How to: Check the time of the last clean DBCC CHECKDB in SQL Server

DBCC CHECKDB is a common maintenance task executed to verify that the data stored in a SQL Server database is clean (i.e. not corrupt).  Generally speaking, it is good practice to run DBCC CHECKDB against any database that contains valuable data.  The one database where DBCC CHECKDB is not necessary is the tempdb database as the tempdb database is recreated from scratch every time that the SQL Server service is started.  All of the other system and user databases should be checked on a regular basis – if possible.

So, how do you know the last time DBCC CHECKDB was executed successfully against a given database?  Why with the following script of course!

Some time ago, Paul Randal published a post entitled “CHECKDB From Every Angle: When did DBCC CHECKDB last run successfully?.”  This gave us the raw internals to identify the last good DBCC CHECKDB run.  The script above simply wraps that information into an easy to consume report.

This is a great script to have in your toolbox – especially if you are new to an environment and you are trying to get a feel for the condition of the databases on a particular system.

That’s it for this post.  Please check back tomorrow for some more SQL Server / .NET goodness!
