Oracle Reports

Oracle Reports is tool for developing, displaying andprinting production quality reports. It is designed for

application developers who are familiar with SQL and

PL/SQL. Following types of reports can be created

Basic ConceptsBasic Concepts

There are 3 steps to building a report with Oracle

reports

Create a new report definition Define the data model ( choose the data,

relationships and calculations which you will use to

produce the report output.

Specify the layout. You can use the default, custom ifdesired or create your own layout.

Data ModelData Model

To specify the data for a report, define a data model.

A data model consists of all or some of the following

data definition objects.

Queries

Queries are SQL select statement that fetch data

from database.

External Query

Oracle Reports

Data ModelData Model

It is the name of the external query stored in a

database or file

Groups

Groups determine the hierarchy of the dataappearing in a report and are primarily used to create

breaks

Cross product Group

A cross product group is generally used to create

matrix reports

Columns

Columns contain the data values for a report. Defaultreport columns corresponds to the table columnsincluded in each querys select list.

Summary Column

Summary Column is a computation that is performedon all the records of a single column. Eg sum of allthe salaries. Oracle reports has the Average, Count,First, Last, Maximum and Minimum as summary.

Formula Columns

A formula is a computation performed on a singlerecord spanning one or more columns.

Placeholder Columns

A place holder is a dummy column for which you can

conditionally set the data type and value via PL/SQL

or a user exit.

Parameters

Parameters are variables fr your report that enables

you to change the selection criteria at runtime.These

parameters can be referenced elsewhere in the

report such as PL/SQL constructs providing

conditional logic for the report.

Datalinks

Data links are used to establish parent-child

relationships between queries and groups via column

matching.This data link is converted into a SQL

clause when the report is executed.

Oracle Reports

Datalinks can establish two relationships

Between one querys column and another querys

column Between one querys group and another querys

group ( this is useful when you want the child query

to know about its parents data)

Layout EditorLayout Editor

Layout editor is used to specify the Layout for the

report. It uses following objects.

Repeating Frames

Repeating frames act as a placeholders for groupsand presents rows of data retrieved for the database.

Repeating frames repeat as often as the data is

retrieved.

FramesFrames surround other layout objects, enabling you

to control multiple objects simultaneously.

Oracle Reports

Fields

Fields act as place holders for columns. 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.

Boilerplate

Boilerplate consists of text and graphics that appear

in a report each time it is run. E.g. Label for fields

Fields, BoilerplatesFields, Boilerplates

Anchors

Anchors fasten an edge of one object to an edge of

another object,ensuring that they maintain their

relative position.

Layout RegionsLayout Regions

Header

The report header pages appear once at the

beginning of each report on a set of separate

pages.They contain text, graphics, data andcomputations.

Main (Body/Margin)

The body pages appear between the header and the

trailer pages, and are the bulk of the report. Eachphysical page in this section consists of a body

and a margin. The body contains the text,

graphics data and computation.

Report ModesReport Modes

Confine Mode

Confine mode restricts the movement of the fields

outside the borders of its repeating frame.

Flex Mode

Flex mode resizes all the parent objects when the

child object bumps into a parent border.

Report triggers enable you to execute PL/SQL

functions at specific times during the execution and

formatting of report.

SRW PackageSRW Package

SRW package is a collection of PL/SQL constructs,

which include many functions, procedures and

exceptions that you can reference in your report.

This procedure calls the user exit named in

user_exit_string. It is useful when you want to pass

control to a 3GL program during a report's execution.

Syntax: SRW.USER_EXIT (user_exit_string CHAR).

Example: SRW.USER_EXIT(FND, INIT)
