[xquery-talk] outer join between 2 sequences

[Ihe Onwuka]

I have sequence A consisting of the numbers 0 to 4000000 and sequnce B
consisting of about 100k random I numbers within the range of sequence A
and I want the outer join where sequence B is "null".

Should one expect bad performance in sequence B is not sorted and can one
expect reasonable performance if it is?

I am guessing that performance will vary by implemetation.
