Here are the requests I am doing :
$tab1 = $this->Task->findAll('user_id = ' . $user_id . ' AND duedate =
"' . date('Y-m-d') . '"', null, 'duedate ASC');
$tab2 = $this->Task->findAll('alternate_id = ' . $user_id . ' AND
user_id != '.$user_id.' AND duedate = "' . date('Y-m-d') . '"', null,
'duedate ASC');
$tasks = array_merge($tab1, $tab2);
$this->set('tasks', $tasks);
I don't like that way, because I am using twice /findAll()/ on the same
table and for only one result at the end.
That's why I was wondering if there is a way to do it better.
I think that your example is better than mine because you are doing a
simple query ($tmp) to get the ids (this query should not take too long)
and then the /findAll()/ query.
I don't like my way because, by using twice /findAll()/, my requests
could take too long for a lot of rows... And I don't see how to rewrite
it without using UNION because there is the condition user_id !=
'.$user_id.' in the 2nd one which is the contrary of 'user_id = ' .
$user_id . ' in the first one...
Anyway, thanks for you help !
