Hi Experts,

I would like to set up an alert on a specific database table when a record is added to receive a report from SQL reporting services or at least some notification of a change in the table.
What is the best way of achieving this?

Thanks

Chris

What sort of alert? If you want an email, configure SQL to send email using xp_sendmail and send yourself an email using a trigger.

If this is a high load server then this isn't the best way to do this plus you will potentially get spammed.

Can you build a .Net application to monitor it? In that case, you could use SQLDependency. Check http://emoreau.com/Entries/Articles/2012/03/Using-SQL-Dependency-in-a-Net-application.aspx

Hi Ideally I would like a SSRS report to be sent by email (Which i would create)  if the database table is updated.  
How do I do this.  I am not familar with triggers and would like some guidance on how to set this up

Thanks

To me, the best way to do this is with Change Tracking.  It's built into SQL Server and will be far less overhead, with guaranteed accuracy, vs. anything you could write yourself.

I think you could build an SSRS report that used the change tracking functions to report changes to you as well.

Assuming that Scott is referring to CDC (Change Data Capture) you should be aware this is a Enterprise Edition only feature.

@Anthony:
"Change Tracking" does not require Enterprise Edition (CDC does indeed require it).
CT is also less overhead than CDC.


What is "immediately"?  Within one minute, five minutes, or to the second?

1-5 mins would be good

You can have a report that refreshes every 5 minutes that uses the Change Tracking function to see any row(s) that have been modified in the last 5 minutes (or maybe even since the report was last viewed by anyone).
