Question

I need to create a report using SQL Server 2008R2 Stored procedure that will return the following shape of data:

My view in SQL Server is returning data like this:

The user will select start_date and end_date and that date range will be displayed in columns, i.e. if user selects Apr 1,2012 to Apr 7, 2012 then 7 days, Day1 to Day7 will be shown in columns. The left column will show the totals of “ApplicationId” field.
Note that “Assigned”, “Processing”,.. are Status field.

Answer 1

Check this example.. as like i have implemented using this one. you can create your dynamic columns/ dynamic pivot. but you have to it using execute in sql server.

You can implement/ modify your query as you want.

Ref: Pivots with Dynamic Columns in SQL Server 2005

DECLARE @query NVARCHAR(4000) SET @query = N'SELECT tID, '+ @cols +' FROM (SELECT  t2.tID
      , t1.ColName
      , t2.Txt FROM    Table1 AS t1
        JOIN Table2 AS t2 ON t1.ColId = t2.ColID) p PIVOT ( MAX([Txt]) FOR ColName IN ( '+ @cols +' ) ) AS pvt ORDER BY tID;'

Executing this with

EXECUTE(@query)

For more reference about this:

Hope this help..
