SELECT + COUNT zwraca tylko jeden wynik Opcje

[seba123]

Cześć! Mam następujący problem. Po dodaniu do zapytania SQL instrukcji COUNT serwer zwraca zawsze tylko jeden wynik. Bez wybierania zliczania rekordów wszystko jest ok. Oto moje zapytanie

[SQL] pobierz, plaintext 
SELECT 
			IF(votenum >= 1, votenum, 0) AS votenum,
			IF(votenum >= 1 AND votenum > 0, votetotal / votenum, 0) AS voteavg,
		 post.pagetext AS preview,
			thread.threadid, thread.title AS threadtitle, thread.forumid, pollid, open, postusername, postuserid, thread.iconid AS threadiconid,
			thread.dateline, notes, thread.visible, sticky, votetotal, thread.attach, thread.lastpost, thread.lastposter, thread.lastpostid, thread.replycount, IF(thread.views<=thread.replycount, thread.replycount+1, thread.views) AS views,
			thread.prefixid, thread.taglist, hiddencount, deletedcount
 
			, deletionlog.userid AS del_userid, deletionlog.username AS del_username, deletionlog.reason AS del_reason
 
			, threadredirect.expires
			, COUNT(zippy.userid) 
		FROM vb3_thread AS thread
			LEFT JOIN vb3_deletionlog AS deletionlog ON(thread.threadid = deletionlog.primaryid AND deletionlog.type = 'thread')
 
 
			LEFT JOIN vb3_post AS post ON(post.postid = thread.firstpostid)
 
			LEFT JOIN vb3_threadredirect AS threadredirect ON(thread.open = 10 AND thread.threadid = threadredirect.threadid)
			LEFT JOIN vb3_zippyclick AS zippy ON (zippy.threadid = thread.threadid)
		WHERE thread.threadid IN (0,46,45,44,43,41,40,39,38,37,31,30,26) 
		ORDER BY sticky DESC, lastpost DESC;
[SQL] pobierz, plaintext 

Gdzie leży problem ? Pozdrawiam.

EDIT: zapomniałem o pogrupowaniu. Czy

[SQL] pobierz, plaintext 
GROUP BY thread.threadid
[SQL] pobierz, plaintext 

będzie w pełni poprawnym grupowaniem ?
