Suntra's solution works, but this one adds a few more things.
<?php // Never use short tags.
$sql = "SELECT metaDescription, metaKeywords from General"; // First create the query string, easier to debug that way.
// echo $sql; // Debugging if needed
$query = mysql_query($sql) or die("Could not retrieve data\nError: ".mysql_error());
$meta = mysql_fetch_assoc($query);
?>
