02. what are the different objects that you cannot copy or reference in object groups?

ANS:- objects of different modules another object groups individual block dependent items program units.

canvas views:-

03. what are different types of canvas views?

05. Explain about stacked canvas views?

ANS:- Stacked canvas view is displayed in a window on top of, or "stacked" on the content canvas view assigned to that same window. Stacked canvas views obscure some part of the underlying content canvas view, and or often shown and hidden programmatically.

06. Explain about horizontal, Vertical tool bar canvas views?

ANS:- Tool bar canvas views are used to create tool bars for individual windows Horizontal tool bars are display at the top of a window, just under its menu bar.
Vertical Tool bars are displayed along the left side of a window

07. Name of the functions used to get/set canvas properties?

ANS:- Get_view_property, Set_view_property

Windows:-

08. What is relation between the window and canvas views?

ANS:- Canvas views are the back ground objects on which you place the interface items (Text items), check boxes, radio groups etc.,) and boilerplate objects (boxes, lines, images etc.,) that operators interact with us they run your form . Each canvas views displayed in a window.

09. What are the different modals of windows?

ANS:- Modal less windows , Modal windows

10. What are modal less windows?

ANS:- More than one modelless window can be displayed at the same time, and operators can navigate among them if your application allows them to do so . On most GUI platforms, modelless windows can also be layered to appear either in front of or behind other windows.

11. What are modal windows?

ANS:- Modal windows are usually used as dialogs, and have restricted functionality compared to modelless windows. On some platforms for example operators cannot resize, scroll or iconify a modal window.

12. How do you display console on a window ?

ANS:- The console includes the status line and message line, and is displayed at the bottom of the window to which it is assigned. To specify that the console should be displayed, set the console window form property to the name of any window in the form. To include the console, set console window to Null.

13. What is the remove on exit property?

ANS:- For a modelless window, it determines whether oracle forms hides the window automatically when the operators navigates to an item in the another window.

14. How many windows in a form can have console?

ANS:- Only one window in a form can display the console, and you cannot change the console assignment at runtime.

15. Can you have more than one content canvas view attached with a window?

ANS:- Yes. Each window you create must have at least one content canvas view assigned to it. You can also create a window that has manipulate content canvas view. At run time only one of the content canvas views assign to a window is displayed at a time.

Master Detail:-

21. What is a master detail relationship?

ANS:- A master detail relationship is an association between two base table blocks- a master block and a detail block. The relationship between the blocks reflects a primary key to foreign key relationship between the tables on which the blocks are based.


22. What is coordination Event?

ANS:- Any event that makes a different record in the master block the current record is a coordination causing event.

23. What are the two phases of block coordination?

ANS:- There are two phases of block coordination: the clear phase and the population phase. During, the clear phase, Oracle Forms navigates internally to the detail block and flushes the obsolete detail records. During the population phase, Oracle Forms issues a SELECT statement to repopulate the detail block with detail records associated with the new master record. These operations are accomplished through the execution of triggers.

24. What are Most Common types of Complex master-detail relationships?

ANS:- There are three most common types of complex master-detail relationships:
master with dependent details, master with independent details, detail with two masters

25. What are the different types of Delete details we can establish in Master-Details?
ANS:- Cascade, Isolate, Non-isolote

26. What are the different default triggers created when Master Deletes Property is set to Non-isolated?
ANS:- Master Delets Property Resulting Triggers

Non-Isolated(the default) On-Check-Delete-Master
On-Clear-Details
On-Populate-Details

27. What are the different default triggers created when Master Deletes Property is set to Cascade?
Ans: Master Deletes Property Resulting Triggers, Cascading On-Clear-Details, On-Populate-Details, Pre-delete

28. What are the different default triggers created when Master Deletes Property is set to isolated?

ANS:- Master Deletes Property Resulting Triggers, Isolated On-Clear-Details, On-Populate-Details

29. What are the Coordination Properties in a Master-Detail relationship?
ANS:- The coordination properties are Deferred, Auto-Query . These Properties determine when the population phase of block coordination should occur.

When invoking this procedure, you encounter the error: ORA-00001: Unique constraint (SCOTT.THEATER_NAME_UK) violated.How should you modify the function to handle this error?
a. An user defined exception must be declared and associated with the error code and handled in the EXCEPTION
section.
b. Handle the error in EXCEPTION section by referencing the error code directly.
c. Handle the error in the EXCEPTION section by referencing the UNIQUE_ERROR predefined exception.
d. Check for success by checking the value of SQL%FOUND immediately after the UPDAT statement.

END;
You are about to add an argument to CALCULATE_BUDGET. What effect will this have?
a. The GET_BUDGET function will be marked invalid and must be recompiled before the next execution.
b. The SET_BUDGET function will be marked invalid and must be recompiled before the next execution.
c. Only the CALCULATE_BUDGET procedure needs to be recompiled.
d. All three procedures are marked invalid and must be recompiled.

Which procedure can be used to create a customized error message?

Under which circumstance must you recompile the package body after recompiling the package specification?
a. Altering the argument list of one of the package constructs
b. Any change made to one of the package constructs
c. Any SQL statement change made to one of the package constructs
d. Removing a local variable from the DECLARE section of one of the package constructs

Procedure and Functions are explicitly executed. This is different from a database trigger. When is
a database trigger executed?
a. When the transaction is committed
b. During the data manipulation statement
c. When an Oracle supplied package references the trigger
d. During a data manipulation statement and when the transaction is committed

Which Oracle supplied package can you use to output values and messages from database triggers, stored procedures and functions within SQL*Plus?
a. DBMS_DISPLAY

What occurs if a procedure or function terminates with failure without being handled?
a. Any DML statements issued by the construct are still pending and can be committed or rolled back.
b. Any DML statements issued by the construct are committed
c. Unless a GOTO statement is used to continue processing within the BEGIN section, the construct terminates. The
construct rolls back any DML statements issued and returns the unhandled exception to the calling environment.

Examine this code
BEGIN
theater_pck.v_total_seats_sold_overall := theater_pck.get_total_for_year;
END;
For this code to be successful, what must be true?
a. Both the V_TOTAL_SEATS_SOLD_OVERALL variable and the GET_TOTAL_FOR_YEAR function must exist only in the body
of the THEATER_PCK package.
b. Only the GET_TOTAL_FOR_YEAR variable must exist in the specification of the THEATER_PCK package.
c. Only the V_TOTAL_SEATS_SOLD_OVERALL variable must exist in the specification of the THEATER_PCK package.
d. Both the V_TOTAL_SEATS_SOLD_OVERALL variable and the GET_TOTAL_FOR_YEAR function must exist in the specification of the THEATER_PCK package.

A stored function must return a value based on conditions that are determined at runtime. Therefore, the SELECT statement cannot be hard-coded and must be created dynamically when he function is executed. Which Oracle supplied package will enable this feature?
