Is the plus query return more then 50% of the records? If so, MySQL
won't return anything since the result set isn't that relevant.

There are only 500 records in total of which three are relevant to the
'plus' query.
But there is only 1 relevant result from the 'real' query, and that did
return a result.

Can anyone tell me why this query for the word 'plus':
mysql SELECT *
- FROM booktitles
- WHERE MATCH (category , publisher , bookTitle , author)
- AGAINST (CONVERT( _utf8'plus'USING latin1 )
- IN

Hi all
I can't work out why this query is also updating a TIMESTAMP col?
UPDATE news SET title = 'new title', text = 'new text' WHERE id = '4'
The table is very simple:
* id INT
* date TIMESTAMP // this is current date when 'updating'?
*

UPDATE news SET title = 'new title', text = 'new text' WHERE id = '4'

Because, according to TFM; (http://www.mysql.com/doc/D/A/DATETIME.html)
Automatic updating of the first TIMESTAMP column occurs under any of
-BEGIN PGP SIGNED MESSAGE-

other column changes value. (Note that an UPDATE that sets a column to the
value it already has will not cause the TIMESTAMP column to be updated,
because if you set a column to its current value, MySQL

It's a paticular feature of TIMESTAMP column. Read the manual:

NW UPDATE news SET title = 'new title', text = 'new text'
Summary
If I have a filed of type DATETIME in a table and do a query with an order
on that field than records with a datetime in the afternoon are returned
before articles in the morning.
EG:
mysql select pubtime,articleid,headline from articles where articleid
mysql 3050 order by pubtime;
3076 is 2:53 in the morning, not the afternoon.
