What if the product ids are more than one?

What if the product ids are more than one?

AND order_item_meta.meta_value IN ($product_ids)

What if you only want one variation of a product?

What if you only want one variation of a product?

AND order_item_meta.meta_key = '_variation_id'
AND order_item_meta.meta_value = '$variation_id'

instead of

AND order_item_meta.meta_key = '_product_id'
AND order_item_meta.meta_value = '$product_id'

Thanks for this query BTW. Appreciate it!

Maybe this would be affected by HPOS?

The post_id in posts table will remain to assure compatibility although all the data will be out of post/postmeta so I think it will continue working without problems.

Hi, I want to sort products by order count, how change this query to achieve all products order count and sort them?

I found that

query =  "
        SELECT count(order_items.order_id) as order_count, order_item_meta.meta_value as product_id
        FROM {$wpdb->prefix}woocommerce_order_items as order_items
        LEFT JOIN {$wpdb->prefix}woocommerce_order_itemmeta as order_item_meta ON order_items.order_item_id = order_item_meta.order_item_id
        LEFT JOIN {$wpdb->posts} AS posts ON order_items.order_id = posts.ID
        WHERE posts.post_type = 'shop_order'
        AND posts.post_status = 'wc-completed'
        AND order_items.order_item_type = 'line_item'
        AND order_item_meta.meta_key = '_product_id'
        GROUP BY product_id
        ORDER BY order_count DESC";

Thankyou lukecav for the query
