Oracle Report Interview Questions
1. What are the types of layouts in reports?
There are 8 default layout style provided.
a) Tabular - It is the
most basic type of report where each column corresponds to a column selected
from the database.
b) Form-like - It is a
report one record per page. The field value is placed to the field labels.
c) Mailing Label - A
mailing label report prints mailing labels in multiple columns on each page.
The printing can be a landscape or a portrait.
d) Form Letter - A Form
letter report contains database values embedded into any text that is entered
or imported into the report editor.
e) Group Left - A group left report
divides the rows of a table into sets, based on a common value in
one of the columns. This style is used to restrict a column from repeating the
same value several times while values of related columns change.
f) Group Above - A group above repot
contains two or more groups of data. For every value of the master group, the
related values of the detail group(s) are fetched from the database.
g) Matrix - A matrix (cross tab) report
contain one row of tables, one column of labels and information in a grid
format that is related to the row and column labels.
A distinguished feature of matrix report is that the number of
columns is not known until the data is fetched from the database.
To create a matrix report, at
least four groups are required. One group must be a cross-product group, two
of the groups must be within the cross-product group to furnish the labels, and
at least one group must provide the information to fill the cells. The groups
can provide to a single query or to multiple queries.
h) Matrix with Group: A matrix with group
report is a group above report with a separate matrix for each value of the
master group.
2. What are the different layout objects?
There are 4 types of layout objects.
a) Repeating Frames.
b) Frames.
c) Fields.
d) Boilerplate.
a) Frames:
Frames surrounds other layout objects, enabling control of multiple objects
Simultaneously, ensuring that they maintain their positions relative
to each other in the report. A frame might be used to surround all objects
owned by a group, to surround column labels.
b) Repeating Frames:
Repeating frames act as placeholder for groups (repeating values) and present
rows of data retrieved from the database. Repeating frames repeat as often as
the number of rows retrieved.
c) Fields: Fields act as
placeholder for column values; they define the formatting attributes for all
columns displayed in the report. A field is one of the objects that can be
located inside a frame or repeating frame.
d) Boilerplate:
Boilerplate consists of text and graphics that appear in a report each time it
is run; e.g., a label appearing above a column of data is boilerplate text.
Graphics drawn in the layout as well as text added to the layout are
boilerplate.
3. What is data model?
To specify the data for the report, a data model should be defined.
A data model is composed of some or all of the following data definition
objects.
a) Queries - Queries are
ANSI-standard SQL SELECT statements that fetch data from a standard database
such as Oracle, DB2 etc. These SELECT statements are fired each time the report
is run.
You can select any number of queries to select data from any number
of tables.
b) Groups - Groups
determine the hierarchy of data appearing in the report, and are primarily used
to create breaks in the report. Oracle report automatically creates a group for
each query, but you are not limited to this default. You can create a new group
in the data model and included a column that you want to use as the break
column.
c) Column - Column
contain the data values for a report. Default report columns, corresponding to
the table columns included in each query's SELECT list are automatically
created by the table Oracle Report, and then each column is placed in the group
associated with the query that selected the column. If you want to perform
summaries and computations on the database column values, you can create new
columns. You can also reassign one or more columns to a group you've created.
d) Parameters -
Parameters are visible for your reports that enable you to change selection
criteria at runtime. Oracle Report automatically creates a set of system
parameters at runtime, but you can create your own as well. You can create
parameters to replace either single literal values or entire expressions in any
part of a query. You can reference parameters elsewhere in the report, such as
in PL/SQL constructs providing conditional logic for the report.
e) Data
Link - Data link are used to establish parent-child relationship between
queries and groups via column matching.
4. What is anchor?
Anchors fasten an edge of one object to an edge of another object,
ensuring that they maintain their relative positions. For example, you can
anchor boilerplate text to the edge of a variable-sized repeating frame,
guaranteeing the boilerplate's distance and position in relation to the
repeating frame, no matter how the frame's size might change.
