Did you read the link provided with the answer? It explains about Dynamic Managent Views(DMV) and how to use them.

I must object the suggested answer.

It is possible to use 1-part names, although it does not really make sense to do this:

CREATE LOGIN Test WITH PASSWORD = 'Test123!'

CREATE USER [Test] FOR LOGIN [Test] WITH DEFAULT_SCHEMA=[sys]

GO

EXECUTE AS USER = 'Test'

SELECT * FROM all_views

REVERT

DROP USER Test

DROP LOGIN Test

?MSDN??:

In the MSDN :

Dynamic management views and functions return server state information that can be used to monitor the health of a server instance, diagnose problems, and tune performance.

??? DMV ??SQLServer ????? ??? SS ??????????? ???????????SS ??? ????select * from all_views ????????? ????DMV??

So DMV is a concept in the SS. it represents a kind of views and functions in the SS. these views and functions show some info that can be used to monitor the health of a server instance, diagnose problems, and tune performance.

in the "select * from all_views",which can be called as DMV.

is that right?
