There are some skills which are extensions of your instincts, and which you can only learn though years of experience. Matt Simmons has this brought home by the fact that he was recently minutes away from a data-loss disaster, and he doesn't quite know how he prevented it.
A disaster can easily lead to another disaster. Can you respond to multiple problems? Have you even considered the cascade effects of a large disaster?
A real world account of disaster recovery. (This article is being republished after the recent hurricane that hit the US East Coast).
The backup and restore system in SQL Server hasn't changed a great deal over the years despite a huge growth in the typical size of databases. When disaster strikes, and an important service is taken offline while a restore is performed, there is often time to reflect on whether it might be possible to design databases for a more rapid recovery of the most critical parts of a database application.
A suggested design for creating flight schedules makes querying easy. Includes basic airport and airlines data. Get started now with this tricky query problem.
Part of an effective response to a disaster situation is practice and testing of your skills and procedures. Steve Jones reminds us this is important today.
During presentations about doing database backups and restores, there seem to be two two types of questions that are commonly asked, Those that come from the floor during the presentation, and those that are asked in private afterwards. These are sometimes more interesting, and challenging to answer well.
This paper provides a foundation for understanding data replication as well as a discussion of the criteria for selecting an appropriate replication technology.
When a disaster strikes, how will you respond? Will you not only successfully recover, but will you do so with professionalism and grace under pressure? Steve Jones tells you how you can.

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
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
