A Case Study in Performance Tuning

SQL Server does a wonderful job of tuning itself, selecting the optimum query plans and in general performing very well under a variety of conditions. That does not mean the a good DBA cannot add value by setting up the system and ensuring the optimizer receives the information that it needs. New author Gordon Pollokoff brings us a short case study from a project he as recently involved in where a new application required a bit of tuning.

Question of the Day

Which Table I

I have this code in SQL Server 2022: 

CREATE SCHEMA etl;
GO
CREATE TABLE etl.product
(
    ProductID INT,
    ProductName VARCHAR(100)
);
GO
INSERT etl.product
VALUES
(2, 'Bee AI Wearable');
GO
CREATE TABLE dbo.product
(
    ProductID INT,
    ProductName VARCHAR(100)
);
GO
INSERT dbo.product
VALUES
(1, 'Spiral College-ruled Notebook');
GO
CREATE OR ALTER PROCEDURE etl.GettheProduct
AS
BEGIN
    SELECT  ProductName
    FROM product;
END;
GO
When I execute this code as a user whose default schema is dbo and has rights to the tables and proc, what is returned?
