Its been a while since I posted this. Would like to check again with the
folks on this list if they know why the results of query (b) are all
blank on MySQL 5.0.22. It works fine with 5.0.51a. If it is a bug in
5.0.22, can someone suggest a workaround for this (other than upgrading
MySQL).
Hi Nishi,
I think what's more relevant is why did you downgrade to 5.0.22? The
sorting issue you're experiencing was fixed for the 5.0.67 community
release. Many bugs will have been fixed between 5.0.22 and 5.0.51a;
downgrading is not a solution. Upgrade. If this is a new system you
CREATE TABLE t ( id TINYINT, title VARCHAR(10) );
INSERT INTO t (id, title) VALUES (1, 'aaa'), (2, 'bbb'), (3, 'ccc'), (4,
'ddd'), (5, 'eee');
(a) DO @sn := 0;
SELECT @sn:[EMAIL PROTECTED] sn, id, title FROM t GROUP BY id ORDER BY id desc;
| sn | id | title |
+--+--+---+
|1
Hi Nishi,
There was a bug in that version that affected the sort order when
combined with a group by statement
(http://bugs.mysql.com/bug.php?id=32202.) There are a couple of
workarounds but they are bad (e.g. removing primary key!)
I would strongly suggest you upgrade to 5.0.67 or
Looking further for more info on this issue reveals that there is a bug
in MySQL 5.0.51:
http://bugs.mysql.com/bug.php?id=32202
which got fixed in 5.0.52.
Thanks,
Nishi

Thanks for the response, Andy. I am now using the SELECT subquery to fix
that problem. However, when I run the following query (b) on 5.0.22, I
don't get any results - with and without the fix.
CREATE TABLE t ( id TINYINT, title VARCHAR(10) );
INSERT INTO t (id, title) VALUES (1, 'aaa'), (2,
