SQL Server 2008, ISIN Функция проверки
Это один проверяет формат с ISIN . Это расширяется код SQL, используя документацию по статье Википедии по ссылке. Вам нужно будет создать следующую таблицу, чтобы держать всю информацию в стране.
Это часть из трех связанных статей, которые будут проверять ISIN, SEDOL и Cusip идентификаторов.
