ENDExplain the Stored Procedure
Stored Procedure :
A stored procedure is a prepared SQL code that you can save,
so the code can be reused over and over again.
So if you have an SQL query that you write over and over again,
save it as a stored procedure, and then just call it to execute it.
You can also pass parameters to a stored procedure,
so that the stored procedure can act based on the parameter value(s)
that is passed.create proc
IF OBJECT_ID ( 'Production.uspGetList', 'P' ) IS NOT NULL
DROP PROCEDURE Production.uspGetList;
GO
CREATE PROCEDURE Production.uspGetList @Product varchar(40)
, @MaxPrice money
, @ComparePrice money OUTPUT
, @ListPrice money OUT
AS
SET NOCOUNT ON;
SELECT p.[Name] AS Product, p.ListPrice AS 'List Price'
FROM Production.Product AS p
JOIN Production.ProductSubcategory AS s
ON p.ProductSubcategoryID = s.ProductSubcategoryID
WHERE s.[Name] LIKE @Product AND p.ListPrice < @MaxPrice;
-- Populate the output variable @ListPprice.
SET @ListPrice = (SELECT MAX(p.ListPrice)
FROM Production.Product AS p
JOIN Production.ProductSubcategory AS s
ON p.ProductSubcategoryID = s.ProductSubcategoryID
WHERE s.[Name] LIKE @Product AND p.ListPrice < @MaxPrice);
-- Populate the output variable @compareprice.
SET @ComparePrice = @MaxPrice;
