Protocols Element (ADF)

Contains elements that define one or more delivery protocols used by the notification class to deliver notifications.

语法

<NotificationClasses>
    <NotificationClass>
        ...
        <Protocols>

Element Characteristics

Characteristic	Description
Data type and length	None.
Default value	None.
Occurrence	Optional once per NotificationClass element.
Updates	Can be added and deleted when updating the application.

Element Relationships

Relationship	Elements
Parent element	NotificationClass Element (ADF)
Child elements	Protocol Element (ADF)

备注

The child elements of the Protocols element define one or more delivery protocols used by the notification class. Each notification class must have at least one delivery protocol used to deliver notifications.

If you add or delete a Protocols 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 SQL Server tables is permanently deleted.

示例

The following example shows how to define two delivery protocols, one built-in SMTP and one custom HTTPLogger, for a notification class.

<Protocols>
    <Protocol>
        <ProtocolName>SMTP</ProtocolName>

                <SqlExpression>
                'Stock notification: '
                    +CONVERT (NVARCHAR(30), GETDATE())
                </SqlExpression>
            </Field>
            <Field>
                <FieldName>SubscriberId</FieldName>
