Hi All,

I got one task related to database backups, it is like

When user tried to Delete a database in the server.

1) log the user id, DateTime in some Logtable.
2) Take backup of the database before it is deleted.

I know SQL Server have 'DDL Triggers' at server level and database level, I don't know how to use this related to the task given.

If any one know about this please help me.

Thanks in advance

You can create DDL trigger as
CREATE TRIGGER ddlTrigger
ON ALL SERVER
FOR DDL_LOGIN_EVENTS
AS
.. .. .
..

.


You can use EVENTDATA() function that returns info such as event time, SPID, and type of event firing the trigger in form of XML data.

Look for use of 'INSTEAD OF Triggers'. As triggers are of two types after and instead of. in your case 'instead of trigger' may work.
