Oracle Reports Builder: Overview and Usage
Oracle Reports Builder is a component of Oracle Reports, a powerful reporting tool used to design and generate reports based on data stored in Oracle databases. It is widely used in enterprise environments to create both simple reports (such as tabular data) and complex reports (like grouped, summary, or matrix reports). Oracle Reports Builder allows developers to build reports in different formats, such as PDF, HTML, XML, RTF, and Excel.
# Key Features of Oracle Reports Builder:
- Graphical User Interface (GUI): The tool provides a visual interface for designing reports.
- Multiple Layouts: Supports different types of report layouts like tabular, matrix, master-detail, and more.
- Data Source Connectivity: It can connect to multiple data sources like Oracle databases, SQL queries, PL/SQL code, text files, and XML files.
- Formatting Options: You can customize the layout of the report, including headers, footers, data grouping, page breaks, and styling.
- Multilingual Support: Oracle Reports supports various languages and character sets, making it ideal for global applications.
- Integration with Oracle Forms: Oracle Reports Builder works well in environments where Oracle Forms is used, allowing reports to be generated based on the data captured through Forms.
Key Components of Oracle Reports Builder
1. Data Model:
- The Data Model defines the structure of the data in the report. It includes Queries, Groups, and Columns.
- You can use SQL queries, PL/SQL blocks, and Functions to retrieve data from the database.
- Groups are used for organizing data, such as creating master-detail relationships (e.g., customers and their orders).
2. Layout Model:
- The Layout Model controls how the data is presented in the report (e.g., tables, charts, and text).
- You can customize the layout using report items like frames, repeating frames, fields, boilerplate text, and graphs.
3. Triggers:
- Triggers in Oracle Reports are similar to those in Oracle Forms but apply to report-level events.
- You can use PL/SQL triggers to manipulate data, handle exceptions, or control how the report behaves when certain events occur (e.g., before/after printing a page, before/after querying data).
4. Parameter Form:
- You can design a Parameter Form to allow users to input values before generating a report, such as date ranges, customer IDs, or product types.
5. Flexibility with Output Formats:
- Oracle Reports supports different output formats such as PDF, HTML, XML, Excel, and RTF. This makes it easy to integrate reports into web applications or print them as documents.
6. Preview and Runtime:
- Reports can be previewed within the Reports Builder before final deployment, ensuring the layout and data are correct.
- Once the report is compiled into an `.rdf` (Report Definition File) or `.rep` (Report Runtime File), it can be deployed and run through Oracle Reports Server, Oracle Forms, or integrated into an application.
Steps to Create a Report Using Oracle Reports Builder
# 1. Open Oracle Reports Builder
- Launch Oracle Reports Builder from your Oracle Developer Suite.
- Connect to the database using your credentials (username, password, and database connection).
# 2. Create a New Report
- Use the Report Wizard to quickly create a new report or start from scratch.
- File > New > Report: This will launch the Report Wizard, which guides you through the process of selecting data, layout, and styling.
# 3. Define the Data Model
- Use the Data Wizard to define the source of the report’s data. This typically involves writing SQL queries or selecting tables/views from the database.
- Example: Write a SQL query to retrieve data for your report (e.g., fetching customer orders).
```sql
SELECT customer_id, order_id, product_name, order_date, total_amount
FROM orders
WHERE order_date BETWEEN :start_date AND :end_date; ```
- Bind variables (like `:start_date` and `:end_date`) can be used to pass parameters from the user.
# 4. Design the Layout
- After the data model is set, define the report’s layout using the Layout Wizard.
- Choose the layout type: Tabular, Matrix, Master-Detail, or Form.
- Define the appearance, such as font, colors, alignment, and grouping levels.
- Place repeating frames, fields, headings, and other items to structure the output.
# 5. Customize the Report
- You can modify the layout manually after using the wizard. Use the Object Navigator and Layout Model views to:
- Reposition elements.
- Add headers, footers, images (like company logos), or charts.
- Apply conditional formatting (for example, highlight values above a certain threshold).
- Insert boilerplate text for static content like titles and labels.
# 6. Add Parameters and Triggers
- Parameters: Create user input parameters (e.g., dates, customer IDs) to make the report dynamic.
- You can add parameter forms where users can enter these values before running the report.
- Triggers: Add triggers like `Before Report`, `After Report`, `Before Parameter Form`, and `After Parameter Form` to control the report generation process.
