IDbTransaction Interface

 

Represents a transaction to be performed at a data source, and is implemented by .NET Framework data providers that access relational databases.

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

type IDbTransaction = 
    interface
        interface IDisposable
    end

NameDescription
System_CAPS_pubpropertyConnection

Specifies the Connection object to associate with the transaction.

System_CAPS_pubpropertyIsolationLevel

Specifies the IsolationLevel for this transaction.

NameDescription
System_CAPS_pubmethodCommit()

Commits the database transaction.

System_CAPS_pubmethodDispose()

Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.(Inherited from IDisposable.)

System_CAPS_pubmethodRollback()

Rolls back a transaction from a pending state.

The IDbTransaction interface allows an inheriting class to implement a Transaction class, which represents the transaction to be performed at a data source. For more information about Transaction classes, see Transactions and Concurrency.

An application does not create an instance of the IDbTransaction interface directly, but creates an instance of a class that inherits IDbTransaction.

Classes that inherit IDbTransaction must implement the inherited members, and typically define additional members to add provider-specific functionality. For example, the IDbTransaction interface defines the Commit method. In turn, the OleDbTransaction class inherits this property, and also defines the Begin method.

Notes to Implementers:

To promote consistency among .NET Framework data providers, name the inheriting class in the form Prv Transaction where Prv is the uniform prefix given to all classes in a specific .NET Framework data provider namespace. For example, Sql is the prefix of the SqlTransaction class in the System.Data.SqlClient namespace.

The following example creates instances of the derived classes, SqlConnection and SqlTransaction. It also demonstrates how to use the BeginTransaction, Commit, and Rollback methods.
