Code:
+----+-------------+--------------------+-------+---------------+------+---------+------------------------------+------+------------------------------+
| id | select_type | table | type | possible_keys | key | key_len | ref | rows | Extra |
+----+-------------+--------------------+-------+---------------+------+---------+------------------------------+------+------------------------------+
| 1 | SIMPLE | pac2_notifications | range | what | what | 919 | NULL | 2 | Using where; Using temporary |
| 1 | SIMPLE | pac2_titles | ref | uri | uri | 767 | test.pac2_notifications.what | 1 | |
+----+-------------+--------------------+-------+---------------+------+---------+------------------------------+------+------------------------------+
2 rows in set (0.00 sec)
I know the when "using temporary" shows up - it's not good ...
Any help would be appreciated!
