Re: SQL join question

[rick baird <rick.baird@xxxxxxxxx>]

never mind, got it!

for the record:

select KEY1, DESC1, KEY2, DESC2
from FILE1
left outer join FILE2
on KEY1 = KEY2
UNION
select KEY1, DESC1, KEY2, DESC2
from FILE2
exception join FILE1
on KEY1 = KEY2
order by KEY1, KEY2

thanks for letting me use this forum jar the cobwebs loose from my own brain!
