Before you can tackle any performance issues with a working database, you need to know which queries to work on first: The ones that are taking the most time in total, and which are the most expensive in terms of cache, CPU and disk.

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