5. What types of triggers are there in report?
As a general rule, any processing that will affect the data retrieved
by the report should
be performed in the Before Parameter Form and After Parameter Form
trigger.(These are the two report trigger that fire before anything is parsed
or fetched). There are five global report triggers. You cannot create new
global report triggers. The trigger names indicate at point trigger fires:
1. Before Report: Fires
before the report is executed but after queries are parsed.
2. After Report: Fires
after you exit the Previewed, or after report output is sent to a specified
destination, such as a file, a printer, or an Oracle Office userid. This
trigger can be used to clean up any initial processing that was done, such
as deleting tables. Note,
however, that this trigger always fires, whether or not your report
completed successfully.
3. Between Pages: Fires
before each page of the report is formatted, except the very first page. This
trigger can be used for customized page formatting. In the Previewer, this
trigger only fires the first time that you go to page. If you subsequently
return to the page, the trigger does not fire again.
4. Before Parameter Form:
Fires before the Runtime Parameter Form is displayed. From this trigger, you
can access and change the values of parameters, PL/SQL global variables, and
report-level columns. If the Runtime Parameter Form is suppressed, this trigger
still fires. Consequently, you can use this trigger for validation of command
line parameters.
5. After Parameter Form:
Fires after the Runtime Parameter Form is displayed. From this trigger, you can
access parameters and check their values. This trigger can also be used to
change parameter values or, if an error occurs, return to the Runtime Parameter
Form. Columns from the data model are not accessible from this trigger. If the
Runtime Parameter Form is suppressed, the After Parameter Form trigger still
fires. Consequently, you can use this trigger for validation of command line
parameters or other data.
6. What is the order of
execution of report trigger?
Order
of execution of report trigger:
1. Before Parameter Form trigger is fired.
2. Runtime Parameters Form appears (if not suppressed).
3. After Parameters Form trigger is fired (unbless the user
cancels from the Runtime
Parameter Form).
4. Report is "compiled".
5. Queries are parsed.
6. Before Report trigger is fired.
7. Set TRANSACTION READONLY is executed (if specified via the
READONLY
argument or setting).
8. The report is executed and the Between Pages trigger fires for
each page except the last one. (Note that data can be fetched at any time while
the report is being formatted).
7. What is Group filter?
A group filter is a PL/SQL function that determines which records to
include in a group, if the Filter Type property is POL/SQL. The function must
return a boolean value. Depending on whether the function returns TRUE of
FALSE, the current record is included or excluded from the report. You can
access group filters from the Object Navigator, the Property Palette (the PL/SQL
Filter property), or the PL/SQL Editor.
Definition Level: Group
On Failure: Excludes the current record from the group.
Example:
function filter_comm return boolean is
begin
if
:comm IS NOT NULL then
if :comm < 100 then
return(FALSE);
else
return(TRUE);
end if;
else
return(FALSE); -- for rows with NULL commissios
end
if;
end;
8. What is Formula
Column?
Formula is PL/SQL functions that populate formula or placeholder
columns. You can access the PL/SQL for formulas from the Object Navigator, the
PL/SQL Editor, or the Property Palette (i.e. PL/SQL Formula property). A column of data
type Number can only have a formula that returns a value of data type Number. A
column of data type Date can only have a formula that returns a value of data
type Date. A column of data type Character can only have a formula that returns
a value of datatype CHARACTER, VARCHAR, or VARCHAR2.
Definition Level: column
On Failure: No value is returned for the column.
For
example1: formula for adding values
function salcomm return NUMBER is
beign
return(:sal + :comm);
end;
For
example2: formula with
condition
function calcomm return NUMBER is
temp number;
beign
if
:comm IS NOT NULL then
temp := :sal + :comm;
else
temp := :sal;
end
if;
return(:temp);
end;
9. What is Place holder Columns?
A placeholder is a column is an empty container at design time. The
placeholder can hold a value at run time has been calculated and placed in to
it by pl/sql code from anther object.
You can set
the value of a placeholder column is in a Before Report trigger.
