DatabaseSchemaUpdater.AddIndex<(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 index to a local database.

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

Syntax

Public Sub AddIndex(Of T) ( _
    indexName As String _
)
public void AddIndex<T>(
    string indexName
)

Type Parameters

  • T
    The entity type corresponding to the applicable database table.

Parameters

  • indexName
    Type: System..::.String
    The name of the index in the corresponding database context.

Remarks

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.
