below will give you last wednesday


select dateadd(dd,datediff(dd,0,getdate())/7 * 7 + 2,0)

if you replace getdate with any date you will get previous wednesday from that date
ex.


select dateadd(dd,datediff(dd,0,'2011-11-14')/7 * 7 + 2,0)

This also works:


 Select datename(weekday, 2)
        ,dateadd(week, datediff(week, 2, getdate()) - 1, 2);

Change the '- 1' to any value to go back/forward that number of weeks.
