Hello Romano!

DB-SELECT only gives you the row-ids; getting all the records in a
block is not possible with dbms.r, as I've never had a need for
that; to get them as a block of objects, you can use:
block: make block! 1024
db-foreach row %table/ none [
insert tail block make row []
]
The MAKE is needed because DB-FOREACH reuses the same object
across evaluations for efficiency.

I was thinking about b-trees... but hash! is certainly an option.

Gabriele.
