I actually need the username, email, usertitle and location of users who joined on a particular date and from a particular location. If I could get the output of the query downloaded to an excel file, that will be cool.

How do I do it? The data I'm looking for is actually in multiple tables. So I need help with SQL queries using "join" of multiple tables.

Any help? Thanks in advance.

[sql]
select u.username, u.email, u.usertitle, f.field2
from user u
join userfield f
using (userid)
where f.field2='whatever location it is you are interested in'
and date(from_unixtime(joindate)) = 'whatever date you want in YYYY-MM-DD format (eg 2006-04-04)'
[/sql]
