I have a scenario and that has to be achieved either in SQL or SSIS. Hope someone can help me out here:
Scenario: We get EmailNames from our Source Systems and adding them in a table at Staging. Now whenever any new email gets added to the existing emails, I should be notified.
Request you to please help me on how to achieve the same.

What is adding data to the staging table? Whether that is a job, a process, a person or something else, can you modify it so it sends you an email when new data is loaded?

Or is that the issue, can you not modify that process and you want to be notified by some other independent means?

My apologies, I should've been more specific about my problem.

I have SQL Job which loads the data into Staging from Source Flat Files using an SSIS Package. I cannot modify the data at Staging as I would require the same data for Production.

The data loading for Staging table is Truncate and Load. I have an idea which is I would copy my entire table into another table called Archive and will compare the distinct Mails in current Staging and Archive table so that I would get newly added Mails and this process will be automated thru some Script or SSIS Package.

However, I am thinking of any other approach apart from this. Any thoughts please

Do you permissions to run DDL and DML comnands on the table. If yes, have you considered adding a trigger?

Also, is the load incremental or full?

Yes, I do have full permissions. It's FULL Load that's why I didn't consider Triggers

If you are truncating and loading the tables then how will you find the new emails?, you have to have a archive table there you can load distinct values then you compare with the new values. once completed you can load new values again.;-)

Well, If you can check the entire thread - that's what my initial plan is however I am just curious if anyone can give me a better idea than having Archive table and comparing the values.

It sounds to me as if your proposed archive-table will, after the each set of staging data has been added to it, will be the superset of all emails that have ever been in production. That seems like the best way to determine if an email in the staging table is "new" to your system. A simple LEFT JOIN or NOT EXISTS from your staging table to your archive table should do fine.
