How to Define a Subtype Table

Previous Next

To define a subtype table:

Identify the table that is the supertype table.

Define the columns that are specific to the subtype.

USoft Developer will automatically insert the primary key fields to link the subtype to its supertype.

You can define a subtype table by filling out a form (an info window) or by using the New Subtype wizard. Once the subtype table exists, you can modify it by double-clicking its name in the Project Catalog where it will appear as a subnode of the supertype table.
