Re: SQL - find 'missing' numbers

Chuck, you are amazing! That is exactly what I need. Now I can expand upon this technique to get the desired results (the original example was oversimplified). Plus I have a new 'tool' for future use.

Thank you very much.

I can not test, but the following use of EXCEPT I think should suffice:

with
in_seq (seq_nbr) as
( values(1)
union all
select seq_nbr+1
from in_seq
where seq_nbr<999
)
(select seq_nbr
from in_seq
except
select the_numeric_col
from the_file
) order by 1
