sql statement writing

P: 553

I have following SQL Queries. Is there a way to to write a single query instead somehow instead?

-Get OrderID from this query
SELECT OrderID FROM Orders WHERE CustomerID='" + reader.Item("CustomerID")

-Using OrderID, get ProductID
"SELECT ProductID FROM OrderDetails WHERE OrderID=" + readerp.Item("OrderID")

-Using ProductID, get Products
SELECT ProductName FROM Products WHERE ProductID=" + reader1.Item("ProductID")

My question is instead of quering three times, can i write a single SQL statemnt to get the final result - (ProductName)
