Question of the Day

A Quick Restore

While doing some testing of an application, I wanted to reset my environment after doing some testing with this code:

USE DNRTest

BACKUP DATABASE DNRTest TO DISK = 'dnrtest.bak'
GO
/*
Bunch of stuff tested here
*/RESTORE DATABASE DNRTest FROM DISK = 'dnrtest.bak' WITH REPLACE
What happens if this runs, assuming the "bunch of stuff" isn't anything affecting the instance.
