changing parameter in SQL query from Excel
 

I am using Excel 2007 and bring data into Excel via an SQL query. How can I
change parameters in the 'Where' clause in Excel without going into the
Connection properties in Excel and changing the parameters in the sql querie
itself?
In the example below I would want to change the DateKey:
SELECT salles
FROM dbo.SalesFact
WHERE (DateKey = 20080524) AND (DateKey <= 20080929)
Thanks
