This would return sequence values with "gaps after":

SELECT seqval FROM mydata a
where not exists
(select * from mydata b where a.seqval+1 = b.seqval)
ORDER BY seqval

Subject: Looking for gaps in a key sequence

Given a key sequence in a file, really just a series of numbers, does
anybody know of an algorithm, other than brute force, for finding gaps
in the sequence?
