That’s pretty cool.

Yeah. I was seeing that bug. I had to back all the way out and examine the DBCC Page results to confirm on a single database to make sure it wasn’t something I had done. But the rownum was an easy enough fix.

Correction..Looks like the bug still happens with DBCC Page (I tested on a 2005 server by mistake), but I see that’s why you select WHERE RowNum = 1…

I actually wrote similar code and it got added to Brent Ozar’s sp_blitz procedure. Someone found a bug – not in my code, but in the output of DBCC DBInfo, which returns a row for dbi_dbccLastKnownGood twice in SQL 2008+. Looks like your version using DBCC Page doesn’t suffer from this problem. Nice.

I waffled on filtering out offline databases or not. I’ll add it in. I was excluding tempdb only because each time the instance is restarted, boot page is restored and the dbi_dbccLastKnownGood is restored back to 1/1/1900.
But I agree that tempdb can be corrupt and if the server hasn’t been restarted for a while then we need to know the last time checkdb was run against tempdb. I’ll change that filter.

Great script. I’ve been meaning to rewrite mine as it uses sp_msforeachdb which has problems.

Just curious, why do you filter out tempdb? Tempdb can get corrupted too.

One suggestion, it fails if there is a database offline (mirror, log shipping secondary, etc). Recommend adding “state = 0″ to the query of sys.databases.
