Looking for ideas.  I want a trigger to...
1) compose an html report based on DB content
2) email the report to a dist list (dl = value of a table column)

If this will involve hybrid coding, I prefer PL/perl.  The linux env has both "mail" and "mutt" (if this is of any help).  

The idea is to send a report to the list when all the data has been collected for a particular job and the final status of the job is updated as a col of a rec of a certain table.  Probably a post update trigger. 

I'd probably limit the trigger to checking for the completion of the data collection and inserting a record into a "email job" table.  Then I'd have cron on a linux machine periodically run a script that queries the "email job" table for work, perform the work, and then either flag the work as done or remove the job record.
