I just recently moved to WooCommerce platform and need to build SQL in MySQL to run my own analytical reports. For example, I need report that shows total number of sales per sku, per country in the last 30 days. I explored tables like 'wp_posts', 'wp_postmeta' and found that most fields from products and orders are record-based, not column based which makes the SQL a little more challenging.

Correct me if I'm wrong but I think you missed that each line item also has a quantity in wp_woocommerce_order_itemmeta
. So your query is just counting how many orders there are for each SKU and not how many of them were sold.

Finally built the SQL by myself. Hope it will be useful for other WooCommerce users who don't want to use analytical out-of-the box solutions or need custom reporting.
SELECT
sku, count(1)
FROM
wp_woocommerce_order_items oi, -- orders table
wp_posts p, -- woocommerce use posts to keep metadata on the order
wp_postmeta pm, -- we use this table to filter the completed orders
wp_postmeta pm1, -- we use this table again for getting the shipping country info
wp_woocommerce_order_itemmeta oim, -- use this table to get product ids from orders
(SELECT p.id as product_id, meta_value as sku FROM wp_posts p, wp_postmeta pm where
post_type='product' and post_status='publish'
and meta_key='_sku'
and p.id=pm.post_id) as sku_table -- building temp sku table from published products that defines relationship between product id and sku
WHERE
oim.meta_value=sku_table.product_id AND
oi.order_id=p.ID AND
p.id=pm.post_id AND
pm.meta_key='_paid_date' AND -- here we make sure that the order was completed
p.id=pm1.post_id AND
order_item_type='line_item' AND -- get only line items but not tax or shipping
oi.order_item_id=oim.order_item_id AND
oim.meta_key='_product_id' AND
post_date>'2014-01-01' AND -- limits the report date
pm1.meta_key='_shipping_country' AND -- get shipping country
pm1.meta_value='US' -- limits the country
GROUP BY sku
ORDER BY sku;
