Need help converting Oracle PIVOT script to SQL Server

Question

I hope it is not inappropriate to ask for SQL Server question in a .NET forum. I can not understand SQl 2k5+ syntax for pivoting. I am pivoting on company name and storenbr in the following. Thanks for any help.
WITH dummydata AS
  SELECT       'Store1'  AS storenbr, 2 AS period, 1 AS weeknbr,   '40' AS PLU, 'tomato'  as descrip, 16  AS used, 100 AS wasted from dual UNION ALL

Answer 1

ArthurZ thank you, it was just a minor bug:
(DT_DATE)(SUBSTRING("20001211", 1,4) + "-" + SUBSTRING("20001211",
5,2) + "-" + SUBSTRING("20001211",
7,2) )
Working fine now :) thanks!
Sorry if I caused it, but glad you found it
Arthur
