Thread: function to send email with query results
Hi all:
I'm looking to write a function to send email with result of a query. Is it possible to send email with in a function. Any help is appreciated.
Thanks,

Yes...though neither the neither the sql nor the plpgsql languages have the necessary language features to do so - you will need to use something like plperlu.
An (not mutually exclusive) alternative is to create an email queue and write an email sending client application to process that queue. The main advantages being loose coupling and the ability to send the emails asynchronously.

Any help is appreciated. Only with functions written in untrusted languages, for instance pl/sh or pl/perlU. Not with pure SQL, no with pl/pgsql or similar.

If you go that route you might find LISTEN/NOTIFY useful: http://www.postgresql.org/docs/9.4/static/sql-listen.html -- Jim Nasby, Data Architect, Blue Treble Consulting Data in Trouble?

Using Apache camel
Listen/notify ->PGEvent Component (http://camel.apache.org/pgevent.html) -> Mail Component (http://camel.apache.org/mail.html)
You can also then handle all the exceptions of the email server easily.
