$mylink = $wpdb->get_row( "SELECT * FROM $wpdb->links WHERE link_id = 10" );

// columns from the table $wpdb->links with the values of the table fields:
echo $mylink->link_id; // display "10"
0

#2 Using a constant: 

$mylink = $wpdb->get_row( "SELECT * FROM $wpdb->links WHERE link_id = 10", ARRAY_A );
