Finding missing numbers in a sequence

Finding if a sequence has gaps is easy, finding the exact list of missing numbers is a little involved. The following query lists the missing numbers from a given auto-increment column.

```
SELECT a.id+1 AS start, MIN(b.id) - 1 AS end
FROM testtable AS a, testtable AS b
WHERE a.id < b.id
GROUP BY a.id
HAVING start < MIN(b.id)
```
