Why the insistance on "at once"?
Do you mean in a single SQL statement,
or a single line of code? How many dimensions?
For 2 dimensions it is certainly possible with
a single line of code and multiple invocations
of a SQL statement (
for).
If this is not data you are intending to query by
(and off hand I don't see how you intend to,
RDBMS are not meant for this, or at least for
what I am interpreing your vague description as),
you could use some form of
serialization
and store the result as a BLOB.
