Default value control

You can use a default value control to speed up a database insert or query by restricting the action to a limited set of records. The default value control is transparent and does not render anything visible in the user interface. You can place the default value control in a section control, a table control, or in the presentation control.

Properties

Attribute name	Description
Control ID	Each control in a presentation is assigned a unique Control ID that is read-only.
Attribute	Select an attribute from a data source to update or query. You can set an update or query value using one of the following methods: Specify a static value in the Value field. Specify values in the From Data Source ID and the From Attribute fields to read a value from the database.

In the Person application, for example, you can specify DEPARTMENT in the Attribute field and MAINTENANCE in the Value field, to restrict queries to people working in the maintenance department.

From Attribute	If you do not configure a static default value in the Value field, specify a From Attribute that updates or queries the database with its value.
Default Type	Specify the appropriate type of action for this default query.
