Question

使用以下方法，我可以使用ADO.NET对Oracle数据库运行事务。当我在SQL Server数据库上尝试相同的代码时，我收到错误。造成这种情况的原因是什么以及如何解决？

错误：

ExecuteNonQuery需要命令才能拥有事务分配给该命令的连接位于挂起的本地事务中。该命令的Transaction属性尚未初始化。

守则：

    /// <summary>
    /// A method to run transactional SQL on a database. Does not return a record set.
    /// </summary>
    /// <param name="transactions">A list of commands</param>
    /// <returns>A boolean indicator of success</returns>
    public bool ExecuteTransactionNonQuery(List<string> transactions)
    {
        if (transactions == null)
        {
            throw new ArgumentNullException("transactions");
        }

        PrepareConnection();

        DbTransaction dbTransaction = DBFactoryDatabaseConnection.BeginTransaction();

        try
        {
            foreach (var transaction in transactions)
            {

                DBFactoryDatabaseCommand.CommandText = transaction;
                DBFactoryDatabaseCommand.CommandType = CommandType.Text;
                DBFactoryDatabaseCommand.ExecuteNonQuery();
            }

            dbTransaction.Commit();
        }
        catch(Exception ex)
        {
            dbTransaction.Rollback();
            try
            {
                Close();
            }
            catch (Exception f)
            {
                throw new Exception("Error: Transaction execute failed on the database. " + ex.Message + ". Following that the application failed to close the connection. " + f.Message + ". ExecuteTransactionNonQuery().");
            }
            throw;
        }
        finally
        {
            dbTransaction.Dispose();
        }

        return true;
    }

您需要将交易分配给命令。

DBFactoryDatabaseCommand.Transaction = dbTransaction;
