Обсуждение: PL/pgSQL Syntax Problem

Hi,

this function:

CREATE FUNCTION t_nummern(integer) -- Parameter: lfd_nr
RETURNS text AS '
  DECLARE
    lfd_nr ALIAS FOR $1;
    erg text;
    daten record;
  BEGIN
    erg := '''';
    FOR daten IN
      SELECT * INTO daten FROM telefon WHERE t_lfd_nr = lfd_nr
    LOOP
      IF erg <> '''' THEN
        erg := erg || '', '';
      END IF;
      IF daten.t_einrichtg <> '''' THEN
        erg := erg || daten.t_einrichtg || '': '';
      END IF;
      erg := erg || ''('' || daten.vorwahl || '') '' || daten.telefon_nr;
    END LOOP;
    RETURN erg;
  END;'
LANGUAGE 'plpgsql';

causes the following error:

mitglieder=> select t_nummern(330);
ERROR:  query "SELECT  * INTO daten FROM telefon WHERE t_lfd_nr =  $1 "
isn't a
SELECT
mitglieder=>

Why isn't this a SELECT??

Thanks in advance,

when using a for loop you don't need the into, eg.

FOR daten IN SELECT * FROM telefon WHERE t_lfd_nr = lfd_nr

each row will be placed in daten.
