Stored procedure to insert a list of different types of items in to a table - sql

Question

I have following two tables
CREATE TABLE Orders
(
OrderID int IDENTITY NOT NULL,
StaffID int NOT NULL,
TotalPrice money NOT NULL,
OrderDateTime dateTime NOT NULL
PRIMARY KEY (OrderID),
FOREIGN KEY (StaffID)
REFERENCES Staff(StaffID)
)
CREATE TABLE OrderDetails
(
OrderDetailID int IDENTITY NOT NULL,
OrderID int NOT NULL,
ItemID int,
ExtrasID int,
ItemQuantity int,
ExtrasQuantity int
PRIMARY KEY (OrderDetailID)
FOREIGN KEY (OrderID)
REFERENCES Orders(OrderID),
FOREIGN KEY (ExtrasID)
REFERENCES Extras(ExtrasID),
FOREIGN KEY (ItemID)
REFERENCES Item(ItemID)
)
I would like to create a stored procedure which will create a new order by inserting data in to both tables. This procedure should take the parameters for the StaffID, TotalPrice and the bought products. Products can be a many Items, many Extras or both.
Is there any way I can have a list of ItemID's and a list of ExtrasID's as the parameters which will then be inserted in to the OrderDetails table correctly?

Answer 1

Create a type first
CREATE TYPE dbo.ty_Product_Orders AS Table
(
ItemID INT
,ExtrasID INT
,ItemQuantity INT
,ExtrasQuantity INT
)
GO
Procedure Definition
Now make your procedure accept a parameter of that type.
CREATE PROCEDURE usp_Place_Order
#StaffID INT
,#TotalPrice MONEY
,#Order dbo.ty_Product_Orders READONLY
,#OrderPlaced BIT = 0 OUTPUT
AS
BEGIN
SET NOCOUNT ON;
-- table variable to hold the identity values
DECLARE #OrderDetails TABLE
(
OrderID INT,
ItemID INT
,ExtrasID INT
,ItemQuantity INT
,ExtrasQuantity INT
)
BEGIN TRY
BEGIN TRANSACTION;
-- Insert Orders
INSERT INTO Orders (StaffID , TotalPrice , OrderDateTime)
OUTPUT inserted.OrderID , inserted.ItemID ,inserted.ExtrasID ,
inserted.ItemQuantity ,inserted.ExtrasQuantity
INTO #OrderDetails(OrderID , ItemID , ExtrasID
,ItemQuantity ,ExtrasQuantity)
SELECT #StaffID , #TotalPrice , GETDATE()
FROM #Order
-- insert OrderDetails
INSERT INTO OrderDetails ((OrderID , ItemID , ExtrasID ,ItemQuantity ,ExtrasQuantity)
SELECT OrderID , ItemID , ExtrasID,ItemQuantity ,ExtrasQuantity
FROM #OrderDetails
COMMIT TRANSACTION;
END TRY
BEGIN CATCH
IF (##TRANCOUNT <> 0)
ROLLBACK TRANSACTION;
-- Other error logging here
END CATCH
END
