is it correct code ? exceed memory limit :(

[roxxx]

require("global.php");
$getposts = $db->query_read("
SELECT post.postid AS postid, post.pagetext AS pagetext
FROM " . TABLE_PREFIX . "post AS post
WHERE postid='1111';");
$post = $db->fetch_array($getposts);
echo "<b>".$post['postid']."</b> - ".$post['pagetext']."<br /><br />";

is it correct code ? I want to add it as plugin, but when I do it - is error with memory limit (I have 16M in php.ini)
