If you want counts by customer then you need to specify the customer id in WHERE
condition.
E.g. if customer id is present in wntl_virtuemart_order_items
table then your query will look like this:
SELECT order_item_name, SUM(product_quantity)
FROM wntl_virtuemart_order_items
WHERE wntl_virtuemart_order_items.order_item_sku BETWEEN 2 and 2.9 AND order_status= 'U' AND customer_id = ?
GROUP BY order_item_sku
If customer id is present in another table then you will need to use JOIN
two tables like the below example:
SELECT order_item_name, SUM(product_quantity)
FROM wntl_virtuemart_order_items JOIN wntl_virtuemart_orders ON wntl_virtuemart_order_items.virtuemart_order_id = wntl_virtuemart_orders.virtuemart_order_id
WHERE wntl_virtuemart_order_items.order_item_sku BETWEEN 2 and 2.9 AND wntl_virtuemart_order_items.order_status= 'U' AND wntl_virtuemart_orders.customer_number = ?
GROUP BY order_item_sku
