same table query...

same table query...

same table query...

(OP)
Hi,
I'm trying to compare 2 sets of data from the same table.
for example
status Recd# Date
COM    1000  08/20/2008
COM    1001  08/20/2008
AVL    1002  08/20/2008
AVL    1000  08/20/2008
AVL    1001  08/20/2008

The result i'm looking for is records with AVL status that are not in COM status. in this case
AVL    1002  08/20/2008

I tried to do subqueries but it did not work at all
something like
select recd# from table
where date = today and status = "AVL" and recd# NOT IN (Select recd# from table where Status= "COM" and date = today)
but return 0 records...

I'll appreciate any help.

thanks!
