Hello!
...the last chapter :)
"After a marked transaction commits, a row is inserted in the logmarkhistory table in msdb."
The practice from MSDN:
BEGIN TRANSACTION CandidateDelete
WITH MARK N'Deleting a Job Candidate';
GO
USE AdventureWorks2012;
GO
DELETE FROM AdventureWorks2012.HumanResources.JobCandidate
WHERE JobCandidateID = 13;
GO
COMMIT TRANSACTION CandidateDelete;
GO

Q1: Why is the logmarkhistory table still empty after successfull data deletion?
Thank you in advance,
Michael
