[development] programming question (drupal specific)

[VJ Rao]

Whats the difference between these two code snippets (1 works, 2 doesnt) :

1)

$nresult = db_query('SELECT n.nid, n.body, n.type, n.title, n.promote,
n.moderate, n.teaser, n.created, n.changed, u.name FROM {node} n ,
{users} u, {term_node} tn, {users_roles} ur  where  n.uid = u.uid AND
n.nid=tn.nid AND u.uid=ur.uid AND n.status = 1 AND n.created > %d
ORDER BY n.created', $period);

   $nodes = array();

   while ($node = db_fetch_object($nresult)) {
     $nodes[$node->nid] = $node;
   }

2)

$nresult = mysql_query('SELECT n.nid, n.body, n.type, n.title,
n.promote, n.moderate, n.teaser, n.created, n.changed, u.name FROM
node n , users u,term_node tn, users_roles ur  where  n.uid = u.uid
AND  n.nid=tn.nid AND u.uid=ur.uid AND n.status = 1 AND n.created >
$period ORDER BY n.created');

$nodes = array();

while ($row = mysql_fetch_array($nresult, MYSQL_NUM))
{
 $nodes[$node->nid] = $node;

}

Regads,
