Обсуждение: create function syntax error

Hello

I Always get "syntax error" for every function that I try to create, for
example:
    mydb'>create or replace function f_sum () returns void as '
    mydb'> select 2+2;
    mydb'>  ' LANGUAGE plpgsql;
    ERROR:  syntax error at or near "select" at character 56
    LINE 2: select 2+2;
        ^

What its the problem ??
   Thank you,
         Gustavo

Several:
- wrong quotation, either with '' or with dollar-quote
- no 'begin'
- no 'end;'

Please read the docu:
http://www.postgresql.org/docs/8.1/interactive/plpgsql.html

There are many examples, for instance:

You are missing the BEGIN and END section. Make your function like this:

CREATE OR REPLACE FUNCTION f_sum() RETURNS void AS '
BEGIN
   select 2+2;
END;
' LANGUAGE plpgsql;

Uhm, sorry. Error from me. The single quote after the 'as' is oray.
