Question : Pivot Table with dynamic column headers

Hi all,

I'm trying to pivot some data in a T-SQL query, so it doesnt have to be done manually in Excel.  Just wondering if it was possible, and if so, how.

Basically 2 sections to the question, 1. Have the column names (product and date) be dynamic.  2. Have 2 column headers, showing each date, and all products that fall under that date.

Please see attached code section for sample table and desired output.

Hopefully this is clear, but if anymore info is required just ask.

Thanks,
Al
