val,
Surely this would only be possible if "SIZE1" and "P2" [sic - maybe "SIZE2"] were
constants, ie that all small
packs had SIZE="small" and all large packs were defined as SIZE="large".
(also that all products had no more than two sizes)
Interesting thought though (subject to the <=2 sizes constraint), could there be a
LEFT JOIN off PRODUCTS, but
put P1 and P2 into a cartesian product but only selecting where there is inequality:
WHERE P.NUM=P1.ID AND P.NUM=P2.ID
AND P1.SIZE <> P2.SIZE
[sorry, machine is busy on something, so haven't prototyped it]
Raymond: is there a SIZE (type of) field? Do the above constraints apply? What are the
table definitions you are
using? Any chance of some sample data?
Please advise,
