Question of the Day
The Tightly Linked View
I try to run this code on SQL Server 2022. All the objects exist in the database.
CREATE OR ALTER VIEW OrderShipping
AS
SELECT cl.CityNameID,
cl.CityName,
o.OrderID,
o.Customer,
o.OrderDate,
o.CustomerID,
o.cityId
FROM dbo.CityList AS cl
INNER JOIN dbo.[Order] AS o ON o.cityId = cl.CityNameID
GO
CREATE OR ALTER FUNCTION GetShipCityForOrder
(
@OrderID INT
)
RETURNS VARCHAR(50)
WITH SCHEMABINDING
AS
BEGIN
DECLARE @city VARCHAR(50);
SELECT @city = os.CityName
FROM dbo.OrderShipping AS os
WHERE os.OrderID = @OrderID;
RETURN @city;
END;
go
