Keep your Resume Reasonable

The other day, I was in a Twitter discussion interviewing people for technical positions.

If you put it on the resume, I assume you know something about it and are willing […]

Question of the Day

Changing the Schema

I set up a few users on my SQL Server 2022 instance. 

CREATE LOGIN User1 WITH PASSWORD = 'Demo12#1'
CREATE USER User1 FOR LOGIN User1
GO
CREATE LOGIN User2 WITH PASSWORD = 'Demo12#2'
CREATE USER User2 FOR LOGIN User2
GO
CREATE LOGIN User3 WITH PASSWORD = 'Demo12#3'
CREATE USER User3 FOR LOGIN User3
GO
I then created a schema that one of them owned. Under this schema, I added a table with some data. 
CREATE SCHEMA MySchema AUTHORIZATION User1
GO
CREATE TABLE Myschema.MyTable(myid INT)
GO
INSERT MySchema.MyTable
(
    myid
)
VALUES
(1), (2), (3)
GO
SELECT * FROM MySchema.MyTable
GO
I granted rights and verified that User2 could access this table. 
GRANT SELECT ON Myschema.MyTable TO User2
GO
SETUSER 'USER2'
GO
SELECT * FROM MySchema.MyTable
GO
This worked. Now, I move this schema to a new user. 
ALTER AUTHORIZATION ON SCHEMA::Myschema TO User3;
GO
What happens with this code? 
SETUSER 'USER2'
GO
SELECT * FROM MySchema.MyTable
GO
