OracleTransaction Class

Represents a transaction to be made in the database.

Namespace: System.Data.OracleClient
Assembly: System.Data.OracleClient (in system.data.oracleclient.dll)

public sealed class OracleTransaction : DbTransaction
public final class OracleTransaction extends DbTransaction
public final class OracleTransaction extends DbTransaction

The application creates an OracleTransaction object by calling 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 following example creates an OracleConnection and an OracleTransaction. It also demonstrates how to use the BeginTransaction, Commit, and Rollback methods.

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.");
