I am using Microsoft SQL Server 2005. I need to know the most recent date/time  when each table was last opened. Is there a utility or query that can provide this information ?

What you mean by opened ?  if it is last queried, you are not lucky, there is no such option in sql server . If it is last time the table structure was modified, you can check the sysobjects table.

Use below query to get the info.

Note - Groups is the table Name-

--

SELECT 
name TableName, create_date CreatedDate ,modify_date ModifiedDate, *
FROM SYS.TABLES
WHERE name = 'Groups'


--

Open in new window



o/p

TableName      CreatedDate      ModifiedDate      name      object_id      principal_id      schema_id      parent_object_id      type      type_desc      create_date      modify_date
Groups      2016-11-01 18:02:53.963      2016-11-01 18:02:53.963      Groups      267147997      NULL      1      0      U       USER_TABLE      2016-11-01 18:02:53.963      2016-11-01 18:02:53.963


Try2... for more details.. you should use sys.dm_db_index_usage_stats

--

SELECT DB_NAME(k.[database_id]) DB, OBJECT_NAME(k.[object_id]) TableName, MAX(k.[last_user_lookup]) LastLookUp, MAX(k.[last_user_scan]) LastScan,
MAX(k.[last_user_seek]) LastSeek FROM sys.dm_db_index_usage_stats AS k
WHERE k.[database_id] = DB_ID()
AND k.[object_id] = OBJECT_ID('Groups')
GROUP BY k.[database_id], k.[object_id];


--

Open in new window


o/p

DB                              TableName      LastLookUp      LastScan                              LastSeek
ABCInvestment      Groups               NULL              2016-11-01 18:46:40.443      NULL


Hope it helps !!

Unfortunately, I did mean queried and not all tables are indexed so it looks like I'm out of luck.

No further question, as you said "if it is last queried, you are not lucky, there is no such option in sql server".
