SSIS DTS Task Script обнаружил исключение в пользовательском коде

Question

Я пытаюсь выполнить пакет SSIS с компонентом сценариев в Visual Basic 2010. Я получаю следующее сообщение об ошибке, когда я исполняю пакет:

public void Main() 
    { 
     // TODO: Custom Code starts here 
     /* 
     * Description: Reads the input CMI Stats files and converts into a more readable format

     * Here is the description from original procedure 
     * CustType = DOMESTIC/INTERNATIONAL/ETC 
     * CategoryType = SBU/MAN

     Failure = Microsoft.SqlServer.Dts.Runtime.DTSExecResult.Failure

    #endregion 

} 

}

Можно ли предположить, что могло бы, возможно, пошло не так, или, может быть, как отладить этот код, чтобы понять ошибки?

Спасибо!

Answer 1

Вот как отлаживать скрипты в SSIS

• С кодом открытым, поставить точку останова
• Закрыть код
• Запустите пакет
• Когда скрипт запускается, он откроется кода и вы можете пройти через код шаг за шагом
