On what date did the Du monde entier company request that 9 units of Filo Mix be sent to it?
9 units of Filo Mix refer to ProductName where Quantity = 9; Du monde entier is the name of the customer; date refers to OrderDate;
SELECT T2.OrderDate FROM Customers AS T1 INNER JOIN Orders AS T2 ON T1.CustomerID = T2.CustomerID INNER JOIN `Order Details` AS T3 ON T2.OrderID = T3.OrderID INNER JOIN Products AS T4 ON T3.ProductID = T4.ProductID WHERE T4.ProductName = 'Filo Mix' AND T3.Quantity = 9 AND T1.CompanyName = 'Du monde entier'
