Database, Using Transaction

Problem

You need to issue multiple database updates in the context of a single, atomic transaction.

Solution

Use an ADO.NET transaction to envelop the various SQL statements that need to be processed as a unit.

Discussion

The following block of code connects to a database via ADO.NET and makes several database updates within a single transaction:

' ----- Connect to the database.
 Dim connectionString As String = _
    "Data Source=MySystem\SQLEXPRESS;" & _
    "Initial Catalog=MyDatabase;Integrated Security=true"
 Dim theDatabase As New SqlClient.SqlConnection(connectionString)
 theDatabase.Open( )

 ' ----- Create a command object that will hold each
 '       processed SQL statement.
 Dim sqlStatement As New SqlClient.SqlCommand
 sqlStatement.Connection = theDatabase
