DELETE ne radi

[erbi]

Imam jedan kod:

Kod [Odaberi] Expand


$result = mysqli_query($con,"select *
FROM xlpix_votes
    INNER JOIN (
        SELECT MAX(ip) AS lastIp, option_id, date, MAX(id) as maxId
        FROM xlpix__votes
        GROUP BY ip, DATE_FORMAT(DATE(xlpix_votes.date), '%Y-%m-%d')
        HAVING COUNT(*) > 1
    ) duplicate ON duplicate.lastIp = xlpix_votes.ip
where DATE_FORMAT(DATE(xlpix_votes.date), '%Y-%m-%d') = DATE_FORMAT(DATE(duplicate.date), '%Y-%m-%d')
AND maxId > xlpix_votes.id
AND xlpix_votes.ip != 123");

Ovaj kod mi ispravno pokazuje sve duplikate, a ako na početku umjesto SELECT * stavim DELETE, neče da obriše ove duplikate.

Pa gdje je greška?

[Dario]

A greška koja se ispiše je... ?

Pozdrav Dario ...
Ništa, potpuno prazan monitor

[Dario]

Ajd mi molim te eksportiraj te tablice iz query-ja pa mi ih zakači ovdje u attachment da ja to poledam malo bolje :)

[erbi]

Evo u privitku.
Nešto sam mislio, da ne bi radio delete, več update option_id sa večanjem vrijednosti option_id + 1000. Ako ima sada 50, onda bi bio option_id 1050. Ovo bi bilo puno bolje

Za brisanje bi ispravan query bio

DELETE FROM xlpix_acepolls_votes WHERE id IN (

SELECT id FROM xlpix_acepolls_votes

FROM xlpix_acepolls_votes
GROUP BY ip, DATE_FORMAT(DATE(xlpix_acepolls_votes.date), '%Y-%m-%d')

Update/Delete nemože radit samo tako ko select ako radiš oboje na istoj tablici....

Uglavnom za update ti je isti princip samo radiš update umjesto delete...

[erbi]

hm, nešto mi ne radi ..
Parse error: syntax error, unexpected 'FROM' (T_STRING) in .....

[Dario]

A neznam kaj da ti velim... ja sam testirao s SQL-om koji si mi dao i sad sam s foruma kopirao query (za svaki slucaj)...

[erbi]

Onda sm ja zabrkljao ... ja sam ovo sa php ne phpmyadmin  ???

[erbi]

Hvala Dario..
Se izvinjavam... Na kraju zaboravio "

[Dario]

heheh, bitno da radi :)
