Hi,

You can achieve this by using Pivot. See the below example. You might be get the idea.

after lots of querying i got query that i want this query displays the output in cross tab format dynamically

consider i have table named SalesRepor having fields Month,Branch,Sales

SQL

declare @columns varchar(max)
declare @convert varchar(max)
select   @columns = stuff (( select distinct'],[' +  Month
                    from SalesReport
                  
                    for xml path('')), 1, 2, '') + ']'


set @convert =
'select * from (select Month,Branch,Sales from SalesReport) SalesRpt
    pivot(sum(Sales) for Month
    in ('+@columns+')) as pivottable'


execute (@convert)

This operation is called matrix transposition in algebra. Since you specified only SQL-Server in the tags, I looked on google T-SQL solutions, but there are many approaches:
