Query Help with Parent, Child, Child's Child

Question

Hi all,
Need some help with a query.  I'm trying to create a stored procedure that is sort of like a Customer, Order, Order, Details.  In my situation the tables are different but nevertheless, I want to grab all the fields from the  Parent, Child,
and Childs' Child, where the Parent.ParentID = @Parameter.  I tried this:
CREATE PROCEDURE [dbo].[spGetCompleteProjectXML]
@ProjectID int = 0
AS
SELECT *,
(SELECT *,
(SELECT *
FROM PageControls
WHERE (PageControls.ProjectPageID = ProjectPages.ProjectPageID))
FROM ProjectPages
WHERE (ProjectPages.ProjectID = @ProjectID))
FROM Projects
WHERE (ProjectID = @ProjectID)
FOR XML AUTO, ELEMENTS
RETURN 0
I think I'm close, but it was my best effort.  Could someone help?
thanks in advance

Hi TPolo,
Regarding your description, are you looking for a sample like below?
CREATE TABLE customer(customerID INT, name VARCHAR(99))
INSERT INTO customer VALUES(1,'Eric')
INSERT INTO customer VALUES(2,'Nelson')
CREATE TABLE orders(orderID INT,customerID INT)
INSERT INTO orders VALUES(1,1);
INSERT INTO orders VALUES(2,1)
INSERT INTO orders VALUES(3,2)
INSERT INTO orders VALUES(4,2)
CREATE TABLE orderDetails(orderID INT,item VARCHAR(99))
INSERT INTO orderDetails VALUES(1,'APPLE1')
INSERT INTO orderDetails VALUES(1,'BANANA1')
INSERT INTO orderDetails VALUES(2,'APPLE2')
INSERT INTO orderDetails VALUES(2,'BANANA2')
INSERT INTO orderDetails VALUES(3,'APPLE3')
INSERT INTO orderDetails VALUES(3,'BANANA3')
INSERT INTO orderDetails VALUES(4,'APPLE4')
INSERT INTO orderDetails VALUES(4,'BANANA5')
SELECT customer.customerID,customer.name,
(SELECT orderId,
SELECT item FROM orderDetails WHERE orderID=orders.orderID FOR XML AUTO,TYPE,ELEMENTS
FROM orders Where customerID=customer.customerID FOR XML AUTO,TYPE,ELEMENTS)
FROM customer WHERE customerID=1
FOR XML AUTO,ELEMENTS
DROP TABLE customer,orderDetails,orders
