OdbcTransaction Class

Represents an SQL transaction to be made at a data source. This class cannot be inherited.

Namespace:  System.Data.Odbc
Assembly:  System.Data (in System.Data.dll)

Public NotInheritable Class OdbcTransaction _
	Inherits DbTransaction

The OdbcTransaction type exposes the following members.

Public propertyConnectionGets the OdbcConnection object associated with the transaction, or Nothing if the transaction is no longer valid.
Public propertyIsolationLevelSpecifies the IsolationLevel for this transaction. (Overrides DbTransaction.IsolationLevel.)

Public methodCommitCommits the database transaction. (Overrides DbTransaction.Commit.)
Public methodCreateObjRefCreates an object that contains all the relevant information required to generate a proxy used to communicate with a remote object. (Inherited from MarshalByRefObject.)
Public methodDisposeReleases the unmanaged resources used by the DbTransaction. (Inherited from DbTransaction.)
Public methodEquals(Object)Determines whether the specified object is equal to the current object. (Inherited from Object.)
Public methodGetHashCodeServes as the default hash function. (Inherited from Object.)
Public methodGetLifetimeServiceRetrieves the current lifetime service object that controls the lifetime policy for this instance. (Inherited from MarshalByRefObject.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodInitializeLifetimeServiceObtains a lifetime service object to control the lifetime policy for this instance. (Inherited from MarshalByRefObject.)
Public methodRollbackRolls back a transaction from a pending state. (Overrides DbTransaction.Rollback.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

Explicit interface implemetationPrivate propertyIDbTransaction.ConnectionGets the DbConnection object associated with the transaction, or a null reference if the transaction is no longer valid. (Inherited from DbTransaction.)

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

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

Public Sub ExecuteTransaction(ByVal connectionString As String)

    Using connection As New OdbcConnection(connectionString)
        Dim command As New OdbcCommand()
        Dim transaction As OdbcTransaction

        ' Set the Connection to the new OdbcConnection.
        command.Connection = connection

        ' Open the connection and execute the transaction. 

            ' Start a local transaction.
            transaction = connection.BeginTransaction()

            ' Assign transaction object for a pending local transaction.
            command.Connection = connection
            command.Transaction = transaction

            ' Execute the commands.
            command.CommandText = _
                "Insert into Region (RegionID, RegionDescription) VALUES (100, 'Description')"
            command.CommandText = _
                "Insert into Region (RegionID, RegionDescription) VALUES (101, 'Description')"

            ' Commit the transaction.
            Console.WriteLine("Both records are written to database.")

        Catch ex As Exception
            ' Try to rollback the transaction 

                ' Do nothing here; transaction is not active. 
            End Try 
        End Try 
        ' The connection is automatically closed when the 
        ' code exits the Using block. 
    End Using 
End Sub
