icon Da li je paradox relaciona baza?12.04.2004. u 02:01 - pre 213 meseci
Probao sam napraviti u Databasedesktopu da povezem tri baze: Ulaz, Stavka Ulaza, Dobavljac. Prvo na StavkaUlaza definisem referential integrity i spojim je sa bazom Ulaz preko dva polja (vidi se na semi dole). Onda definisem referencu na bazi Ulaz i spojim je sa Dobavljacem. Medjutim kad krenem da snimim bazu Ulaza on kaze da je Ulaz.db los fajl. Pokusao sam i SaveAs i novu bazu ali nece. Da li je problem do Databasedesktopa? Moze li se to izvesti u kodu bez rada u Databasedesktopu? Da li paradox uoste moze da podrzi referential integrity na vise od dvije baze?  
Sema baza bi bila sljedeca...
