Read Only – PB Docs 2022

Description

Read Only specifies whether PowerBuilder should update the
extended attribute system tables and any other tables in your database.
The extended attribute system tables (also known as the extended
catalog) consist of five tables that contain default extended attribute
information for your database.

The Read Only setting determines whether you can modify (update)
the tables in your database. By default, the Read Only check box is
cleared in the Database Preferences dialog box. This means that
PowerBuilder updates the extended attribute system tables and other
tables in your database when you make changes.

If you select the Read Only check box, PowerBuilder does not
update the extended attribute system tables or any other tables in your
database. You cannot modify (update) information in the extended
attribute system tables or any other database tables from the DataWindow
painter when the Read Only check box is selected.
