ok i did a little bit more: i'm joining against all databases, so i can find things that were never accessed; on my test server i see a lot of db's that fit that description, and on production, there's just one database that hasn't been touched since the last reboot;all the others show dbs with more frequency.

hope this helps :

;;WITH myCTE AS

(

SELECT

DB_NAME(database_id) AS TheDatabase,

OBJECT_NAME(object_id,database_id) As TheTableName,

last_user_seek,

last_user_scan,

last_user_lookup,

last_user_update

FROM sys.dm_db_index_usage_stats

),AllDbs

AS

(

SELECT name AS TheDatabase from master.sys.databases

)

SELECT

ServerRestartedDate = (SELECT CREATE_DATE FROM sys.databases where name='tempdb'),

db.TheDatabase,

MAX(x.last_read) AS last_read,

MAX(x.last_write) AS last_write

FROM AllDbs db

LEFT OUTER JOIN

(

SELECT TheDatabase,TheTableName,last_user_seek AS last_read, NULL AS last_write FROM myCTE

UNION ALL

SELECT TheDatabase,TheTableName,last_user_scan, NULL FROM myCTE

UNION ALL

SELECT TheDatabase,TheTableName,last_user_lookup, NULL FROM myCTE

UNION ALL

SELECT TheDatabase,TheTableName,NULL, last_user_update FROM myCTE

) AS x

on db.TheDatabase = x.TheDatabase

GROUP BY db.TheDatabase

ORDER BY db.TheDatabase
