예제

다음 예제에서는 및 를 OracleConnectionOracleTransaction만듭니다. 사용 하는 방법을 보여 줍니다 합니다 BeginTransaction, Commit, 및 Rollback 메서드.

public void RunOracleTransaction(string connectionString)
{
    using (OracleConnection connection = new OracleConnection(connectionString))
    {
        connection.Open();

        OracleCommand command = connection.CreateCommand();
        OracleTransaction transaction;

        // Start a local transaction
        transaction = connection.BeginTransaction(IsolationLevel.ReadCommitted);
        // Assign transaction object for a pending local transaction
        command.Transaction = transaction;

        try
        {
            command.CommandText =
                "INSERT INTO Dept (DeptNo, Dname, Loc) values (50, 'TECHNOLOGY', 'DENVER')";
            command.ExecuteNonQuery();
            command.CommandText =
                "INSERT INTO Dept (DeptNo, Dname, Loc) values (60, 'ENGINEERING', 'KANSAS CITY')";
            command.ExecuteNonQuery();
            transaction.Commit();
            Console.WriteLine("Both records are written to database.");
        }
        catch (Exception e)
        {
            transaction.Rollback();
            Console.WriteLine(e.ToString());
            Console.WriteLine("Neither record was written to database.");
        }
    }
}

Public Sub RunOracleTransaction(ByVal connectionString As String)
    Using connection As New OracleConnection(connectionString)
        connection.Open()

        Dim command As OracleCommand = connection.CreateCommand()
        Dim transaction As OracleTransaction

        ' Start a local transaction

        ' Assign transaction object for a pending local transaction
        command.Transaction = transaction

        Try

            transaction.Commit()
            Console.WriteLine("Both records are written to database.")
        Catch e As Exception
            transaction.Rollback()
            Console.WriteLine(e.ToString())
            Console.WriteLine("Neither record was written to database.")
        End Try
