Notas
FieldType values 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 |

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 Tipos de datos (motor de base de datos).
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 update a FieldType element, 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. |
Ejemplo
