$wpdb in new OOP plugin

Hi I'm trying to write my first Wordpress plugin. I'm using classes to make it easier to maintain.

I'm wondering how I can use the WPDB class in my wordpress plugin.


$wpdb is a global variable, which is an instantiation of the class already set up to talk to the WordPress database.

you can use it in this manner -

global $wpdb;
$result = $wpdb->get_row( "SELECT value FROM ".$wpdb->prefix."plg_table" );
echo $result;
