Re: ALTER in procedure

23 Jul 2013

      I'm really sorry for the mistake. Indeed it works the same now both 
procedure and plain SQL.
I'm going to keep looking around ...

Thank you for your help.

Did you try to compare *the same* query between plain SQL and in procedure?
Mind in particular
SELECT COUNT(DISTINCT p.cislo_karty)
vs.
SELECT DISTINCT p.cislo_karty
(and I assume you use the same data and same timestampes in both/all cases)
If both of the above are fast in plain SQL but slow in a procedure,
you might want to use stethoscope [1] to find out where things hang.

Hi,
I looks like different kind of issue. I'm running into problem when
almost the same SQL running separately takes 5 seconds and in a
procedure it never finishes (30 minutes ...).
Following insert takes 5 seconds:
INSERT INTO crmkartastitek (
        cislo_karty,
        stitek_id,
        stitek_nazev,
        stitek_upresneni
       )
SELECT COUNT(DISTINCT p.cislo_karty),120,'sdfgdf','sdfgsdf'
       FROM crmkartaaktivita k
       JOIN crmkartapohyby p ON p.cislo_karty=k.cislo_karty
       WHERE 1=1
         AND k.aktivita > 0
         AND p.pohyb = 'VV'
         AND p.datum BETWEEN (timestamp'2013-07-01 00:00:00' - INTERVAL
'12' MONTH) AND (timestamp'2013-07-01 00:00:00' - INTERVAL '1' DAY)
Following procedure never returns:
DROP PROCEDURE crm_segm_kvv_rl
/
-- vyhodnotí pravidlo pro štítek KKV
-- @param p_interval dle číselníku crmregstitek
-- @param p_datum timestamp, první den v měsíci, např. timestamp
'2013-07-01 00:00:00'
CREATE PROCEDURE crm_segm_kvv_rl(p_interval INT, p_datum timestamp)
-- $Id: crm_segm_kvv_rl.sql 958 2013-07-22 08:40:30Z rbiciste $
BEGIN
    -- hlavička procedury
    DECLARE v_proc VARCHAR(250);
    SET v_proc = 'crm_segm_kvv_rl';
    -- nastav id pravidla
    DECLARE v_stitek_id int;
    DECLARE v_stitek_nazev,v_stitek_upresneni VARCHAR(200);
    -- nastav štítek
    SET v_stitek_id = 100;
    SELECT nazev,upresneni INTO v_stitek_nazev,v_stitek_upresneni FROM
crmregstitek WHERE stitek_id = v_stitek_id;
    -- proveď výpočet pouze pokud spouštím měsíční přepočet
    IF p_interval = crm_segm_vrat_spusteni(v_stitek_id) THEN
      INSERT INTO crmkartastitek (
        cislo_karty,
        stitek_id,
        stitek_nazev,
        stitek_upresneni
       )
       SELECT DISTINCT
p.cislo_karty,v_stitek_id,v_stitek_nazev,v_stitek_upresneni
       FROM crmkartaaktivita k
       JOIN crmkartapohyby p ON p.cislo_karty=k.cislo_karty
       WHERE 1=1
         AND k.aktivita > 0
         AND p.pohyb = 'VV'
         AND p.datum BETWEEN (p_datum - INTERVAL '12' MONTH) AND (p_datum
- INTERVAL '1' DAY);
    END IF;
END;
/
-- tests
call crm_segm_kvv_rl(1,timestamp '2013-07-01 00:00:00')
/
I tried:
1) comment out IF
2) replace variables v_xxx for constants like 'dfghdfgh' etc
Maybe I'm trying to do things Oracle way... but have not learned the
monet way yet.
Thank you,
Radovan
