what's going on...

Hello!

I was trying to create a function:

CREATE FUNCTION analizuj_pomiary() RETURNS bool AS '
DECLARE pomiary RECORD;
BEGIN
FOR pomiary IN SELECT * FROM brewan_pomiar LOOP

IF substr(pomiary.datetime,1,10)=to_char(now(),'mm/dd/yyyy')
THEN
INSERT INTO TESTOWA
VALUES (
analizuj_flow(
pomiary.ipRouter,
pomiary.source_ip,
pomiary.dest_ip,
pomiary.bytes,
pomiary.datetime)
);
END IF;

END LOOP;
RETURN true;
END; ' LANGUAGE 'plpgsql';

... and I received an error:

ERROR: parser: parse error at or near "mm"

What's going on? What does it mean?
