object groups
01. what ia an object groups?
An object group is a container for a group of objects, you define an object group when you want to package
related objects. so that you copy or reference them in another modules.
02. what are the different objects that you cannot copy or reference in object groups?
objects of differnt modules
another object groups
individual block dependent items
program units.
canvas views
03. what are different types of canvas views?
content canvas views
stacked canvas views
horizontal toolbar
vertical toolbar.
04. explain about content canvas views?
Most Canvas views are content canvas views a content canvas view is the "base" view that occupies the entire
content pane of the window in which it is displayed.
05. Explain about stacked canvas views?
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?
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?
Get_view_property, Set_view_property
Windows
07. What is relation between the window and canvas views?
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.
08. What are the different modals of windows?
Modalless windows
Modal windows
09. What are modalless windows?
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.
10. What are modal windows?
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.
11. How do you display console on a window ?
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.
12. What is the remove on exit property?
For a modelless window, it determines whether oracle forms hides the window automatically when the operators
navigates to an item in the another window.
13. How many windows in a form can have console?
Only one window in a form can display the console, and you cannot chage the console assignment at runtime.
14. Can you have more than one content canvas view attached with a window?
Yes.
Each window you create must have atleast one content canvas view assigned to it. You can also create a
window that has manipulate contant canvas view. At run time only one of the content canvas views assign to a
window is displayed at a time.
15. What are the different window events activated at runtimes?
When_window_activated
When_window_closed
When_window_deactivated
When_window_resized
Within this triggers, you can examine the built in system variable system.event_window to determine the
name of the window for which the trigger fired.
Modules
27. What are different types of modules available in oracle form?
Form module - a collection of objects and code routines
Menu modules - a collection of menus and menu item commands that together make up an application menu

.fmx - form module executable
19. What are the default extentions of the files created by menu module?
.mmb, .mmx
20 What are the default extension of the files created by library module?
The default file extensions indicate the library module type and storage format
.pll - pl/sql library module binary
Master Detail
21. What is a master detail relationship?
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?
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?
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 witjh the new master record. These operations are accomplished through the execution
of triggers.
24. What are Most Common types of Complex master-detail relationships?
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?
Cascade
Isolate
Non-isolote
26. What are the different defaust triggers created when Master Deletes Property is set to Non-isolated?
Master Delets Property Resulting Triggers
----------------------------------------------------
Non-Isolated(the default) On-Check-Delete-Master
On-Clear-Details
On-Populate-Details
26. Whar 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?
Master Deletes Property Resulting Triggers
---------------------------------------------------
Isolated On-Clear-Details
On-Populate-Details
29. What are the Coordination Properties in a Master-Detail relationship?
The coordination properties are
Deferred
Auto-Query
These Properties determine when the population phase of block
coordination should occur.
30. What are the different types of Coordinations of the Master with the Detail block?
42. What is the User-Named Editor?
A user named editor has the same text editing functionality as the default editor, but, becaue it is a named
object, you can specify editor attributes such as windows display size, position, and title.
43. What are the Built-ins to display the user-named editor?
A user named editor can be displayed programmatically with the built in procedure SHOW-EDITOR,
EDIT_TETITEM independent of any particular text item.
44. What is the difference between SHOW_EDITOR and EDIT_TEXTITEM?
Show editor is the generic built_in which accepts any editor name and takes some input string and returns
modified output string. Whereas the edit_textitem built_in needs the input focus to be in the text item before
the built_in is excuted.
45. What is an LOV?
An LOV is a scrollable popup window that provides the operator with either a single or multi column selection list.
46. What is the basic data structure that is required for creating an LOV?
Record Group.
47. What is the "LOV of Validation" Property of an item? What is the use of it?
When LOV for Validation is set to True, Oracle Forms compares the current value of the text item to the values
in the first column displayed in the LOV.
Whenever the validation event occurs.
If the value in the text item matches one of the values in the first column of the LOV, validation
succeeds, the LOV is not displayed, and processing continues normally.
