query code standards

[Antivirus]

I'm aware that both give me the same result, however with regards to an interger in a WHERE clause, which method is better? Enclosing the int within '2' or without. Is either method faster, or less likely to create problems elsewhere?

PHP Code:

$check = $db->query_first("
    SELECT eventid FROM " . TABLE_PREFIX . "scst_event 
    WHERE eventid = '" . $vbulletin->GPC['eventid'] . "' 
    AND userid = '" . $vbulletin->userinfo['userid'] . "' LIMIT 0, 1
"); 


or like this:

PHP Code:

$check = $db->query_first("
    SELECT eventid FROM " . TABLE_PREFIX . "scst_event 
    WHERE eventid = " . $vbulletin->GPC['eventid'] . " 
    AND userid = " . $vbulletin->userinfo['userid'] . " LIMIT 0, 1
"); 


thanks

I've always been told that integers shouldn't be quoted.

Yep, its more efficient to not quote integers as PHP will view them as a string and will thus be forced to do a conversion before searching for it in an int field.

ah, i see - that makes sense, thanks for clarifying it.

Quite often, in native vb code, i have seen something like '" . $vbulletin->userinfo['userid'] . "' so I was confused as to why. Thanks
