ERROR：クエリに結果データの宛先がありませんDove：PL/pgSQL関数VOID

Question

皆さん、こんにちは私はPostgreSQLでこの関数に問題があり、PostgreSQL言語を使用する必要があります。 ように、コードはこれです：私はエラーを取得する

SELECT fnc_richiesta_attivazione_out_update_cdo(39, 'qqqqqqqq', '2016-08-03 23:00:00'); 

：

[42601] ERROR: query has no destination for result data Dove: PL/pgSQL function fnc_richiesta_attivazione_out_update_cdo(integer,character varying,timestamp without time zone) line 22 at SQL statement.

私はエラーを解決するが、私は実行する場合はすることはできません

CREATE OR REPLACE FUNCTION public.fnc_richiesta_attivazione_out_update_cdo(olo_rec_id INTEGER, current_uuid VARCHAR, requested_dco_date TIMESTAMP) 
RETURNS VOID 
AS 
$$ 
DECLARE 
    flag_no_pah VARCHAR := 'N'; 
    time_threshold INTEGER := 300; 
    rda_inserted_status INTEGER := 14; 
    invalid_status VARCHAR := 'N'; 
    last_time_requested INTEGER; 
    limit_rows INTEGER; 
    n_richieste INTEGER; 
    capacita_max INTEGER; 
    c_requests INTEGER; 
    codice_olo_rec VARCHAR; 
    num_max_req VARCHAR:= 'NUM_MAX_RICHIESTE_PER_FILE'; 

BEGIN 
    SELECT valore INTO limit_rows FROM configurazione WHERE chiave = num_max_req; 
    SELECT num_richieste INTO n_richieste FROM conta_rda_inv WHERE olo = olo_rec_id; 
    SELECT codice_olo_amm INTO codice_olo_rec FROM configurazione_olo WHERE id = olo_rec_id; 
    SELECT EXTRACT(EPOCH FROM (current_date - (SELECT ora_ultimo_invio FROM conta_rda_inv WHERE olo = olo_rec_id))) INTO last_time_requested; 
    SELECT COUNT(id_richiesta) INTO c_requests FROM richieste WHERE id_lock = current_uuid; 

    UPDATE richieste SET id_lock = current_uuid, data_cut_over_richiesta = requested_dco_date WHERE id_richiesta IN (
     SELECT id_richiesta 
     FROM richieste 
     WHERE id_lock IS NULL AND 
      codice_op_rec = codice_olo_rec AND 
        id_richiesta_stati = rda_inserted_status AND 
        flag_pah = flag_no_pah AND 
        (valido IS NULL OR valido <> invalid_status) 
     ORDER BY ts_ins ASC 
     LIMIT limit_rows 
    --) RETURNING *; 
    ); 

    IF (n_richieste > capacita_max*2) THEN 
     UPDATE richieste SET id_lock = NULL WHERE id_lock = current_uuid; 
    ELSIF (c_requests < limit_rows AND last_time_requested < time_threshold) THEN 
     UPDATE richieste SET id_lock = NULL WHERE id_lock = current_uuid; 
    END IF; 
END 
$$ 
LANGUAGE plpgsql VOLATILE; 

そして、ときに私が実行単一のSELECTが機能する

この関数にパラメータ1を使用すると、問題が発生します。例 SELECT fnc_richiesta_attivazione_out_update_cdo（39、 'qqqqqqqq'、 '2016-08-03 23:00:00'）;
