Find the last time table was updated

Question

I want to retrieve the last time table was updated(insert,delete,update).

I tried this query.

SELECT last_user_update
FROM sys.dm_db_index_usage_stats
WHERE object_id=object_id('T')

but the data there is not persisted across service restarts.

I want to preserve the stats even if the service restarts. How can I achieve it?

Answer 1

If you're talking about last time the table was updated in terms of its structured has changed (new column added, column changed etc.) - use this query:

SELECT name, [modify_date] FROM sys.tables

If you're talking about DML operations (insert, update, delete), then you either need to persist what that DMV gives you on a regular basis, or you need to create triggers on all tables to record that "last modified" date - or check out features like Change Data Capture in SQL Server 2008 and newer.

Answer 2

If you want to see data updates you could use this technique with required permissions:

SELECT OBJECT_NAME(OBJECT_ID) AS DatabaseName, last_user_update,*
FROM sys.dm_db_index_usage_stats
WHERE database_id = DB_ID( 'DATABASE')
AND OBJECT_ID=OBJECT_ID('TABLE')

Answer 3

To persist audit data regarding data modifications, you will need to implement a DML Trigger on each table that you are interested in. You will need to create an Audit table, and add code to your triggers to write to this table.

For more details on how to implement DML triggers, refer to this MDSN article http://msdn.microsoft.com/en-us/library/ms191524%28v=sql.105%29.aspx

Answer 4

SELECT so.name,so.modify_date

FROM sys.objects as so

INNER JOIN INFORMATION_SCHEMA.TABLES as ist

ON ist.TABLE_NAME=so.name where ist.TABLE_TYPE='BASE TABLE' AND 

TABLE_CATALOG='DbName' order by so.modify_date desc;

this is help to get table modify with table name

Find last time of update on a table

`SELECT
tbl.name
,ius.last_user_update
,ius.user_updates
,ius.last_user_seek
,ius.last_user_scan
,ius.last_user_lookup
,ius.user_seeks
,ius.user_scans
,ius.user_lookups
FROM
sys.dm_db_index_usage_stats ius INNER JOIN
sys.tables tbl ON (tbl.OBJECT_ID = ius.OBJECT_ID)
WHERE ius.database_id = DB_ID()
`

Answer 6

Why not just run this: No need for special permissions

SELECT
    name, 
    object_id, 
    create_date, 
    modify_date
FROM
    sys.tables 
WHERE 
    name like '%yourTablePattern%'
ORDER BY
    modify_date

Answer 7

SELECT SCN_TO_TIMESTAMP(MAX(ora_rowscn)) from my_table;

The above command gives you the last timestamp when the table data was modified.

ORA_ROWSCN : For each row, ORA_ROWSCN returns the conservative upper bound system change number (SCN) of the most recent change to the row.
