trigger to run external script
Chau, Artemis <artemis.chau@intel.com> — 2000-09-26T18:26:17Z
All, I want to have a trigger for a table that whenever a new record is created to run an external shell script on Unix. Any suggestion? -- Artemis

I do this - but my IF is perl. When the user INSERTs INTO a table (without error) my script generates email to any interested parties. If the user makes an error my script dumps detailed info (including username) into a log file. If you want to do something similar, it is relatively easy via shell script or perl...presumably in any interface really. So the issue is only: do your users enter data from a psql sh prompt or from an IF? If they use psql then you could define a trigger that makes an entry into a second table... -------------------------------------------------------------------- SVCMC - Center for Behavioral Health -------------------------------------------------------------------- Thomas Good tomg@ { admin | q8 } .nrnet.org IS Coordinator / DBA Phone: 718-354-5528 Fax: 718-354-5056 -------------------------------------------------------------------- Powered by: PostgreSQL s l a c k w a r e FreeBSD: RDBMS |---------- linux The Power To Serve -------------------------------------------------------------------- -

I also would be interested in having a trigger run a shell or python script, but didn't really see anything in the documentation that indicated how to go about this. I would appreciate any pointers on where to go for more info. Basically, I run a dialup server which logs uploads to a PostGres table. I would like the logging of an upload "trigger" an external program that further processes the uploaded file based on the uploader information. TIA
