USE test;
DROP TABLE IF EXISTS event;

INSERT INTO event (timestamp) VALUES

Could you expand a little on how that works?
I am starting to think that I wont be able to get the results I need
without post processing.
Looking at the results:

Ugh. My perl isn't quite right there. Here's a bit better (e.g.
working) example:
If you create the table, then put this in "populate_hours.pl":
BEGIN
#!/usr/bin/perl
$counter = 0;
while ($counter < 100) {
print "INSERT INTO all_hours (date_hour) VALUES (
DATE_ADD('2000-01-01 00:00:00'
One of the most puzzling and challenging things to do with SQL can be
to show what's NOT there, as you're trying to do.
Many people opt to do such a report in their favorite scripting
language for this reason, as one can easily increment timestamps by a
given amount and re-do the query. Can be r
That query doesn't return empty values. Just to clarify what I want as
the result:
My initial query was this,
mysql> select count(*),DATE_FORMAT(timestamp,'%H') AS hour FROM event
WHERE timestamp between '2007-01-10 04:00:00' and '2007-01-11
04:00:00' AND sid=1 GROUP BY hour;
+--+--+
You can't join on the result of calculations in the field selection. The result is not associated with any table. So the problem
isn't so much with the date_format statement, but that you are joining on HOURS.hour the timestamp, not HOURS.hour the DATE_FORMAT.
I would think you would be getting a
Your explain plan should not change based on the client you are using. The
explain plan is the path for the query not the return of data to the client.
Are you using sockets when connecting locally on the Free-BSD machine?
Sockets are normally faster than using the tcp/ip port.
