Last Time CheckDB was Run

By Jason Brimhall, 2013/01/17

Corrupt PagesBack in November 2012, I shared a story about checking the last known good checkdb in the boot page of a database.  You can read that story here.

This is an important enough topic that it is worth repeating frequently if I wanted to do that.  If  for no other reason than to continue to hammer at how important it is to both run checkdb and know the last time that checkdb was run successfully.

Alas, I am writing to fix a few things with the script that I shared in that last past.

I run this script on every server I touch to get a report for the last known good checkdb for every single database.  I had been running the script flawlessly across many servers without error.  Then it happened.  The script failed with a nasty error.

After a bit of looking, it became apparent my flaw in the script.  I had not written the script with CS (case sensitivity) in mind.  I touch so few CS servers, that I sometimes forget to check for that.  Slap my hands and I will work on that going forward.

So here is the update to the script.

Code block   
CREATE TABLE #temp (
       Id INT IDENTITY(1,1), 
       ParentObject VARCHAR(255),
       [OBJECT] VARCHAR(255),
       Field VARCHAR(255),
       [VALUE] VARCHAR(255)
)
 
CREATE TABLE #DBCCRes (
       Id INT IDENTITY(1,1)PRIMARY KEY CLUSTERED, 
       DBName sysname ,
       dbccLastKnownGood DATETIME,
       RowNum	INT
)
 
DECLARE
	@DBName SYSNAME,
	@SQL    VARCHAR(512);
 
DECLARE dbccpage CURSOR
	LOCAL STATIC FORWARD_ONLY READ_ONLY
	FOR SELECT name
		FROM sys.databases
	WHERE 1 = 1
		AND STATE = 0
		--And name NOT IN ('tempdb')
	;
 
OPEN dbccpage;
FETCH NEXT FROM dbccpage INTO @DBName;
WHILE @@FETCH_STATUS = 0
BEGIN
	SET @SQL = 'Use [' + @DBName +'];' + CHAR(10)+ CHAR(13)
	SET @SQL = @SQL + 'DBCC Page ( ['+ @DBName +'],1,9,3) WITH TABLERESULTS;' + CHAR(10)+ CHAR(13)
 
	INSERT INTO #temp
		EXECUTE (@SQL);
	SET @SQL = ''
 
	INSERT INTO #DBCCRes
			( DBName, dbccLastKnownGood,RowNum )
		SELECT @DBName, VALUE
				, ROW_NUMBER() OVER (PARTITION BY Field ORDER BY VALUE) AS Rownum
			FROM #temp
			WHERE Field = 'dbi_dbccLastKnownGood';
 
	TRUNCATE TABLE #temp;
 
	FETCH NEXT FROM dbccpage INTO @DBName;
END
CLOSE dbccpage;
DEALLOCATE dbccpage;
 
SELECT DBName,dbccLastKnownGood
	FROM #DBCCRes
	WHERE RowNum = 1;
 
DROP TABLE #temp
DROP TABLE #DBCCRes
