The query being:
Create B as
(select sum (x), sum(y)
Where z between '1' and '3'
group by L, M, N
unique primary index on (L, M, N);
Table A has a unique primary index that is not involved with the query -- so there will be a full table scan. I do have a nupi on table
A on column M -- but I don't think that it comes into play (at least not according to the Explain).
