[INST] Given a table of Customer orders with columns CustomerID, OrderID, and OrderDate, write a SQL query to find the first order date for each customer./n [/INST]  ###Response: You can use the MIN() function to find the earliest order date for each customer. Here is an example SQL query:

```
SELECT CustomerID, MIN(OrderDate) AS FirstOrderDate
FROM CustomerOrders
GROUP BY CustomerID;
```

This will group the orders by customer, and select the customer ID along with the earliest order date (aliased as "FirstOrderDate") for each group.
