I’ve a scenario where I’ve to send a mail after checking a condition after every insert in a table.
- Is trigger the right way to do it?
My second question would be as to what approach to take
-
Should I directly send a mail from the DB. (Note: My DBserver and Mail server are in different networks, might’ve to create firewall rule exception)
-
Should I have a CLR-sproc. From the DB, I call the CLR-sproc and CLR-sproc calls a service and from there sends the mail.
Is there a better approach?
Both SQL Server DBMail and a CLR proc will use SMTP to send the email. So, why add complexity?
In addition, sending an email via DBMail or CLR will require processing on INSERT. Note that DBMail uses a queue so will impact less than running a CLR procedure.
A trigger is a good way to do it. However, consider using a stored procedure to do the ISNERT with the email sent outside of the transaction (you’ll have an implicit one because of the INSERT). Sending in a trigger means it is part of the implicit transaction for the INSERT.
From a security perspective, SQLMachine still needs access to SMTPMachine, whether using DBMail or a service call by a CLR Proc.
