SQL Query - Cutt off text

[N8]

I am Running Logician's WebTemplates, and I can't figure out how to edit this Query so that it only grabs the first 200 characters from p.pagetext

Does anyone know how this can be done?



[sql]
SELECT t.threadid, t.title, t.firstpostid, t.lastpost, t.replycount, t.postusername, t.postuserid, t.lastposter, t.dateline, t.views, p.pagetext
FROM " . TABLE_PREFIX . "thread t
LEFT JOIN " . TABLE_PREFIX . "post p ON p.postid = t.firstpostid
WHERE t.forumid = '146'
AND t.open = '1'
AND t.visible = '1'
ORDER BY t.dateline DESC
LIMIT 0 , 15
[/sql]
