Mnesia:select/4

Hi,

I want to use mnesia:select/4 to select a limited range of records.

The Guard looks like:

Guard = [{'>=','$8',NPT}],

I can always place a lower limit on the guard, but not an upper limit. So my thought of using select/4, with a number of results of 1 should work (i.e. it'll return the next highest match).

My worry is how efficient is it if it'll produce lots of continuation data?

The access methods are dirty.

Thanks

Matt
