When was CheckDB last run?

There’s a whole bunch of scripts out there that show the history of when dbcc checkdb was last run. Many are inaccurate. Here’s the one I use …

--checkdb_history.sql
CREATE TABLE #DBInfo_LastKnownGoodCheckDB
	(
		ParentObject varchar(1000) NULL,
		Object varchar(1000) NULL,
		Field varchar(1000) NULL,
		Value varchar(1000) NULL,
		DatabaseName varchar(1000) NULL
	)

DECLARE csrDatabases CURSOR FAST_FORWARD LOCAL FOR
SELECT name FROM sys.databases WHERE name NOT IN ('tempdb')

OPEN csrDatabases

DECLARE
	@DatabaseName varchar(1000),
	@SQL varchar(8000)

FETCH NEXT FROM csrDatabases INTO @DatabaseName

WHILE @@FETCH_STATUS = 0
BEGIN
	--Create dynamic SQL to be inserted into temp table
	SET @SQL = 'DBCC DBINFO (' + CHAR(39) + @DatabaseName + CHAR(39) + ') WITH TABLERESULTS'

	--Insert the results of the DBCC DBINFO command into the temp table
	INSERT INTO #DBInfo_LastKnownGoodCheckDB
	(ParentObject, Object, Field, Value) EXEC(@SQL)

	--Set the database name where it has yet to be set
	UPDATE #DBInfo_LastKnownGoodCheckDB
	SET DatabaseName = @DatabaseName
	WHERE DatabaseName IS NULL

FETCH NEXT FROM csrDatabases INTO @DatabaseName
END

--Get rid of the rows that I don't care about
DELETE FROM #DBInfo_LastKnownGoodCheckDB
WHERE Field != 'dbi_dbccLastKnownGood'

SELECT Distinct
	DatabaseName,
	Value  as LastGoodCheckDB--,
	--DATEDIFF(dd, CAST(Value AS datetime), GetDate()) AS DaysSinceGoodCheckDB,
	--DATEDIFF(hh, CAST(Value AS datetime), GetDate()) AS HoursSinceGoodCheckDB
FROM #DBInfo_LastKnownGoodCheckDB
ORDER BY DatabaseName

DROP TABLE #DBInfo_LastKnownGoodCheckDB
