Object's modified date

There are lots of businesses have already upgraded to SQL Server 2005.At this time I'd like to take a look at great feature that we have in SQL Server 2005. I have been asked so many times how to know WHEN does the object change? It is a headache in SQL Server 2000. Fortunately, now we can answer that question.

Let's say the user changed number of stored procedures.Using the following statement we can easily get the data.

SELECT name,modify_date FROM sys.procedures
ORDER BY modify_date desc

But let's take it a little bit futher. I'd like to know when does user update the table last time?

CREATE TABLE dbo.uri(c INT NOT NULL PRIMARY KEY)
GO
INSERT INTOdbo.uri VALUES(10)
--we got one entry

SELECT object_name(object_id) AS name ,last_user_update
FROM sys.dm_db_index_usage_stats
WHERE database_id = db_id( 'demo' )

---try to change the data
UPDATE dbo.uri SET c =50 WHERE c =10

--you'll see that last_user_update is changed

SELECT object_name(object_id) AS name ,last_user_update
FROM sys.dm_db_index_usage_stats
WHERE database_id = db_id( 'demo' )

So ,you can play with these Dynamic Management Views to obtain more info.
