Valore proprietà

A String, between 1 and 255 characters in length, that specifies the SQL Server data type.

Osservazioni

Field types must conform to SQL Server data types. The following data types are supported by Notification Services:

bigint	float	real	tinyint
binary	int	smalldatetime	uniqueidentifier
bit	money	smallint	varbinary
char	nchar	smallmoney	varchar
datetime	nvarchar	sql_variant	xml
decimal	numeric

The text, ntext, and image data types are not supported because they cannot be used as values for parameters and variables in stored procedures. In addition, the timestamp data type is not supported. For more information about SQL Server data types, see Tipi di dati (Motore di database).

If using the xml data type with the XSLT content formatter, the content formatter might attempt to transform the XML data. To preserve the XML markup, set the content formatter's DisableEscaping argument to false.

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

Esempio

The following examples show how to define an event field that has a data type of nvarchar(6):

// Define a destination field and add it before the Price field
EventField eventDestination = 
    new EventField(flightEvents, "GoingTo");
eventDestination.Type = "nvarchar(6)";
flightEvents.EventFields.Add(eventDestination, "Price");

' Define a destination field and add it before the Price field.
Dim eventDestination As EventField = _
    New EventField(flightEvents, "GoingTo")
eventDestination.Type = "nvarchar(6)"
flightEvents.EventFields.Add(eventDestination, "Price")

Thread Safety

Any public static (Shared in Microsoft Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
