When does the defineContentAttribute() method return a false? Correct Answer Data stored in its own table

If your fieldtype is storing data in its own table, and doesn’t have any use for a column within the main content table, you may also set defineContentAttribute() to return false. By default, BaseFieldType sets the column to VARCHAR(255), but you can override that with defineContentAttribute().
