RE: SQL newbie question

Have you looked at using union?  I'm not sure how it would handle uniqueness 
across queries though.  That may have to be done with joins.  Someone else may 
know a better way.

Subject: SQL newbie question


My fellow geeks:

Suppose I need to dump the results of several SQL SELECTs
into a uniquely keyed file. And since I'm endeavoring to
logically OR everything together, I don't give a rodent's
defecatory orifice about key collisions, other than
wanting them ignored, as quietly as possible.

SQL for Dummies mentions something about a MERGE
statement, without going into a lot of detail, and it
sounds tailor-made for the problem at hand, but I don't
see anything about any such thing in the V4R2 or V4R4 docs
(V4R2 being my usual reference, since it's the last
pre-InfoCenter reference, and V4R4 being the minimum
platform for the product).

On a related note, suppose I need to logically AND a
result set with a file, under similar circumstances. Or
logically AND NOT a result set with a file, again under
similar circumstances.

At any rate, everything would be executed under CLI.

Can anybody point me in the right direction?
