在wordpress中进行查询？

Question

I am editing an index.php file in the themes folder and I just need to run a query but I cant seem to run a query...here is what i tried

i tried to include the config files

<?php require( dirname(__FILE__) . '/wp-load.php'); ?> 
<?php print DB_NAME;exit; ?>

that printed nothing

then i tried to do the mysql_query command

mysql_connect($server, $username, $password)
$users = mysql_query("select * ....");
print_r($users); exit;

nothing in either one....i know there has got to be an easier way to do a query in wordpress...any ideas

Don't use mysql directly (as a mysql connection already exists). Instead use the wpdb 'abstraction' - see the wordpress documentation here: http://codex.wordpress.org/Function_Reference/wpdb_Class
