Which statement is always true about using OPEN_FORM to open multiple forms in an application?
A. Database transactions are always continued across forms.
B. Code is always shared among forms.
C. A calling form must pass data to a called form.
D. A global record group is always created.
E. Only A and B are true.
F. Only B and C are true.
G. Only C and D are true.
H. None of the statements above are true.
Correct Answer: H
Explanation/Reference:
Explanation:
OPEN_FORM
Opens the indicated form. Use OPEN_FORM to create multiple-form applications, that is, applications that open more than one form at the same time.
OPEN_FORM can be instructed for the two forms to share the same database session and/or library data.
Note:
CALL_FORM
Runs an indicated form while keeping the parent form active. Oracle Forms runs the called form with the same Run form preferences as the parent form. When the called form is exited Oracle Forms processing resumes in the calling form at the point from which you initiated the call to
CALL_FORM.CALL_FORM can be instructed to hide or not hide the calling form, replace or not replace the menu, open the new form in query only mode, share or not share library data.
NEW_FORM
Exits the current form and enters the indicated form. The calling form is terminated as the parent form. If the calling form had been called by a higher form, Oracle Forms keeps the higher call active and treats it as a call to the new form.
Incorrect answers:
A: session_mode:
NO_SESSION (The default.): Specifies that the opened form should share the same database session as the current form.
SESSION: Specifies that a new, separate database session should be created for the opened form.
C: data_mode
NO_SHARE_LIBRARY_DATA (The default.):At runtime, Oracle Forms will not share data between forms that have identical libraries attached (at design time).
SHARE_LIBRARY_DATA: At runtime, Oracle Forms will share data between forms that have identical libraries attached (at design time).
