Sorry to so called hijack the thread but this may also be useful for jroy.

What's the difference between using just query and query_first?

query() returns a handle that you can reference using fetch_row() to fetch sequential rows. query_first() just returns the first row, if any, of the query.

These two are equivalent:

PHP Code:


		
			
$foo = $DB_site->query_first("SELECT COUNT(*) FROM " . TABLE_PREFIX . "post");

and

PHP Code:


		
			
$result = $DB_site->query("SELECT COUNT(*) FROM " . TABLE_PREFIX . "post");

$foo = $DB_site->fetch_array($result);

(BTW, SELECT COUNT(*) is fine if there is no WHERE clause, at least in MySQL's case)
