Good job! Let's do one more exercise.
Exercise
For each employee, find the percentage of all orders they processed that were placed by customers in France. Show five columns: first_name, last_name, count_france, count_all, and percentage_france (rounded to one decimal point).
Note: To find the country where a customer is based, use the country column from the customers table.
Stuck? Here's a hint!
To find customers from France, join the orders and customers tables. Use the country column from the latter table.
You will also need the employees table.
Remember to group by employee_id, first_name, and last_name.
To calculate percentages, you should divide the numerator by the denominator and then multiply it by 100. Remember to round the result to one decimal point.
