Last 2 orders by customer

I need to select the last 2 orders and dates by customer from a sales order table.

The table would have the customer number, docdate, order amount, order number etc..

Not quite sure the easiest way to do that.

Thanks

Couple of different ways to do this, but simplest is to use the RANK() keyword to rank all orders for each customer by the order date, then pick the top two.

Table and column names are samples, change these names to fit your situation.
SELECT CustomerID, OrderID, RankOrder
FROM (
   SELECT CustomerID, OrderID, 
     RANK() OVER (PARTITION BY CustomerID ORDER BY OrderDate DESC) as RankOrder
   FROM SalesOrderTable) a
WHERE RankOrder <= 2
