I am trying to export a customer list via phpmyadmin. I need to emails and names of customers that have ordered recently.

I can export zen_customer and it gives me all I need beside telling me if they have ever placed an order or not. Where is the order count stored for a customer? In zen admin I can see the customers number of logins and number of orders. Where is it stored? I would think I can merge the two tables somehow to create a list like I need.

Thanks
