Too often, denormalization is suggested as the first thing to consider when tackling query performance problems. It is said to be a necessary compromise to be made when a rigorous logical design hits an inadequate database system. As the saying goes, “Normalize ‘til it hurts, then denormalize ‘til it works”.

It is irritating, sometimes alarming, for the user to be confronted by the 'deadlock message' when a deadlock happens. It can be a tiresome business to prevent them from occurring in applications. Fortunately, the profiler can be used to help DBAs identify how deadlocking problems happen, and indicate the best way of minimising the likelihood of their reappearance.

While working on a project recently I was asked to develop a mechanism that would provide the dates for state and federal holidays in a given year. Since this project deals with all states and territories of the United States, the list had to be comprehensive and the client asked that this list be in the form of a SQL query calculated on-the-fly, rather than a static list.

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
exec('SELECT ProductName FROM product;')
END;
GO
exec etl.GettheProduct
When I execute this code as a user whose default schema is dbo and has rights to the tables and proc, what is returned? See possible answers
