Hello,
I've got a table which containes two date colomns.
The first one is called `date` and the second `update`
In the first one I put the ticket creation date, and on update I add or

So the update colomn does not contain a value until the first update has
been done.

Hello I've tried the following with mysql 4.1.11
SELECT * FROM quick_contact WHERE (`status` = '0') OR (`status` = '2'
AND `update` '.(time()-864000).') CASE WHEN `update` = '' THEN ORDER
BY `date` DESC ELSE ORDER BY `update` DESC END CASE;
It does not work but, is it my code that is wrong
Can't you do Something like:
ORDER BY (update,date)
The major column of ordering would be update and the second date.
I'm not sure about this solution

I think that your solution will be sufficient for my needs, however I
would still like to know for my personal knowledge how to manage
correctly this kind of need.

+-+--++--+
| 5 | 40 | 90 | 100 |
| 2 | 10 | 60 | 70 |

I think the easiest is to create a new logical column with the correct
ordering, something like:
SELECT *, IF(update != '', update, date) AS o
FROM my_table ORDER BY o DESC;
I note that both 'update' and 'date' are reserved works :)
Also worth noting that this cannot be assigned an index
Thanks, it works like a charm :)

Hi,
I have a question regarding mysql master-slave replication's
Relay_Master_Log_File. I hope someone can answer me.
I have mysql setup to purge old logs that arent being used by master, and
also the max log size is set as 500MB. I see that new logs are created with
next number in order.

Richard,
No problem, glad it works. But note: this is not scalable. If you have
more than a few hundred rows, you may want to think about a better
solution, like storing the order field permanetly and giving it an index :)

Thanks,
This is for the unanswered list of questions, so the output list (not
the list stored in the mysql database) should never go over 100.
by scalable, do you mean alot of ressources being used or a long wait
for the answer? Because I belive I Could just use a simple limit if I

I searched for a few combination of words, and didnt reach anywhere. Thats

From this thread it looks like it never gets reset and keeps increasing the
numbering; I would still wish if it reset someday without affecting the
replication!

Not sure, but perhaps an even simpler method would be to consider the
initial insert an update as well... so the update column would always have
a value. Then the sort would (I believe) always be in the order you want,
and if you need to differentiate between rows that are new vs rows that

The query I gave you required the column 'o' to be calculated for each
row at the time of gathering the data. When all rows have been
gathered, the data will be stored and sorted in a temporary table. This
temporary table will be in memory or on disk depending on the setting of
