Hi all, I know the pivot subject was discussed before but I have not found a proper solution to my needs. I have the following table : Date productID ProductName Products_Sold 2011-01-07 111 AAA 10 2011-01-07 222 BBB 20 2011-01-07 333 CCC 30 2011-01-14 111 AAA 15 2011-01-14 222 BBB 25 2011-01-21 222 BBB 35 2011-01-21 333 CCC 15 I want the query will return: productID ProductName 2011-01-07 2011-01-14 2011-01-21 111 AAA 10 15 0 222 BBB 20 25 35 333 CCC 30 0 15 I am using the following query to achieve that and it works perfectly - SELECT productID , ProductName max(case when date=( '2011-01-07') then Products_Sold else 0 end ) as date_2011_01_07, max(case when date =( '2011-01-14') then Products_Sold else 0 end ) as date_2011_01_14, max(case when date =( '2011-01-21') then Products_Sold else 0 end ) as date_2011_01_21 from TABLE group by 1,2 order by productID My special needs are: every week a set of products entering the table, 1. Is there a way to do this pivoting without changing the query every week? 2.Is there a way to define the columns names to be dates and not string? Thanks, Sami
