Thanks for the information.
I agree with what you say.
There is just one comment I'd like to make.
You are right that the TIMESTAMP has a specific range. I am comparing
it to a date outside that range. This could cause problems.
But I strongly believe that the SQL user, who in many cases
So, by using MacOS X, you are using a *nix based system.
Everything posted to this list is usually based in code (as in WebApps) or
by the MySQL command line. You need to learn how to use the command line

using and installing
Thanks a lot!! :D
You were right. There was a bug. Upgrading to mysql 4.1.20 solved my
problem.

Mark,
With the CHANGE clause of ALTER TABLE statement, you must provide the column
definition, so something like this is what you need:
ALTER TABLE actors CHANGE director_id actor_id MEDIUMINT UNSIGNED NOT NULL;
or whatever your original definition is.
AFAIK there is no way to rename a column
You can't just change the name without changing (or stating) the type.
ALTER TABLE actors CHANGE director_id actos_id varchar(96) default NULL;

You really should learn some of the command line items before delving into
the GUIs.
MySQL has the Administrator and Query Browser for MacOS X. If you need to
start with any GUI, these are probably the ones you should start with. It's
a nice blend of command line and GUI tools.

I think you are saying you want the Mode? if you are then the
following might work:
SELECT col2 as val, count(col2) AS cc
FROM my_table
GROUP BY val
ORDER BY cc DESC
LIMIT 1;
in your case this will retrun the value '2'
