Notes
Notification Services automatically adds SubscriberID, Created, Updated, and Enabled fields to the subscription class schema.
If you add or delete a Field, updating the application re-creates the subscription class to which it corresponds. A new subscription table is created, and the existing subscription table is renamed to SubscriptionTableNameOld. Existing subscription table indexes are left unchanged.
If you want to transfer data between the old and new subscription tables, it must be done manually. For more information, see Mise à jour d'une application.
Exemple
The following example shows the definition of a SubscriberLocale subscription field.
<Field>
<FieldName>SubscriberLocale</FieldName>
<FieldType>nvarchar(10)</FieldType>
<FieldTypeMods>NOT NULL</FieldTypeMods>
</Field>
