<SqlExpression> Element (<ComputedField>)

SQL Server 2000

Specifies a valid Transact-SQL expression that provides the computed field value.

Structure

<NotificationClasses>
   <NotificationClass>
      ...
      <Schema>
         ...
         <ComputedFields>
            <ComputedField>
               ...
               <SqlExpression>

Element Characteristics

Characteristic	Description
Data Type	string, between 0 and 4,000 characters in length.
Default Value	None.
Occurrence	Required once per <ComputedField> node.
Updates	Can be modified, but not added or deleted, using NSControl Update.

Element Relationships

Relationship	Elements
Parent Node	<ComputedField> Node

Remarks

If you update a <SqlExpression> element, NSControl Update 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.

Important If you update a <SqlExpression> element, any data existing in the original SQL Server tables is permanently deleted.
