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.
Applies to
All database interfaces
In an application
You cannot set the Use Extended Attributes database preference in
code.
In the development
environment
In the Database painter, select or clear the Use Extended
Attributes check box in the Database Preferences dialog box as
follows:
-
Select the check box
(Default) Creates the extended attribute system tables when
connecting to the database for the first time. -
Clear the check box
Does not create the extended attribute system tables if they
do not exist. Instead, the DataWindow painter use the appropriate
default values for extended attributes (such as headers, labels, and
text color). If the extended attribute system tables already exist,
PowerBuilder does not use them when you create a new DataWindow
object.
Default value
The Use Extended Attributes check box in the Database Preferences
dialog box is selected by default.
Usage
If you clear the Use Extended Attributes check box in the Database
Preferences dialog box, PowerBuilder does not do any of the
following:
-
Create the extended attribute system tables
-
Insert, update, or delete rows in the extended attribute
system tables -
Select information (such as header names) from the extended
attribute system tables -
Execute statements that reference the extended attribute
system tables
