Howdy:
I need to put together an SQL statement that will return all of the
rows in table A that are not in table B. Table A and B have the same
primary key. For example:
select count(a.*)
from a (nolock) left outer join
b (nolock) on a.id = b.id
where a.id != b.id
This did not work. It returned 0 rows. I know that this could be
done very easily in a sub-select, but that seems inefficient. Is
there any way to accomplish what I mentioned above in the join
statement or is the sub-select the way to go?
Thanks for the help,
Tom
