Desperate for help with query using IN condition...

[Antivirus]

I'm trying to debug this alll day, if anyone can help i'll be very very happy.

My query is as follows:

PHP Code:

$sql = $db->query_read("
    SELECT * FROM " . TABLE_PREFIX . "task AS task
    WHERE 3 NOT IN (task.taskfilter)
    ORDER BY name ASC
"); 


In my table, i have several rows & values such as the following:
taskid name taskfilter
---------------------------------------------
1 foo 4,13,22
2 baa 5,3,101
3 moo 3
4 goo 1,56,87
and so on...

my problem is that I need my result from the query to contain only rows that DO NOT have the value 3 in the taskfilter column so I only want rows 1 and 4 to return.
problem is that row 1 is being excluded as well, since there's a 3 in the number 13. What am i missing here?
