Voorbeelden

In het volgende voorbeeld wordt een OracleConnection en een OracleTransaction. Het laat ook zien hoe u de BeginTransaction, Commiten Rollback methoden gebruikt.

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
        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 e As Exception
            transaction.Rollback()
            Console.WriteLine(e.ToString())
            Console.WriteLine("Neither record was written to database.")
        End Try
    End Using
End Sub

Opmerkingen

De toepassing maakt een OracleTransaction object door het BeginTransaction object aan te roepenOracleConnection. Alle volgende bewerkingen die zijn gekoppeld aan de transactie (bijvoorbeeld het doorvoeren of afbreken van de transactie), worden uitgevoerd op het OracleTransaction object.
