumbers Per Datasource and
NamePrep for that w.
Example Output:
Service Line | PO Created By | Total Of PONumber | 3/5/2005 |
3/12/2005 | ETC...
MNS JOHN 10
MNS ERIC 25
FMS CARL 8
Hope my question makes sense :)
John.If you had a calendar table, this would be easier, but if not, you need to
know the columns you want, or use dynamic SQL...
Select DataSource AS [Service Line], NamePrep AS [PO Created By],
COUNT(PoNumber) AS [Total Of PONumber],
Sum(Case When ReqSubmitDate
Between '03/ 01/2005' AND '03/8/2005' Then 1 End) Wk1Count,
Sum(Case When ReqSubmitDate
Between '03/ 09/2005' AND '03/16/2005' Then 1 End) Wk2Count,
Sum(Case When ReqSubmitDate
Between '03/ 17/2005' AND '03/24/2005' Then 1 End) Wk3Count,
Sum(Case When ReqSubmitDate
Between '03/ 25/2005' AND '03/31/2005' Then 1 End) Wk4Count
FROM OPW
WHERE (ReqSubmitDate BETWEEN '03/ 01/2005' AND '03/31/2005')
GROUP BY DataSource, NamePrep
If you want it dynamic, you have to write code to dynamic construct an SQL
statement like the one above, based on the date ranges you pass it, and then
execute that SQL Statement using EXECUTE, or sp_ExecuteSQL() functions
