SQL Server – How to get last access/update time for a table

Modify date and create date for a table can be retrieved from sys.tables catalog view. When any structural changes are made the modify date is updated. It can be queried as follows:


USE [SqlAndMe]
GO

SELECT    [TableName] = name,
create_date,
modify_date
FROM    sys.tables
WHERE    name = 'TransactionHistoryArchive'
GO

 

 

sys.tables only shows modify date for structural changes. If we need to check when was the tables last updated or accessed, we can use dynamic management view sys.dm_db_index_usage_stats. This DMV returns counts of different types of index operations and last time the operation was performed.

It can be used as follows:


USE [SqlAndMe]
GO

SELECT    [TableName] = OBJECT_NAME(object_id),
last_user_update, last_user_seek, last_user_scan, last_user_lookup
FROM    sys.dm_db_index_usage_stats
WHERE    database_id = DB_ID('SqlAndMe')
AND        OBJECT_NAME(object_id) = 'TransactionHistoryArchive'
GO

 

 

last_user_update – provides time of last user update

last_user_* – provides time of last scan/seek/lookup

It is important to note that sys.dm_db_index_usage_stats counters are reset when SQL Server service is restarted.

 

Hope This Helps!
