Comment:
This doesn't look to be a bug in Django. This is a more of MySQL query
parser bug.
Query generated by Django ORM
{{{
UPDATE `CoreApp_room` SET `name` = 'suite'
WHERE `CoreApp_room`.`house_id` IN
( SELECT U0.`id` FROM `CoreApp_house` U0
INNER JOIN `CoreApp_room` U1
ON (U0.`id` = U1.`house_id`)
WHERE U1.`name` LIKE '%suite%'
)
}}}
As we can the query generated by Django is totally valid but MySQL server
has raise error
