You can use the NOT EXISTS statement. It will be something like:

select * from a
where not exists (select * from B where A.keycolumn = B.keycolumn)

or you could use a temp table approach ...

select * into #a from tableA

delete #a
from #a, tableB
where #a.keyCol1 = tableB.keyCol2
and #a.keyCol2 = tableB.keyCol2 .....

select * from #a

this would give u the desired result set..

cheers !!!
