what are the 1700 values

if the are all alphabetic and not too long you could do something like the below though it's all getting a bit long-winded

select
chr(65+(floor((rownum-1)/676)))||chr(65+(floor((mod(rownum-1,676))/26)))||ch r(65+(mod(rownum-1,26)))
from addresses -- any table big enough
where rownum < 26*26*26
group by
chr(65+(floor((rownum-1)/676)))||chr(65+(floor((mod(rownum-1,676))/26)))||ch r(65+(mod(rownum-1,26)))
having
chr(65+(floor((rownum-1)/676)))||chr(65+(floor((mod(rownum-1,676))/26)))||ch r(65+(mod(rownum-1,26))) in

('ABA','ACY','ABT'...) -- the 1700 values minus
select code
from table

Good morning list,

Environment HP-UX 11.0 Oracle 8.1.6

Can anyone help with this SQL.

I can get a result set of values from a table that match a given list of values -

select code
from table
where code in ('A','B','C','D','E')

I can get a result set of values from a table that do not match a given list of values -

select code
from table
where code not in ('A','B','C','D','E')

So far so good.

Now, how do I get the set of values from the list that do NOT have a matching value in the table?

I cannot create any objects in the schema I am working in otherwise I would create a table with the values and do a minus, but I can't figure out how to do it in SQL only.

Thanks in advance, folks.

Steve
