need to go back in time.

Jerry,
Here is a workaround for 4.1.22:
SELECT
a.id+1 AS 'Missing From',
MIN(b.id) - 1 AS 'To'
FROM tbl AS a, tbl AS b

Jerry,
Here is a workaround for 4.1.22:
SELECT
a.id+1 AS 'Missing From',
MIN(b.id) - 1 AS 'To'
FROM tbl AS a, tbl AS b
WHERE a.id b.id
GROUP BY a.id
HAVING `Missing From` MIN
Thanks.
Although I've been around SQL for quite a while, I've never really gotten
the hang of self-joins.

Well, 5.x accepted the query. It's been running for awhile, now, so I'll

Looks like a 4.1.22 bug.

Yes, that would have been a very good idea. I did not design this.
Even if we used auto-increment, my current problem would be the same:
finding gaps in the numbering.

Hi all,
I'm just throwing something out ...
How about:
select a.id,b.id from dataset a left join dataset b
on a.id=b.id+1
where b.id is null;
This should find single gaps. It won't find larger gaps.
Just my $.02.

Why do they need to be sequential? When this requirement comes up it's
usually for illogical reasons.
