Use Extended Attributes database preference
Description
Controls access to the extended attribute system tables by
specifying whether you want PowerBuilder to create these tables. The
extended attribute system tables (also known as the extended catalog)
consist of five tables that contain default extended attribute information
for your database.
By default, the Use Extended Attributes check box is selected
in the Database Preferences dialog box. This setting creates the
extended attribute system tables the first time you connect to a
database using PowerBuilder.
