Step 4: specify the default global variable type for SQLCA
In the Application painter, you must specify the user object
you defined as the default global variable type for SQLCA. When you execute your
application, this tells PowerBuilder to use your standard class
user object instead of the built-in system Transaction object.
Using your own Transaction object instead of SQLCA
This procedure assumes that your application uses the default
Transaction object SQLCA,
but you can also declare and create an instance of your own Transaction
object and then write code that calls the user object as a property of
your Transaction object. For instructions, see the chapter on working
with user objects in the PowerBuilder Users Guide.
To specify the default global variable type for SQLCA:
-
Click the Open button in the PowerBar,
or select File>Open from the menu bar.The Open dialog box displays.
-
Select Applications from the Object Type drop-down
list. Choose the application where you want to use your new user
object and click OK.The Application painter workspace displays.
-
Select the General tab in the Properties view.
Click the Additional Properties button.The Additional Properties dialog box displays.
-
Click the Variable Types tab to display the Variable
Types property page. -
In the SQLCA box,
specify the name of the standard class user object you defined in
Steps 1 through 3:
-
Click OK or Apply.
When you execute your application, PowerBuilder will use the
specified standard class user object instead of the built-in system
object type it inherits from.
