vb.org Archive - Forum Home Enhancements - Cyb

For big forum at one point it runs an absolutely strupid query, that blocks forum loading. In my case the query left joined tread and user on username and lastposter respectively, wich caused mysql to do " Copying to tmp table " on and on. Here is an example of such a query:

Code:

SELECT thread.forumid, thread.threadid, thread.title, thread.lastpost, thread.lastpostid, thread.lastposter, thread.iconid, user.userid

FROM vb_thread AS thread

LEFT JOIN vb_user AS user ON ( user.username = thread.lastposter )

WHERE threadid >0

AND visible =1

AND OPEN !=10

AND forumid
