I need to generate report which shows number of orders for each ProductID for each week in year 2013. Ideally would be to generate 54 weeks as pivot table so week1, week2 would be columns and 3 rows for 3 products and order count for each product each week.

You're welcome. Thanks loads for posting a sample data script - it doesn't half make a difference

Can you show what you mean by this, using a script?

Hi

Exactly same tables and data. But instead of having 'week1', 'week2' etc as columns I would like to have dates for example '01.04.2013', '02.04.2013', etc. I need to be able selected date range so If I select between 01.04.2013 to 30.04.2013 I will have 30 columns starting with column '01.04.2013' and finishing with '30.04.2013'. I need same output but instead of weekly report I need daily report within date range.
