I'm using the following code to pull the total number of products in a given category sold:
get_post_meta($product_id='17', 'total_sales', true );
The problem is that the number is not accurate, as it includes orders that I moved to the trash, and then permanently deleted, in the woocommerce admin interface. Is there a way to completely purge those orders from the database, through the interface? If not, can you guys help me with the syntax to clear out the appropriate data from the appropriate tables? I looked through the tables a bit and think I know what needs to go, but would rather have an assist.
