[GENERAL] SQL function and input variables

[Martín Marqués]

I was makeing an SQL function and got an error which on a sintax that
I thouhgt would work:

CREATE OR REPLACE FUNCTION dicInsertarPalabra(p TEXT)
RETURNS INT AS $body$
        INSERT INTO public.diccionario (palabra) VALUES (quote_literal(p));
        SELECT COALESCE(codigo,0) FROM public.diccionario
               WHERE palabra = quote_literal(p);
$body$ LANGUAGE 'SQL';

Changing p for $1 in the body of the function makes it work. But,
can't we label input arguments like how I did here?