Store a Temporary value for future reference. EX. Store the current
max salary as records is retrieved.
10. How many types of columns are there and what are
they
1. Formula columns: For
doing mathematical calculations and returning one value. formulas column
compute their values using PL/SQL expressions. Formula can operate on multiple
values per record
(e.g.:avg_price*: quantity).
2. Summary Columns: For
doing summary calculations such as summations etc.
3.
Place holder Columns: These columns are useful for
storing the value in a variable.
11. What is Validation
trigger?
Validation trigger are PL/SQL functions that are executed when
parameter values are specified on the command line and when you accept the
Runtime Parameter Form. (Notice that this means each validation trigger
may fire twice when you execute the report) Validation trigger are also used to
validate the Initial Value property of the parameter. The function must return
a boolean value.
Definition
Level: parameter
On
Failure: The user is return to the parameter value
in the Runtime Parameter Form where they can either change it or cancel the
Runtime Parameter Form.
For Example
/* this function prevent the runtime user
from sending report output anywhere except a printer*/
function DESTYPEValidTrigger return boolean
is
begin
if
upper(:DESTYPE) = 'PRINTER' Then
Return(true);
else
Return(False);
end
if;
end;
On Failure: No value is returned for the
column.
12. What is Format
trigger?
Format triggers are PL/SQL functions executed before the object is formatted.
The trigger can be used to dynamically change the formatting attributes of the object.
The function must return a Boolean value (TRUE or FALSE). Depending on whether
the function returns TRUE or FALSE, the current instance of the object is included or
excluded from the report output. You can access format triggers from the Object
Navigator, the Property Palette, or the PL/SQL Editor.
Definition Level: layout object
On Failure: Excludes the
current instance of the object from the output.
Format trigger example (highlighting a value)
/* suppose that you are building a banking report and would like it
to indicate if a customer is overdrawn. To do so, you give the repeating frame
around the customer information a format trigger that causes it to have a
border only if a customer's account balance is less than 0 (or the required
minimum balance). */
function my_formtrig return BOOLEAN is begin
if: bal < 0 then
srw.attr.mask :=
SRW.BORDERWIDTH_ATTR;
srw.attr.borderwidth := 1;
srw.set_attr (0,
srw.attr);
end if;
return (true);
end;
13. What is Action
trigger?
Action triggers are PL/SQL procedures executed when a button is
selected in the Runtime Previewer. The trigger can be used to dynamically call
another report (drill down) or execute any other PL/SQL. You can access action
triggers from the Object Navigator, the Property Palette (PL/SQL Trigger
property), or the PL/SQL Editor.
Definition Level: button
14. What is Ref cursor
query?
A ref cursor query uses PL/SQL to fetch data for the report. In a
ref cursor query, you specify a PL/SQL function that returns a cursor value
from a cursor variable.
Definition Level: query
On Failure: No data is returned to the query.
Package with ref cursor and function example this package spec and
body define a ref cursor type as well as a function that uses the ref cursor to
return data. The function could be referenced from the ref cursor query, which
would greatly simplify the PL/SQL in the query itself. If creating this spec
and body as a stored procedure in a tool such as SQL*Plus, you would need
to use the CREATE PACKAGE and CREATE
PACKAGE BODY commands. */
PACKAGE cv IS
type comp_rec is RECORD
(deptno number,
ename varchar(10),
compensation number);
type comp_cv is REF CURSOR return comp_rec;
function emprefc(deptno1 number) return comp_cv;
END;
PACKAGE BODY cv IS
function emprefc(deptno1 number) return
comp_cv is
temp_cv cv.comp_cv;
begin
if
deptno1 > 20 then
open temp_cv for select deptno, ename, 1.25*(sal+nvl(comm,0))
compensation
from emp where deptno = deptno1;
else
open temp_cv for select deptno, ename, 1.15*(sal+nvl(comm,0))
compensation
from emp where deptno = deptno1;
end
if;
return temp_cv;
end;
END;
15. Can u have more than one layout in report?
Yes. Is possible to have more than one layout in a report by using the
additional layout
option in the layout editor.
