Замечания

Field names can contain letters, numbers, and the special characters _ # @ and $. They must also conform to SQL Server identifier conventions. For more information about SQL Server identifiers, see Идентификаторы.

If you update a FieldName element, updating the application deletes and re-creates the notification class to which it corresponds. This includes dropping and re-creating the SQL Server tables used by this notification class. Any data existing in the original notification class tables is permanently deleted.
