Query Post Meta Value Based on dynamic date range - mysql

Question

I am looking to modify the default woocommerce Subscriptions by Product SQL query to only reflect the subscriptions product count for subscriptions that have a meta key = _schedule_next_payment and meta value within the next 7 days. The reason for this is I deliver product on a weekly basis and am trying to forecast all products that will likely be ordered in the next week.
I added the following query segment
LEFT JOIN (
SELECT *
FROM {$wpdb->posts} as subscriptionjk
INNER JOIN {$wpdb->postmeta} AS postmeta
ON subscriptionjk.id = postmeta.post_id
WHERE postmeta.meta_key = '_schedule_next_payment'
AND postmeta.meta_value BETWEEN '2020-09-07 00:00:00' AND '2020-09-14 00:00:00'
inside the default woocommerce query for class-wcs-report-subscriptions-by-product which generates the Subscriptions by Product report
"SELECT product.id as product_id,
product.post_parent as parent_product_id,
product.post_title as product_name,
mo.product_type,
COUNT(subscription_line_items.subscription_id) as subscription_count,
SUM(subscription_line_items.product_total) as recurring_total
FROM {$wpdb->posts} AS product
LEFT JOIN (
SELECT tr.object_id AS product_id, t.slug AS product_type
FROM {$wpdb->prefix}term_relationships AS tr
INNER JOIN {$wpdb->prefix}term_taxonomy AS x
ON ( x.taxonomy = 'product_type' AND x.term_taxonomy_id = tr.term_taxonomy_id )
INNER JOIN {$wpdb->prefix}terms AS t
ON t.term_id = x.term_id
) AS mo
ON product.id = mo.product_id
LEFT JOIN (
SELECT wcoitems.order_id as subscription_id, wcoimeta.meta_value as product_id, wcoimeta.order_item_id, wcoimeta2.meta_value as product_total
FROM {$wpdb->prefix}woocommerce_order_items AS wcoitems
INNER JOIN {$wpdb->prefix}woocommerce_order_itemmeta AS wcoimeta
ON wcoimeta.order_item_id = wcoitems.order_item_id
INNER JOIN {$wpdb->prefix}woocommerce_order_itemmeta AS wcoimeta2
ON wcoimeta2.order_item_id = wcoitems.order_item_id
WHERE wcoitems.order_item_type = 'line_item'
AND ( wcoimeta.meta_key = '_product_id' OR wcoimeta.meta_key = '_variation_id' )
AND wcoimeta2.meta_key = '_line_total'
) as subscription_line_items
ON product.id = subscription_line_items.product_id
LEFT JOIN (
SELECT *
FROM {$wpdb->posts} as subscriptionjk
INNER JOIN {$wpdb->postmeta} AS postmeta
ON subscriptionjk.id = postmeta.post_id
WHERE postmeta.meta_key = '_schedule_next_payment'
AND postmeta.meta_value BETWEEN '2020-09-07 00:00:00' AND '2020-09-14 00:00:00'
) as subscriptions
ON subscriptions.ID = subscription_line_items.subscription_id
WHERE product.post_status = 'publish'
AND ( product.post_type = 'product' OR product.post_type = 'product_variation' )
AND subscriptions.post_type = 'shop_subscription'
AND subscriptions.post_status NOT IN( 'wc-pending', 'trash' )
GROUP BY product.id
ORDER BY COUNT(subscription_line_items.subscription_id) DESC" );
With that function as is it works and delivers the results I am looking for. However I have tried replacing those hard coded dates with a BETWEEN function using guidance from this stack overflow question and with different configurations I am trying it delivers no results.
I have tried this:
AND postmeta.meta_value BETWEEN GETDATE() AND DATEADD(day, -7, GETDATE())

Here is the solution that worked:
LEFT JOIN (
SELECT *
FROM {$wpdb->posts} as subscriptionjk
INNER JOIN {$wpdb->postmeta} AS postmeta
ON subscriptionjk.id = postmeta.post_id
WHERE postmeta.meta_key = '_schedule_next_payment'
AND postmeta.meta_value BETWEEN CURDATE() AND (CURDATE() + INTERVAL 7 DAY)
) as subscriptions
ON subscriptions.ID = subscription_line_items.subscription_id