16. Can u run the report with out a parameter form?
Yes it is possible to run the report with out
parameter form by setting the PARAM value to Null
17. What is the lock
option in reports layout?
By using the lock option we cannot move the
fields in the layout editor outside the frame. This is useful for maintaining
the fields.
18. What is Flex?
Flex is the property of moving the related
fields together by setting the flex property on.
19. What is default
Unit of Measurement in Report?
Inch.
20. How many types of
Parameters are available in Reports?
There are two types of Parameters available
in Reports One is System Parameter
and another is User Parameter.
Parameters
can be used to:
• Restrict values in a WHERE clause SELECT
NAME, SALES_REP_ID FROM S_CUSTOMER WHERE ID =User Parameters<a value>
• Substitute any part of select statement
SELECT NAME, SALES_REP_ID FROM S_CUSTOMER
<a where clause>
• Substitute a single column or expression
SELECT <a column/expression> FROM S_CUSTOMER
There are two ways to reference parameters
in a query:
• Use a bind reference.
• Use a lexical reference.
21. What are bind variables?
Variable that is used to replace a single value in SQL or PL/SQL,
such as a character string, number, or date.
Specifically, bind references may be used to replace expressions in
SELECT, WHERE, GROUP BY, ORDER BY, HAVING, CONNECT BY, and START WITH clauses
of queries. Bind references may not be
referenced in FROM clauses or in place of reserved words or clauses.
A bind reference replaces a single value or expression. To create a
bind reference in a query, prefix the parameter name with a colon (:). If the
parameter object does not exist, Report Builder automatically creates it for
you and displays a message. In this case, the parameter default datatype is
Character, not Number.
22. Difference between
Bind and Lexical parameters?
BIND
VARIABLE:
-- Are used to replace a
single value in sql, pl/sql
-- Bind variable may be used to replace
expressions in select, where, group, order
by, having, connect by, start with cause of queries.
-- Bind reference may not be referenced in
FROM clause (or) in place of reserved words
or clauses.
LEXICAL
REFERENCE:
-- You can use lexical reference to replace
the clauses appearing AFTER select,
from, group by,
having, connect by, start with.
-- You can’t make lexical
reference in a pl/sql statement.
23. Which Procedures displays message number and
text that you specify?
SRW.MESSAGE: This procedure displays a message with the message number
and text that you specify. The message
is displayed in the format below. After
the message is raised and you accept it, the report execution will continue.
24. What are lexical
parameters?
You can define lexical parameters in your reports. Lexical parameters
can dynamically replace clauses in the Select statement in the data model and
even the whole select statement=
A lexical reference replaces any part of a SELECT statement, such as
column names, the FROM clause, the WHERE clause, the ORDER BY clause.
To create a lexical reference in a query, prefix the parameter name
with an ampersand (&).
If the parameter object does not exist, Report Builder does not
create. You must always create the parameter for a lexical reference in the
Object Navigator.
Using Lexical References: Use a lexical reference to replace any
clause in a SELECT statement, or even replace the entire statement.
Examples
• The following statements use lexical references to substitute
parts of the query
at run time.
SELECT NAME, SALES_REP_ID FROM S_CUSTOMER &where_clause
• To specify a WHERE clause, ORDER BY clause, or both at run time
(as two separate parameters).
SELECT NAME, SALES_REP_ID FROM S_CUSTOMER &where_clause1,
&where_clause2
• To specify a WHERE clause, ORDER BY, or both clause at run time
(as one parameter).
SELECT NAME, SALES_REP_ID FROM S_CUSTOMER &where_clause
• To specify two column names and the table name(s) at run time:
SELECT &P_CUSTNAME CUST, &P_SALESREP REP FROM &P_TABLE
Note: When you use lexical references in the SELECT list, you must,
at run time, specify the same number of items of the correct datatype, as
defined in the Data Model.

Report?
Run_Product.
26. Can you pass runtime parameters from reports to
a Graphics display?
