Database SQL query error

I am trying to run below query.

$sql = SELECT * FROM `wp_podsrel` WHERE `related_item_id` =$user-ID AND `pod_id` = 17  AND `field_id` = 25;

$results = $wpdb-get_results($sql) or die(mysql_error());

But I am getting error.

If I run the Query in phpMyAdmin it is working fine.
