Обсуждение: Email and Postgres

Hi all,
Does anyone know if you can send email using pgsql and triggers or some
other way?
Thanks

I don't think so (when I looked anyway), but I hacked the PHP mail
function and compiled it as a user function... It doesn't do any checking
(never got around to it) but it works.  Someday I'll do that...

The first comment is what I used to compiled it... you'll need to tweak
some of the options to point to the right place.  I don't remember the
exact syntax to add it to the database, but it's in the manual and was
easy...  you might also needto change the path to sendmail...

    if( fd )  {
        fprintf(fd, "From: %s\n", textout(from));

        fprintf(fd, "Subject: %s\n", textout(subject));
        fprintf(fd, "\n");
        fprintf(fd, "%s", textout(body));

        success = pclose(fd);
    }else {
        success = 0;
    }

    return(success);
}

Some other way:  I don't use triggers much.  My interface does the
work...so:

I have perl do it.  Using the binding operator ( =~ ) I search a
text str for a regex.  If found the perl script looks up a list of
addresses in a db relation and sends them mail.   If you want a
look at my src say the word.

Hmm...thinking on this abit:  you could insert into a table (named
shell or whatever) a unix command.  Then, when your expr evals to
true you could do a system() call...at least in C or perl...
just thinking aloud!

Good hunting,
Tom
