Maybe a SHOW CREATE TABLE `tasks`\g could shed some light.
I can't figure out how to get puTTY to log the session so I can't
cut and paste the output, but here is a phpMySQL export of the
table with the extra stuff typed in from the create table
task_id mediumint(9) NOT NULL AUTO_INCREMENT

due_date_time', 'task_id')
UNIQUE KEY 'requestor' ('requestor', prirority','due_date_time',

As a workaround I changed status to task_status and now it
works just fine.

RE: Update Doesn't Update!
If ID column is primary key and auto increment as you said, it cant be equal
to zero.
You got a query which reads:
UPDATE columns WHERE false
There is no chance for any updates.

Look at the message, 0 rows changed and 1 warning.
You cannot have ID=0 if ID is an index.
You can, but not if it's an auto-increment field.
Also, not *entirely* correct, although you have to jump through a few hoops:
it can occur if the field was changed to auto_increment *after* the 0 was
put in there.
Yes, I inherited a database like that once, and yes, it fucks up your day.

I'm lost. I set up this database originally with auto_increment and the
first value was 0. I thought that was always the case. Is there a problem
here?

I thought that was always the case. Is there a problem here? Yes, that should not have happened. For autoincrement fields, both NULL and 0 are magic values to get the next number from the sequence at insert time.

Re: UPDATE doesn't work
Hi mysql SELECT prezzo, totale FROM ordini WHERE numordine=1157; mysql UPDATE ordini SET prezzo = prezzo/1.024, totale = totale/1.024 WHERE numordine1385 AND dataord'2003-06-01'; You are selecting data for numordine = 1157, but are updating all records that have numordine 1385. 1157 1385.
