{
OracleConnection myConnection = new OracleConnection(myConnString);
myConnection.Open();
OracleCommand myCommand = new OracleCommand();
myConnection.BeginTransaction();
try
{
myCommand.CommandText = "INSERT INTO Test.Dept(DeptNo, DName) Values(50, 'DEVELOPMENT')";
myCommand.ExecuteNonQuery();
myCommand.CommandText = "INSERT INTO Test.Dept(DeptNo, DName) Values(60, 'PRODUCTION')";
myCommand.ExecuteNonQuery();
myConnection.Commit();
Console.WriteLine("Both records are written to database.");
}
catch(Exception e)
{
myConnection.Rollback();
Console.WriteLine(e.ToString());
Console.WriteLine("Neither record was written to database.");
}
finally
{
myConnection.Close();
}
}
Public Sub RunOracleTransaction(myConnString As String)
Dim myConnection As New OracleConnection(myConnString)
myConnection.Open()
Dim myCommand As New OracleCommand()
myConnection.BeginTransaction()
Try
myCommand.CommandText = "INSERT INTO Test.Dept(DeptNo, DName) Values(50, 'DEVELOPMENT')"
myCommand.ExecuteNonQuery()
myCommand.CommandText = "INSERT INTO Test.Dept(DeptNo, DName) Values(60, 'PRODUCTION')"
myCommand.ExecuteNonQuery()
myConnection.Commit()
Console.WriteLine("Both records are written to database.")
Catch e As Exception
myConnection.Rollback()
Console.WriteLine(e.ToString())
Console.WriteLine("Neither record was written to database.")
Finally
myConnection.Close()
End Try
