If my last post read (and I see that it did) that I was defending myself
as opposed to falling ALL OVER my sword, I apologize: allow me to be clear:
No, you're all correct and M. Sokolewicz doubly so: I had
unintentionally selected fields from the wrong table for no reason other
than lack of sleep coupled with lack of experience and a desperation to
try to understand
The problem was that I was pulling data in a manner both useless and
complex from a thoroughly unnecessary table (I could tell you all why
but you'll all just laugh at me more)
I am grateful for all the help everyone has offered up to now and hope I
did not offend - I was trying in my last post to indicate that I was
an idiot, and it appears I've come off as arrogant. I promise it was not
my intent!

Thanks for all the replies. Jochem, thank you for this code, which
will take me all night to understand (though I bet it works). I also
note that SELECT DISTINCT worked here, too
Also as many of you noticed before me, the art_id was in there as a
fly in the ointment.
by that statement I ment the exact same thing Jochem ment in his 2nd
part; I have NO idea why you're selecting *ANYTHING* from the arts
table... it's *useless* if you don't need the data...
Er, yes, that was what I meant: I had unintentionally included that
bit.Thank you for your help.
Er, Jack - your original query was:
SELECT art.art_id,art.publisher_id,publisher.publisher_name,
FROM art
LEFT JOIN publisher
ON publisher.publisher_id=art.publisher_id
which is a selection on the art table... ( with a typo)
if you did:
SELECT art.publisher_id,publisher.publisher_name
FROM art
LEFT JOIN publisher
ON publisher.publisher_id=art.publisher_id
nothing would change. and if you did:
SELECT publisher.publisher_id,publisher.publisher_name
publisher
i.e. not 'unintentionally' selecting from the arts table.
then you would not have had a problem in the first place?!
I think I'm missing something ;-)
