mysql query involving dateline

[chris1979]

I want to change the title of all new threads that were posted in a certain forum in the last 30 days.

Can you help me with the query?

I think it should be something like...

UPDATE thread SET title='additional text '+title
WHERE dateline<????
AND forumid=1;

Thanks in advance!

You can use a timestamp generator (http://www.4webhelp.net/us/timestamp.php) to get the variable you need. If you're doing this in PHP, you can use the following...

$last30 = mktime(0, 0, 0, date("m"), date("d")-30, date("y"));

Then simply plug $last30 into your SQL statement.

thanks

this bit will work?

title='additional text '+title

if you are trying to append an existing variable to a new variable in PHP you use the following format

<?
$var1 = "some text here". $var2
?>

Yes, that should work. However, always try on some test data first!

I've never tried with a Plus Symbol before, but the way that I would do it is:
UPDATE blah SET bleh=CONCAT('blah blah blah ', bleh);
