SQL Last Weekday Statement

Attached below is my sql query that is working fine. I would like to add a WHERE clause to show

WHERE a.docdate = 'last weekday'

If today is Monday then I would want it to show all records where a.docdate='Friday'

Any ideas?

select a.sopnumbe, a.custname, a.cstponbr, a.docdate, a.user2ent, b.ponumber from 
(select * from sop10100 where docid = 'WARRANTY') A
left join
(select * from sop60100) B
on a.sopnumbe = b.sopnumbe
group by a.sopnumbe, a.custname, b.ponumber, a.docdate, a.cstponbr, a.user2ent

something like this? You just want it where the date is Friday?

select a.sopnumbe, a.custname, a.cstponbr, a.docdate, a.user2ent, b.ponumber from
(select * from sop10100 where docid = 'WARRANTY') A
left join
(select * from sop60100) B
on a.sopnumbe = b.sopnumbe
where datename(dw, a.docdate) = 'Friday'
group by a.sopnumbe, a.custname, b.ponumber, a.docdate, a.cstponbr, a.user2ent

Sorry...I was using Friday as an example. What I am looking for is the previous weekday. So, if today is Tuesday it would look for Monday's date. If today is Monday it would look for Friday's date.

Today is 06/24/08 and I would want a.docdate='06/23/08'

Monday was 06/23/08 so I would want a.docdate='06/20/08' (Friday)

OK...try this:

select a.sopnumbe, a.custname, a.cstponbr, a.docdate, a.user2ent, b.ponumber from
(select * from sop10100 where docid = 'WARRANTY') A
left join
(select * from sop60100) B
on a.sopnumbe = b.sopnumbe
where convert(varchar(10), a.docdate , 101) = convert(varchar(10), case when datename(dw, getdate()) = 'Monday' THEN DATEADD(d, -3, getdate()) else dateadd(d, -1, getdate()), 101)
group by a.sopnumbe, a.custname, b.ponumber, a.docdate, a.cstponbr, a.user2ent

I have check the () and they appear to be correct. Any ideas?

Thanks for both of your help. I gave Chapmandew 300 points because I used his solution but I feel like ScottPletcher actually had a more "defensive" solution by adding the if Sunday clause (even though I only thought about Monday). I appreciate both of your help!
