Najgori SQL query na svetu
 
Jos uvek ne mogu da poverujem u ovo sto sam video veceras. Mislim da covek koji napise ovakav query ne samo da treba da dobije otkaz nego jos i batine:

SELECT DISTINCT users.id, users.membership, (((acos(sin((35.7589*pi()/180)) * sin((users.latitude*pi()/180))+cos((35.7589*pi()/180)) * cos((users.latitude*pi()/180)) * cos(((-78.7798- users.longitude)*pi()/180))))*180/pi())*60*1.1515) as distance

Ovo sam dobio od coveka koji odrzava jedan server i koji kao i ja ne moze da se nacudi koji ludak moze ovo da napise. Hajde neko ako sme neka pusti ovaj query :)

bluesman 20. 03. 2008. 03:24
Da dodam da je ovo query koji se izvrsava na jako posecenom sajtu koji ima preko 6000 kverija u sekundi, i da dodam da su srbi autori ovog remek dela.

Evo sada kada gledam verovatno je to neki advanced search form pa trazi distance preko ZIP i longitude... + ima sliku, + nije obrisan + jos milion nekih stvari koje ni ne razumem... Ja bre kada imam vise od 3 JOIN-a po queriju - radim redesign baze, a ovo u zivotu nisam video... iskreno nisam ni znao da moze ovo :)

Sajt koristi 10 SQL servera i vlasnici ne mogu da se nacude kako hardware ne moze da pokrije zahtevnost :)

conica 20. 03. 2008. 03:36
evo ja cu da budem veoma iskrena, pa makar me nazvali neznalicom (:)): ja ovo ne bih UMELA da napisem
znaci totalno bih se zagubila kod treceg JOIN-a

edit: apropo, treba odati priznanje autoru..ovo je trebalo znati napisati

bluesman 20. 03. 2008. 03:45
To sam i ja rekao :)

Nego evo jos komentara administratora servera:

Citat:
inace, onaj kveri sam pustio na masteru pre vise od pola sata
i jos nije zavrsio
a master je ZVER
pazi, master ima 12 diskova u raid 10
16G rama
4 CPU-a
mislim, sta reci ;)
zver ;)
a ovo jos uvek traje ;)))
2600 sec i traje jos uvek
ne mogu vise da cekam, prekinucu ga :))))

Milos Vukotic 20. 03. 2008. 03:52
Off Topic: 'bem ti ovakvo radno vrijeme...

Pored svega ostalog, ovo je wtf samo za sebe:
users.gender = '4112'

Je li "gender" u smislu "pol"? Koliko ih moze biti? :)

conica 20. 03. 2008. 03:59
↑ LOL

Off Topic: a svaki put obecam sebi da cu leci pre 6

ppavlovic 20. 03. 2008. 04:26
Meni se dopada ono:

WHERE 1 AND users.gender = '4112'

P.S. Koji je kod generator koristio za ovako nesto ???

Mislim, kad sam pokusao da pravim jedan dating sajt, dosao samo do 5-6 joina ... i to se jaako sporo izvrsavalo. Pa sam onda zaboravio na normalizacije koje te uce u skoli. I sve je bilo kako treba. :)

twix 20. 03. 2008. 08:27
Cemu ovo sluzi a uz to i ne radi :1064: salim se, da li moze da se vidi sajt koji u pozadini mrsi ovaj sql ?

Aleksandar.Ilic 20. 03. 2008. 10:02
i jos ako nesto ovde nije indexirano :O

bofh 20. 03. 2008. 10:14
upit je u svakom slučaju skandalozan i lolkastičan.

ono što je meni skoro jednako skandalozno što se nigde ne primećuje opasno brkanje lončića.

sysadmin != dba != web developer

i da, btw, glupost je univerzalna stvar, tako da to nema veze sa srbima... ko se usprotivi tome proglasiću ga za izdajnilka lol