If the value in the text item does not match one of the values in the first column of the LOV, Oracle Forms
displays the LOV and uses the text item value as the search criteria to automatically reduce the list.
48. What are the built_ins used the display the LOV?
Show_lov
List_values
49. What are the built-ins that are used to Attach an LOV programmatically to an item?
set_item_property
get_item_property
(by setting the LOV_NAME property)
50. What are the built-ins that are used for setting the LOV properties at runtime?
get_lov_property
set_lov_property
51. What is a record group?
A record group is an internal Oracle Forms that structure that hs a column/row framework similar to a
database table. However, unlike database tables, record groups are separate objects that belong to the form
module which they are defined.
52. How many number of columns a record group can have?
A record group can have an unlimited number of columns of type CHAR, LONG, NUMBER, or DATE provided that
the total number of column does not exceed 64K.
53. What is the Maximum allowed length of Record group Column?
Record group column names cannot exceed 30 characters.
54. What are the different types of Record Groups?
Query Record Groups
NonQuery Record Groups
State Record Groups
55. What is a Query Record Group?
A query record group is a record group that has an associated SELECT statement. The columns in a query
record group derive their default names, data types, had lengths from the database columns referenced in the
SELECT statement. The records in query record group are the rows retrieved by the query associated with that
record group.
56. What is a Non Query Record Group?
A non-query record group is a group that does not have an associated query, but whose structure and values can
be modified programmatically at runtime.
57. What is a Static Record Group?
A static record group is not associated with a query, rather, you define its structure and row values at design
time, and they remain fixed at runtime.
58. What are the built-ins used for Creating and deleting groups?

parameters
66. What are parameters?
Parameters provide a simple mechanism for defining and setting the values
of inputs that are required by a form at startup. Form parameters are variables of type char,number,date that
you define at design time.
67. What are the Built-ins used for sending Parameters to forms?
You can pass parameter values to a form when an application executes the call_form, New_form, Open_form or
Run_product.
68. What is the maximum no of chars the parameter can store?
The maximum no of chars the parameter can store is only valid for char parameters, which can be upto
64K. No parameters default to 23Bytes and Date parameter default to 7Bytes.
69. How do you call other Oracle Products from Oracle Forms?
Run_product is a built-in, Used to invoke one of the supported oracle tools products and specifies the name of
the document or module to be run. If the called product is unavailable at the time of the call, Oracle Forms
returns a message to the opertor.
70. How do you reference a Parameter?
In Pl/Sql, You can reference and set the values of form parameters using bind variables syntax. Ex.
PARAMETER name = '' or :block.item = PARAMETER
Parameter name
71. How do you reference a parameter indirectly?
To indirectly reference a parameter use the NAME IN, COPY 'built-ins to indirectly set and reference the
parameters value' Example name_in ('capital parameter my param'), Copy ('SURESH','Parameter my_param')
72. What are the different Parameter types?
Text Parameters
Data Parameters
73. When do you use data parameter type?
When the value of a data parameter being passed to a called product is always the name of the record
group defined in the current form. Data parameters are used to pass data to produts invoked with the
run_product built-in subprogram.
74. Can you pass data parametrs to forms?
No.
IMAGES
75. What are different types of images?
Boiler plate images
Image Items
76. What is the difference between boiler plat images and image items?
Boiler plate Images are static images (Either vector or bit map) that you import from the file system or
database to use a grapical elements in your form, such as company logos and maps Image items are
special types of interface controls that store and display either vector or bitmap images. Llike other items
that store values, image items can be either base table items(items that relate directly to database columns)
or control items. The definition of an image item is stored as part of the form module FMB and FMX files, but
no image file is actualy associated with an image item until the item is populate at run time.
77. What are the trigger associated with image items?
When-image-activated fires when the operators double clicks on an image item when-image-pressed
fires when an operator clicks or double clicks on an image item
78. What is the use of image_zoom built-in?
To manipulate images in image items.
