MySQL select
 

I'm using the vbulletin db classes.

I want to select field19 from users where users is member of group 15 and last activity was within 30 days.

Anybody know how to do this?

--------------- Added [DATE]1224909756[/DATE] at [TIME]1224909756[/TIME] ---------------

Got this far:

SELECT user.userid, userfield.field19
FROM user
INNER JOIN userfield ON user.userid = userfield.userid
WHERE (
user.membergroupids LIKE 15
OR user.usergroupid LIKE 15
)
AND userfield.field19 != '';

Just have to work out how to do the dates.

[sql]
select u.userid, uf.field19
from user u
join userfield uf using (userid)
where find_in_set('15',u.membergroupids) > 0
and to_days(now()) - to_days(from_unixtime(u.lastactivity)) <= 30
[/sql]
