Re: Lost connection to MySQL server during query

[neil craig]

Hi Peter, thanks for the quick reply...

the quotes are just for safety as the query is generated dynamically...they don't cause a problem...

the tables are:

mysql> describe chatroom;
+---------------------------------+------------------+------+-----+---------+----------------+
| Field | Type | Null | Key | Default | Extra |
+---------------------------------+------------------+------+-----+---------+----------------+
| chatroom_id | int(63) unsigned | NO | PRI | NULL | auto_increment |
| lang_id | int(10) unsigned | NO | | 0 | |
| chatroom_label | varchar(255) | YES | | NULL | |
| chatroom_date_created_timestamp | int(32) unsigned | NO | | 0 | |
| chatroom_is_permanent_chatroom | tinyint(1) | NO | | 0 | |
| chatroom_date_deleted_timestamp | int(32) unsigned | YES | | NULL | |
| user_id | int(63) unsigned | NO | | 0 | |
+---------------------------------+------------------+------+-----+---------+----------------+

and

mysql> describe chatroom_allowed_user;
+----------------------------------------------+------------------+------+-----+---------+----------------+
| Field | Type | Null | Key | Default | Extra |
+----------------------------------------------+------------------+------+-----+---------+----------------+
| chatroom_allowed_user_id | int(63) unsigned | NO | PRI | NULL | auto_increment |
| chatroom_id | int(63) unsigned | NO | | 0 | |
| user_id | int(63) unsigned | NO | | 0 | |
| chatroom_allowed_user_date_deleted_timestamp | int(32) unsigned | YES | | NULL | |
+----------------------------------------------+------------------+------+-----+---------+----------------+

the query produces a valid result:

mysql> select distinct chatroom.chatroom_label as label, chatroom.chatroom_id as id from chatroom inner join chatroom_allowed_user using(chatroom_id) where chatroom.chatroom_date_deleted_timestamp is null and chatroom.chatroom_is_permanent_chatroom!="1" and (chatroom_allowed_user.user_id="1" or chatroom.user_id="1") order by chatroom_label asc;
+-------+----+
| label | id |
+-------+----+
| fwfwe | 29 |
+-------+----+

and i am running PHP5.1.4 as an apache2 module which were installed from dotdeb via apt...

is that enough info?

Thanks again
