Обсуждение: Trigger and Trigger function, Part 2

Thanks for the assistance Michael Fuhr and Dr. DeSoi. The recoded function is much more what I wanted to anyway - one
genericfunction that could be used on multiple tables through their respective triggers. The new function I am trying
is:

  CREATE FUNCTION
  oc.upd_last_touch()
  RETURNS TRIGGER AS
  $upd_last_touch$
  BEGIN
    NEW.last_touch := current_timestamp;
    RETURN NEW;
  END;
  $upd_last_touch$
  LANGUAGE 'plpgsql' VOLATILE;

However, PostgreSQL is STILL giving me a syntex error on line two of the above function. The exact text is:

  ERROR: syntax error at or near "FUNCTION" at character 16.

This error gives me nightmares of QBasic from 1982. Syntex error indeed. I have included a screenshot from pgAdmin III
toshow you. This is why I am so stumped - the samples from the documentation do not work for me. Could this be an
installationor configuration issue? Does anyone see why this is not working for me?

I created an oc schema and used psql to copy the above code into a
database with no problems.  Have you tried using psql instead of
pgAdmin III?

In the image you attached, there's a marker on the left side of the
line that contains oc.upd_last_touch(), and it looks like the cursor
is just after the dot.  Are those significant, perhaps showing where
the problem is?  I don't use pgAdmin III -- does it have trouble
with schema-qualified function names?  What happens if you omit
"oc." and make the function name simply upd_last_touch?

The function as written works for me. I don't think it is a missing
schema error because in that case you would see a different error. My
best guess is there is some kind of invisible bad character there. Try
this: put the cursor in front of 'oc.' and backspace until it is next
to 'FUNCTION'. Then hit one space and try again.
