Обсуждение: Problems w/ PL/pgSQL not being loaded?
Hi all. Once again, I'm trying to climb the learning curve... I'm trying to write a trigger in PL/pgSQL to update some tables. When I try to load the function, I get an error message: The function is: create function update_modified () returns opauqe as ' BEGIN NEW.modified := ''now()''; return 1; END; ' language 'plpgsql'; The error message indicates that I'm trying to us an unrecognized language. The recognized languages are sql, C, internal and other created languages. I've not loaded anything besides the default. 1. How do I load PL/pgSQL? 2. Does this function look right? It should change the a.modified field upon update. Thanx again, Mike Diehl, Network Monitoring Tool Devl. 284-3137 jdiehl@sandia.gov
I just did this in 7.1 (and I think it's pretty similar in 7.0.x). cd into the src/pl/plpgsql directory and type "gmake && gmake install" Then as the postgres super user type "createlang plpgsql dbname" where "dbname" is the name of the database you want to add it to. If you add it to template1 then all new databases will automatically get it. good luck! -philip On Tue, 17 Apr 2001, Diehl, Jeffrey wrote: > Hi all. > > Once again, I'm trying to climb the learning curve... > > I'm trying to write a trigger in PL/pgSQL to update some tables.

Yup. Took me all of 15 minutes to do this and test it.
