Regular Expression Transformation

The regular expression transformation exposes the power of regular expression matching within the pipeline. One or more columns can be selected, and for each column an individual expression can be applied. If all columns selected pass their tests then rows are passed down the successful match output. Rows that fail to pass all tests are directed down the alternate output.

No Outlook for Alerts!

SQL Server 2000 has a fantastic subsystem for alerting the DBA and keeping him or her informed as to the state of the server. However the email subsystem introduces a dependency on Outlook for alerts that can be a problem for some environments. Author Roy Carlson brings us an ingenious method for reading logs and sending alerts without Exchange or Outlook.

Software patents: stupid or insane?

Lest the headline mislead you as to my biases, I consider software patents to be both stupid and insane. I raise this issue because it is currently rearing its ugly mug in the world of open source software, but it has affected much development in the proprietary worlds of Windows as well.

First of all, patent laws were created long ago, which is not to say the thinking was correct then either, but we have to recognize the intellectual and technological climate back then.

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
