DatabaseSchemaUpdater.AddColumn(Of T) Method

[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]

Adds a database column to a local database.

Namespace:  Microsoft.Phone.Data.Linq
Assembly:  System.Data.Linq (in System.Data.Linq.dll)

'Declaration
Public Sub AddColumn(Of T) ( _
	columnPropertyName As String _
)

Type Parameters

T

The entity type corresponding to the applicable database table.

Parameters

columnPropertyName
Type: System.String
The name of the column in the corresponding data context.

The database does not change to reflect updates from the DatabaseSchemaUpdater object until the Execute method is called. When that method is called, all changes are submitted to the local database as a single transaction, including version updates. Using a single transaction helps the database maintain integrity, such as in cases where the user exits the application during an upgrade.

For information about using a local database in your Windows Phone application, see Local database for Windows Phone 8.
