salut,

are cineva o functie care verifica IBAN-ul?

care este algoritmul...ceva ajutor?

multumesc mult.

 

alex.

Daca te uiti in Wikipedia, IBAN-urile pot avea diverse forme in functie de tara
http://en.wikipedia.org/wiki/IBAN
Are si checksum ...

eu m-am uitat aici

http://www.validari.ro/iban.htm

si mi se pare ca se poate face, asta e algoritmul.

deci, daca cineva poseda deja functia asta va rog sa mi-o dati si mie

multumesc.

 

alex.

am o problema,

dupa ce am convertit IBAN-ul adica l-am adus de forma 1010101011131007593840000272449 (cum spune in linkul de mai sus)

declare @var int
set @var = 1010101011131007593840000272449
select @var

primesc eroarea:

Arithmetic overflow error converting expression to data type int.

de ce timp trebuie sa fie acest numar ca sa-l pot imparti la 97.

multumesc.

alex.

chiar nu stiu cum sa impart la 97...cum sa convertesc ca sa pot face modulo (%)

are cineva vreo idee....

-- daca il puneti intr-un QA nu e cine stie ce o sa vedeti (am facut marea prostie sa impart IBAN-ul in 24 de caractere..asa am stiut eu sa convertesc fiecare bucatica din el)

multumesc.

Având în vedere că nu există în SQL Server un tip de date care să poată prelucra exact un număr având până la 48 de cifre (sau chiar 68, având în vedere că în alte ţări IBAN-ul poate avea până la 34 de caractere), va fi nevoie să îţi aminteşti cum se făcea împărţirea la clasa a 2-a şi să implementezi algoritmul respectiv. Eu am făcut acest lucru, dar nu în T-SQL, ci în alt limbaj.

Răzvan

chiar nu-mi dau seama cum ma poate ajuta impartirea de clasa a 2-a in situatia de fata :) ....imi poti da mai multe amanunte....multumesc.

@Alex: nu te supăra dar am impresia că eşti masochist.
Transformarea caracterelor în coduri se poate realiza folosind o funcţia (de exemplu):
CREATE FUNCTION Caracter2Cod( @c CHAR(1) )
RETURNS TINYINT
AS
BEGIN
  DECLARE @t TABLE (Caracter CHAR(1), Cod TINYINT)
  INSERT INTO @t VALUES ('A',10)
  INSERT INTO @t VALUES ('B',11)
  INSERT INTO @t VALUES ('C',12)
...
...
...
  RETURN (SELECT Cod FROM @t WHERE Caracter = @c)
END
Apel:
SELECT dbo.Caracter2Cod( 'B' )

Poţi simplifica implementarea funcţiei Caracter2Cod plecând de la codul ASCII al caracterului.

Pentru a calcula modulo folosind numere mari ai expuse aici două metode (atenţie la teste).
Exemplu: foloseşti formulele
n * m mod p = ((n mod p) * (m mod p)) mod p

n + m mod p = ((n mod p) + (m mod p)) mod p

1010101011131007593840000272449 => 101010101113100*10^LEN('7593840000272449') + 7593840000272449
1010101011131007593840000272449 => 101010101113100*10^16 + 7593840000272449
adică
((101010101113100*10^16 mod 97) + (7593840000272449 mod 97)) mod 97
Şi aici 101010101113100*10^16 mod 97 aplici n * m mod p = ((n mod p) * (m mod p)) mod p .

Referitor la IBAN

nu-i nici o problema...din ce e acolo se prea poate :)...in fine....tot nu-mi iese....nu-mi da rest 1 cum ar trebui...si nu inteleg de ce

le-am tot spart si degeaba...nu inteleg unde gresesc

mai jos e functia....si apoi selectul...daca are cineva timp sa arunce un ochi...poate isi da seama ce nu e corect acolo in ultima parte

multumesc.

Cam ăsta e algoritmul de împărţire de la clasa a 2-a (numai că atunci coborai doar câte o cifră, iar aici poţi să le iei câte 8).
