Error .. 1054 MYSQL .. Where Clause seems correct .. ideas?
 
This is a simple statement to draw some info on a home page regarding user stats .. right now the error i get is
Quote:
Invalid SQL:
SELECT userid, username FROM myprefix_user WHERE myprefix_userid=2;

MySQL Error : Unknown column 'myprefix_userid' in 'where clause'
Error Number : 1054
I changed the prefix in this example, but the correct prefix is in the error. What exactly is it complaining about?

Code:
// forum stats start 
$numbersmembers = $db->query_first("SELECT COUNT(*) AS users,MAX(userid) AS max FROM " . TABLE_PREFIX . "user"); 
$numbermembers = number_format($numbersmembers['users']); 
$counter = $db->query_first("SELECT COUNT(postid) AS posts, COUNT(threadid) AS threads FROM " . TABLE_PREFIX . "post");
$totalposts=number_format($counter['posts']); 
$countthreads = $db->query_first("SELECT COUNT(*) AS threads FROM " . TABLE_PREFIX . "thread");
$totalthreads=number_format($countthreads['threads']); 
// forum stats end 

// total online start 
$datecut = TIMENOW - $vbulletin->options['cookietimeout']; 
$headerguests=$db->query_first("SELECT COUNT(*) AS count FROM " . TABLE_PREFIX . "session WHERE userid=0 AND lastactivity>$datecut"); 
$headerusers=$db->query_first("SELECT COUNT(DISTINCT(userid)) AS count FROM " . TABLE_PREFIX . "session WHERE " . TABLE_PREFIX . "session.userid>0 AND " . TABLE_PREFIX . "session.lastactivity>$datecut"); 
$headerguests=$headerguests[count]; 
$headerusers=$headerusers[count]; 
$totalonline=$headerguests+$headerusers; 
// total online end

// get newest member name and userid start 
$getnewestmember=$db->query_first("SELECT userid, username FROM " . TABLE_PREFIX . "user WHERE " . TABLE_PREFIX . "userid=$numbersmembers[max]"); 
$newusername = $getnewestmember['username']; 
$newuserid = $getnewestmember['userid']; 
// get newest member name and userid end

ive seen the page before i was more hoping for somone to point out the error if it jumped out at them ..

I see the section you are pointing out, but how can i also set that syntax in this code.

cause it seems the problem is at this section

Code:
$headerguests=$db->query_first("SELECT COUNT(*) AS count FROM " . TABLE_PREFIX . "session WHERE userid=0 AND lastactivity>$datecut");

This is the same error as this thread ;

https://vborg.vbsupport.ru/showthread.php?t=119719

The broken line is this one ;

PHP Code:
$getnewestmember=$db->query_first("SELECT userid, username FROM " . TABLE_PREFIX . "user WHERE " . TABLE_PREFIX . "userid=$numbersmembers[max]"); 
The table name is missing from the WHERE section after the table prefix.

i.e. TABLE_PREFIX . "userid should be TABLE_PREFIX . "user.userid

However, table prefix should not be used in WHERE clauses anyway, instead you should us an AS after the initial table selection, like this ;

PHP Code:
$getnewestmember=$db->query_first("SELECT userid, username FROM " . TABLE_PREFIX . "user AS user WHERE user.userid=$numbersmembers[max]"); 
Finally, since only one table is actually used in this select, the table references can be dropped completely as no ambiguity is possible.

PHP Code:
$getnewestmember=$db->query_first("SELECT userid, username FROM " . TABLE_PREFIX . "user WHERE userid=$numbersmembers[max]");
