Get all emails from customers that placed an order

Hi there,

The easiest way to get the billing email address a customer that was used during checkout is to export that into a CSV file. While there are quite a few plugins available for that, common ones include:

• https://woocommerce.com/products/ordercustomer-csv-export/
• https://wpallimport.com/ (It does have an export function)

Thanks for the reply,

but is there any chance to have this via an sql querry?
Because spending about 80-100 bucks for a one time action is not what I′m looking for