WORKING WITH MULTIPLE FORMS
79. How do you create a new session while open a new form?
Using open_form built-in setting the session option Ex. Open_form('Stocks ',active,session). when invoke the
mulitiple forms with open form and call_form in the same application, state whether the following are
true/False
80. Any attempt to navigate programatically to disabled form in a call_form stack is allowed?
False
81. An open form can not be execute the call_form procedure if you chain of called forms has been initiated by
another open form?
True
82. When a form is invoked with call_form, Does oracle forms issues a save point?
True
Mouse Operations
83. What are the various sub events a mouse double click event involves?

Object Linking & Embadding provides you with the capability to integrate objects from many Ms-Windows
applications into a single compound document creating integrated applications enables you to use the features
form .
86. What is the difference between object embedding & linking in Oracle forms?
In Oracle forms, Embedded objects become part of the form module, and linked objects are references from
a form module to a linked source file.
87. What is the difference between OLE Server & Ole Container?
An Ole server application creates ole Objects that are embedded or linked in ole Containers ex. Ole servers
are ms_word & ms_excell. OLE containers provide a place to store, display and manipulate objects that are
created by ole server applications. Ex. oracle forms is an example of an ole Container.
88. What are the different styles of actvation of ole Objects?
In place activation
External activation
ViSUAL Attributes & property clauses
89. What are visual attributes?
Visual attributes are the font, color, pattern proprities that you set for form and menu objects that appear in your
application interface.
90. What is a property clause?
A property clause is a named object that contains a list of properties and thier settings. Once you create a
property clause you can base other object on it. An object based on a property can inherit the setting of any
property in the clause that makes sense for that object.
91. Can a property clause itself be based on a property clause?
Yes
92. What are the important difference between property clause and visual attributes?
Named visual attributes differed only font, color & pattern attributes, property clauses can contain this and any
other properties. You can change the appearance of objects at run time by changing the named visual
attributes programatically , property clause assignments cannot be changed programatically. When an object is
inheriting from both a property clause and named visual attribute, the named visual attribute settings take
precedence, and any visual attribute properties in the class are ignored.
Form Build-ins
93. What is a Text_io Package?
It allows you to read and write information to a file in the file system.
94. What is an User_exit?
Calls the user exit named in the user_exit_string. Invokes a 3Gl programe by name which has been
properly linked into your current oracle forms executable.
95. What is synchronize?
It is a terminal screen with the internal state of the form. It updates the screen display to reflect the
information that oracle forms has in its internal representation of the screen.
96. What is forms_DDL?
Issues dynamic Sql statements at run time, including server side pl/SQl and DDL
Triggers
97. What is WHEN-Database-record trigger?
Fires when oracle forms first marks a record as an insert or an update. The trigger fires as soon as oracle forms
determines through validation that the record should be processed by the next post or commit as an insert or
update. c generally occurs only when the operators modifies the first item in the record, and after the operator
attempts to navigate out of the item.
98. What are the master-detail triggers?
On-Check_delete_master
On_clear_details
On_populate_details
99. What is the difference between $$DATE$$ & $$DBDATE$$
$$DBDATE$$ retrieves the current database date
$$date$$ retrieves the current operating system date.
100. What is system.coordination_operation?
It represents the coordination causing event that occur on the master block in master-detail relation.
101. What are the difference between lov & list item?
Lov is a property where as list item ias an item. A list item can have only one column, lov can have one or more
columns.
102. What are the different display styles of list items?
Pop_list
Text_list
Combo box
103. What is pop list?
The pop list style list item appears initially as a single field (similar to a text item field). When the operator
selects the list icon, a list of available choices appears.
104. What is a text list?
The text list style list item appears as a rectangular box which displays the fixed number of values. When the
text list contains values that can not be displayed, a vertical scroll bar appears, allowing the operator to view and
select undisplayed values.
105. What is a combo box?
A combo box style list item combines the features found in list and text item. Unlike the pop list or the text
list style list items, the combo box style list item will both display fixed values and accept one operator
entered value.
