A quick look at the docs didn't gave me any clue as to the way to tell
the function it must look at the column 'parola' for string
substitution.
See what happens:
Table "public.parole"
Column | Type | Modifiers
--------+---------+-----------
id | integer |
parola | text | not null
id | parola
----+----------
4 | humanité
5 | café
(2 rows)
CREATE FUNCTION unaccent(text) RETURNS text AS '
BEGIN
RETURN translate(&parola, "\342\347\350\351\352\364\373", "aceeeou");
^^^^^^^
END;
' LANGUAGE plpgsql IMMUTABLE STRICT;
^^^^ [I also tried with field, &field, parola, (parola), [parameter
"&field?"], $1, arg1 and similar]
# And this is what I get when I give the command:
non_acc=> select * from parole where unaccent(parola)='cafe';
ERROR: column "parola" does not exist ----------> ???????????????
CONTEXT: PL/pgSQL function "unaccent" line 2 at return
------------------------
Am I missing something important or that type of function is not
supposed to work in 7.4.7-2?

Ennio.
