That query will/could bring a forum to it's knees running every page view.

Code:
mysql> explain Select * From thread order by rand() DESC LIMIT 1
    -> ;
+----+-------------+--------+------+---------------+------+---------+------+------+---------------------------------+
| id | select_type | table  | type | possible_keys | key  | key_len | ref  | rows | Extra                          |
+----+-------------+--------+------+---------------+------+---------+------+------+---------------------------------+
|  1 | SIMPLE      | thread | ALL  | NULL          | NULL | NULL    | NULL | 6026 | Using temporary; Using filesort |
+----+-------------+--------+------+---------------+------+---------+------+------+---------------------------------+
1 row in set (0.03 sec)
As you can see, a full table walk.

Here's a better way.

Code:
60*60 == 3600
3600*24 == 14400
14400*30 == 432000
1223479602 - 432000 == 1223047602

mysql> explain Select * From thread where dateline >= 1223047602 order by dateline DESC limit 1;
+----+-------------+--------+-------+---------------+----------+---------+------+------+-------------+
| id | select_type | table  | type  | possible_keys | key      | key_len | ref  | rows | Extra      |
+----+-------------+--------+-------+---------------+----------+---------+------+------+-------------+
|  1 | SIMPLE      | thread | range | dateline      | dateline | 4      | NULL |  104 | Using where |
+----+-------------+--------+-------+---------------+----------+---------+------+------+-------------+
1 row in set (0.00 sec)
See the difference? Gotta use those indexes. Rand() is bad.

It runs wrong.

When used, it transfers users to wrong thread. :(

Attention - this does not take care of hidden forums or forumpermissions, means it could also bring up a thread from your internal hidden administrator-forum...

noppid 10-08-2008 06:55 PM
Add "AND forumid not in(1,2,3)" to the query.

This hack needs a lot of work.
