Updating column and insert a row - sql

Question

I am trying to accomplish to update the column ListPrice adding 25 to its current value where the name is All-Purpose Bike Stands and update SellStartDate to tomorrow's date in the table Production.Product.
Using that updated price I want to insert a row into the table Production.ProductListHistory with the new ListPrice and also update the row in the Production.ProductHistory column named EndDate with tomorrow's date as well.
The tables definitions areas follows:
Production.Product:
ProductID int PK
Name varchar(50)
ProductNumber nvarchar(25)
ListPrice money
SellStartDate datetime
SellEndDate
Production.ProductListHistory:
ProductID int PK FK
StartDate datetime PK
EndDate datetime
ListPrice money
Here is what I have so far that continues to give me errors:
CREATE PROCEDURE UPDATE_AND_INSERT
(#newprice money)
AS
BEGIN
UPDATE AdventureWorks2008R2.Production.Product
SET #newprice = 25 + AdventureWorks2008R2.Production.Product.ListPrice
WHERE AdventureWorks2008R2.Production.Product.Name LIKE 'All-Purpose%'
#newprice = AdventureProduct.Production.Listprice
END

Answer 1

If I understood your question, Your UPDATE should be something like this
You can also create a table variable to store your deleted list price and then insert it into your history table
DECLARE #MyTableVar table(
ProductID int NOT NULL,
StartDate datetime,
EndDate datetime,
ListPrice money);
UPDATE AdventureWorks2008R2.Production.Product
Set ListPrice = 25 + AdventureWorks2008R2.Production.Product.ListPrice
OUTPUT inserted.ProductID,
inserted.SellStartDate,
inserted.SellEndDate,
deleted.ListPrice
INTO #MyTableVar
where AdventureWorks2008R2.Production.Product.Name Like 'All-Purpose%'
AND Listprice = AdventureProduct.Production.Listprice
