매개 변수

  • name
    A String, between 1 and 128 characters in length, that specifies the name of the computed field.

    You cannot change the name. To rename a computed field, you must remove the field and then add a new field that has the new name.

주의

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

If you change a field name, 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.

This constructor sets the DigestGrouping property to false.

The following example shows how to define a computed field for a notification class:

NotificationComputedField computedPrice = 
    new NotificationComputedField(flightNotifications, 
    "FormattedPrice");
computedPrice.SqlExpression = "CONVERT(NVARCHAR(10), Price, 1)";
flightNotifications.NotificationComputedFields.Add(computedPrice);
Dim computedPrice As NotificationComputedField = _
    New NotificationComputedField(flightNotifications, _
    "FormattedPrice")
computedPrice.SqlExpression = "CONVERT(NVARCHAR(10), Price, 1)"
flightNotifications.NotificationComputedFields.Add( _
    computedPrice)
