Examples

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

C#
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.");
        }
    }
}

Remarks

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.

Properties

Connection

Specifies the OracleConnection object associated with the transaction.

DbConnection

When overridden in a derived class, gets the DbConnection object associated with the transaction.

(Inherited from DbTransaction)
IsolationLevel

Specifies the IsolationLevel for this transaction.

Methods

Commit()

Commits the SQL database transaction.

CreateObjRef(Type)

Creates an object that contains all the relevant information required to generate a proxy used to communicate with a remote object.

(Inherited from MarshalByRefObject)
Dispose()

Releases the resources used by this object.

Dispose()

Releases the unmanaged resources used by the DbTransaction.

(Inherited from DbTransaction)
Dispose(Boolean)

Releases the unmanaged resources used by the DbTransaction and optionally releases the managed resources.

(Inherited from DbTransaction)
Equals(Object)

Determines whether the specified object is equal to the current object.

(Inherited from Object)
GetHashCode()

Serves as the default hash function.

(Inherited from Object)
GetLifetimeService()
Obsolete.

Retrieves the current lifetime service object that controls the lifetime policy for this instance.

(Inherited from MarshalByRefObject)
GetType()

Gets the Type of the current instance.

(Inherited from Object)
InitializeLifetimeService()
Obsolete.

Obtains a lifetime service object to control the lifetime policy for this instance.

(Inherited from MarshalByRefObject)
MemberwiseClone()

Creates a shallow copy of the current Object.

(Inherited from Object)
MemberwiseClone(Boolean)

Creates a shallow copy of the current MarshalByRefObject object.

(Inherited from MarshalByRefObject)
Rollback()

Rolls back a transaction from a pending state.

ToString()

Returns a string that represents the current object.

(Inherited from Object)

Explicit Interface Implementations

IDbTransaction.Connection

Gets the DbConnection object associated with the transaction, or a null reference if the transaction is no longer valid.
