Introduction to SQL Server Filtered Indexes

  • Article

SQL Server filtered indexes can save space and improve performance if they are used properly. Under what circumstances can they be used? When are they most effective, and what sort of performance gain or space-saving is likely? How does a filtered index affect the choice of execution plan? Seth Delconte explores these questions with practical experiments.

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.