106. What are display items?
Display items are similar to text items with the exception that display items only store and display fetched or
assigned values.Display items are generaly used as boilerplate or conditional text.
107. What is difference between open_form and call_form?
when one form invokes another form by executing open_form the first form remains displayed,and operators
can navigate between the forms as desired. when one form invokes another form by executing call_form,the
called form is modal with respect to the calling form.That is, any windows that belong to the calling form are
disabled, and operators cannot navigate to them until they first exit the called form.
108. What is new_form built-in?
When one form invokes another form by executing new_form oracle form exits the first form and releases its
memory before loading the new form calling new form completely replace the first with the second. If there are
changes pending in the first form,the operator will be prompted to save them before the new form is loaded.
109. What is a library?
A library is a collection of subprograms including user named procedures, functions and packages.
110. What is the advantage of the library?
Library's provide a convenient means of storing client-side program units and sharing them among multipule
applications. Once you create a library, you can attach it to any other form,menu,or library modules. When you
can call library program units from triggers menu items commands and user named routine, you write in the
modules to which you have attach the library.
when a library attaches another library ,program units in the first library can reference program units in the
attached library. Library support dynamic loading-that is library program units are loaded into an
application only when needed. This can significantly reduce the run-time memory requirements of an
applications.
111. What is strip sources generate options?
Removes the source code from the library file and generates a library files that contains only pcode.The
resulting file can be used for final deployment, but can not be subsequently edited in the designer.
ex. f45gen module=old_lib.pll userid=scott/tiger
strip_source YES output_file
112.What are the vbx controls?
Vbx control provide a simple mehtod of buildig and enhancing user interfaces.The controls can use to
obtain user inputs and display program outputs.vbx control where originally develop as extensions for the ms
visual basic environments and include such items as sliders,grides and knobs.
113. What is a timer?
Timer is a "internal time clock" that you can programmatically create to perform an action each time the timer
expires.
114. What are built-ins associated with timers?
find_timer
create_timer
delete_timer
115. what are difference between post database commit and post-form commit?
Post-form commit fires once during the post and commit transactions process, after the database commit
occures. The post-form-commit trigger fires after inserts,updates and deletes have been posted to the
database but before the transactions have been finalished in the issuing the command.The post-database-
commit trigger fires after oracle forms issues the commit to finalished transactions.
116. What is a difference between pre-select and pre-query?
Fires during the execute query and count query processing after oracle forms constructs the select
statement to be issued, but before the statement is actually issued.
The pre-query trigger fires just before oracle forms issues the select statement to the database after the
operator as define the example records by entering the query criteria in enter query mode.
Pre-query trigger fires before pre-select trigger.
117. What is trigger associated with the timer?
When-timer-expired.
118 What is the use of transactional triggers?
Using transactional triggers we can control or modify the default functionality of the oracle forms.

A placeholder column is used to hold a calculated values at a specified place rather than allowing is to appear
in the actual row where it has to appeared.
26. What is the use of hidden column?
A hidden column is used to when a column has to embedded into boilerplate text.
27. What is the use of break group?
A break group is used to display one record for one group ones.While multiple related records in other group
can be displayed.
28. If two groups are not linked in the data model editor, What is the hierarchy between them?
Two group that is above are the left most rank higher than the group that is to right or below it.
29.The join defined by the default data link is an outer join yes or no?

An anchoring object is a print condition object which used to explicitly or implicitly anchor other objects to itself.
43. What is a physical page ? & What is a logical page ?
A physical page is a size of a page. That is output by the printer. The
logical page is the size of one page of the actual report as seen in the
Previewer.

model.
Because for each query, report has to open a separate cursor and has to
rebind, execute and fetch data.
53. What are the various methods of performing a calculation in a report ?
1. Perform the calculation in the SQL statements itself.
2. Use a calculated / summary column in the data model.
54. Which of the above methods is the faster method?
performing the calculation in the query is faster.
55. Why is a Where clause faster than a group filter or a format trigger?
Because, in a where clause the condition is applied during data retrieval
than after retrieving the data.
