Whats wrong with this query?

SELECT * FROM thread WHERE forum.forumid = 13 ORDER BY ID DESC LIMIT 10

I get this error:


Database error in vBulletin 3.0.6:

Invalid SQL:
SELECT * FROM thread WHERE forum.forumid = 13 ORDER BY ID DESC LIMIT 10

mysql error: Unknown table 'forum' in where clause

mysql error number: 1109

SELECT * FROM " . TABLE_PREFIX . "thread WHERE " . TABLE_PREFIX . "forum.forumid = 13 ORDER BY ID DESC LIMIT 10

Lol it is not the only prefix Zach :D He refers to the forum table in the where clause, but forum is not used in the FROM clause. Typical copy&paste&edit error.

SELECT * FROM " . TABLE_PREFIX . "thread WHERE forumid = 13 ORDER BY ID DESC LIMIT 10

Thanks :).
I don't have time to try this out, but it looks promising.\

Yep, so many idea's, so little time... If only I had time to handle every idea with the same time and care...

Ya goo' ol' pirate!

Still didn't work :(.

Query:


$getnewposts = $DB_site->query_first("SELECT * FROM " . TABLE_PREFIX . "thread WHERE forumid = 13 ORDER BY ID DESC LIMIT 10");

Error:

Invalid SQL: SELECT * FROM thread WHERE forumid = 13 ORDER BY ID DESC LIMIT 10
mysql error: Unknown column 'ID' in 'order clause'

mysql error number: 1054

Hmm ORDER BY threadid or forumid maybe?

Dont know what order you want.

I would say "ORDER BY dateline desc" ;)

But if you want the last posts prefer this one ;)

$getnewposts = $DB_site->query("SELECT p.* FROM " . TABLE_PREFIX . "post as p
LEFT JOIN " . TABLE_PREFIX . "thread as t ON (t.threadid = p.threadid)
WHERE t.forumid = 13 ORDER BY p.dateline DESC LIMIT 10");

Ok, now the DB error is gone.

But, with this code:

$getnewposts = $DB_site->query_first("SELECT * FROM " . TABLE_PREFIX . "thread WHERE forumid = 13 ORDER BY dateline desc LIMIT 10
");
$newposts = number_format($getnewposts['count']);

It just returns a "0", even though I'm absolutely sure there's a new post in the forum 13...

[Akex]

Ok I gave the request above as I saw you put LIMIT 10 and didn't put a coherent where clause.

What do you want exactly. A number of posts ?

$getnewposts = $DB_site->query_first("SELECT count(*) as count FROM " . TABLE_PREFIX . "post as p
LEFT JOIN " . TABLE_PREFIX . "thread as t ON (t.threadid = p.threadid)
WHERE t.forumid = 13 ORDER BY p.dateline DESC LIMIT 10");

It's better but, this request will give you the last 10 posts in forumid 13. You must give in the where clause a dateline condition. LIMIT 10 is useless unless you want to display at least 10 last posts and no more

WHERE t.forumid = 13 AND p.dateline > $bbuserinfo[lastvisit]

[Deaths]

Yes, I want the number of new posts (as a number) from a certain forum (13).

With that code $newposts returns 10, while there are no posts at all...

[Akex]

That what I said ;). How do you want number of newpost to be return has you didn't put any dateline condition in the query ?

Replace this in the query :

WHERE t.forumid = 13

By the last code I gave in post #11 ;)

[Deaths]

It works now, thanks!

Silly me, I forgot about the dateline condition ^^
