Defaults (PDM)Locate this document in the navigation structure

Default objects are named values that can be assigned to columns or domains. Defaults are available for selection from the Default list on the Check Parameters tab of column and domain property sheets. Defaults are not supported by all DBMSs.

For example, if you must set a default value for all columns of type city, you can create a default object citydflt to assign the value London to it. To review how the default will be generated to your database, click the Preview tab:

create default CITYDFLT as 'London'


In this section:
    Creating a Default
    You can create a default from the Browser or Model menu.
    Default Properties
    To view or edit a default's properties, double-click its Browser or list entry. The property sheet tabs and fields listed here are those available by default, before any customization of the interface by you or an administrator.
    Assigning a Default to a Column or a Domain
    You can select a default from the Default list on the Check Parameters tab of a column or domain property sheet.
    Rebuilding Defaults
    You can generate default objects from default values entered into the Default list on the Check Parameters tab of a column or domain property sheet. The new default objects replace the previously entered values, and can be reused with other columns and domains.
