For each category of product, please find, by customer’s country, the count of orders and how much revenue the customers have generated. Please also include a subtotal for each category plus a grand total. (HINT: Use ROLLUP)

Sure, I can help you with that! It sounds like you need to perform a grouped summary calculation with ROLLUP. Here's an example SQL query that should accomplish what you're asking for:
```
SELECT
product_category,
customer_country,
COUNT(order_id) AS order_count,
SUM(revenue) AS total_revenue
FROM
orders
GROUP BY
product_category,
customer_country WITH ROLLUP;
```
This query will group the orders by product category and customer country, and then calculate the count of orders and total revenue for each group. The WITH ROLLUP clause will also include subtotals for each product category and a grand total for the entire dataset.
Please note that you'll need to replace the table and column names in this query with the appropriate names from your own database. Also, be sure to adjust the column names in the SELECT statement to match your own table schema.
Let me know if you have any questions or if there's anything else I can help you with!
