    OracleTransaction Class
    In This Topic
    Represents a SQL transaction to be made in the Oracle database.
    Syntax
    'Declaration
     
    Public Class OracleTransaction 
       Inherits Devart.Common.DbTransactionBase
       Implements System.Data.IDbTransactionSystem.IDisposable 
    Remarks

    The application creates a OracleTransaction object by calling OracleConnection.BeginTransaction on the OracleConnection object. All subsequent operations associated with the transaction (for example, committing or aborting the transaction), are performed on the OracleTransaction object.

    The correlation between OracleConnection and OracleTransaction is always 1:1.

    Example
    The following example creates a OracleConnection and a OracleTransaction. It also demonstrates how to use the OracleConnection.BeginTransaction, Commit, and Rollback methods.
    public static void RunOracleTransaction(string myConnString) {
            using (OracleConnection myConnection = new OracleConnection(myConnString)) {
                    myConnection.Open();
                    // Start a local transaction
                    OracleTransaction myTrans = myConnection.BeginTransaction(System.Data.IsolationLevel.ReadCommitted);
                    OracleCommand myCommand = myConnection.CreateCommand();
                    try {
                            myCommand.CommandText = "INSERT INTO Dept(DeptNo, DName) Values(52, 'DEVELOPMENT')";
                            myCommand.ExecuteNonQuery();
                            myCommand.CommandText = "INSERT INTO Dept(DeptNo, DName) Values(62, 'PRODUCTION')";
                            myCommand.ExecuteNonQuery();
                            myTrans.Commit();
                            Console.WriteLine("Both records are written to database.");
                    }
                    catch (Exception e) {
                            myTrans.Rollback();
                            Console.WriteLine(e.ToString());
                            Console.WriteLine("Neither record was written to database.");
                    }
                    finally {
                            myCommand.Dispose();
                            myTrans.Dispose();
                    }