```plsql
function BeforeReport return boolean is
begin
-- Add your business logic here
return (TRUE);
end;
```
# 7. Preview the Report
- Use the Previewer to view the output before deployment.
- Modify the layout or query if necessary to ensure it matches the expected result.
# 8. Compile and Save the Report
- Save the report as `.rdf` (for development purposes) or compile it into `.rep` for production deployment.
- Reports can also be exported to formats like PDF or Excel for distribution.
# 9. Deploy the Report
- Reports can be deployed via the Oracle Reports Server or integrated with Oracle Forms or web applications.
- Schedule reports to run at specific times or on demand using Oracle Reports Services.

In Oracle Report
Builder, a **lexical parameter** is a specific type of parameter that allows
you to customize SQL queries at runtime without modifying the original report's
SQL statement. Lexical parameters enable the report developer to create more
dynamic and flexible reports by injecting values into the SQL queries used to
fetch data. Here’s a more detailed explanation of lexical parameters, their
usage, and advantages in Oracle Reports:
### What is a Lexical
Parameter?
- **Definition**: A
lexical parameter is a placeholder in the SQL query that allows for dynamic
substitution of values when the report is executed. Unlike regular report
parameters, which can only be used within the context of the report's data
model, lexical parameters can be used directly in the SQL statements of the
report.
- **Syntax**: Lexical
parameters are typically defined using a special syntax, which consists of an
ampersand (`&`) followed by the parameter name. For example,
`¶meter_name`.
### How to Use Lexical
Parameters
1. **Defining Lexical
Parameters**:
- Lexical parameters are defined in the
report's data model or directly within the SQL query. You can specify them in
the SQL command by including the parameter placeholder.
**Example SQL Statement**:
```sql
SELECT * FROM employees WHERE department_id
= &dept_id;
```
2. **Assigning
Values**:
- When the report is run, Oracle Reports
prompts the user to provide a value for the lexical parameter. This value is
then substituted into the SQL query before execution.
3. **Scope of Use**:
- Lexical parameters can be utilized within
the query definition of a data group or a specific SQL query. They are
particularly useful for creating reports that need to filter or customize data
based on user input or predefined conditions.
### Advantages of
Lexical Parameters
1. **Dynamic Queries**:
They allow for the creation of dynamic SQL queries, enabling users to modify
the query based on input at runtime.
2. **Reusability**:
Lexical parameters enhance the reusability of reports. The same report can be
executed with different filter conditions without needing to change the report
design.
3. **Flexibility**:
They provide greater flexibility in report design by allowing developers to
change how data is queried based on user needs without altering the underlying
report structure.
4. **Reduced
Complexity**: Using lexical parameters can simplify complex reports where
multiple conditions are needed, allowing users to specify only the necessary
filters.
### Example Scenario
Imagine you have a
report that displays employee information filtered by department. Instead of
creating separate reports for each department, you can use a lexical parameter
to dynamically filter the data:
1. **SQL Query**:
```sql
SELECT employee_id, first_name, last_name
FROM
employees
WHERE department_id = &dept_id;
```
2. **User Prompt**:
When the report is executed, the user is
prompted to enter a value for `dept_id`, allowing them to generate the report
for any department without creating multiple versions of the report.
### Considerations
- **Parameter
Initialization**: Ensure that the lexical parameter is initialized properly in
the report, as not providing a value will result in a runtime error.
- **Performance**:
Although they offer flexibility, using too many lexical parameters or complex
queries may impact report performance, so it’s essential to optimize the SQL
query accordingly.
### Conclusion
Lexical parameters in
Oracle Report Builder provide a powerful way to create dynamic reports by
allowing runtime customization of SQL queries. They enhance the flexibility and
usability of reports, enabling users to tailor data retrieval based on specific
criteria without needing to modify the underlying report structure. This makes
them a valuable feature for developers working with Oracle Reports.

(e.g., SQL Query, PL/SQL).
- Columns: You can also view and adjust the
columns that are retrieved from the query by clicking on the Columns node under
your data source in the Object Navigator.
# 5. Add Parameters (If
Necessary)
- If your SQL query
uses bind parameters (like `:dept_id`), you need to define these parameters in
your data model:
- Right-click on Parameters under the Data
Model and select Create.
- Enter the parameter name, data type, and
any default values.
# 6. Preview the Data
Source
- To ensure your data
source works correctly, you can preview the data:

data source you just created.
- Select Preview Data to check if it returns
the expected results.
# 7. Save the Report
- Save your changes by
going to File > Save or Save As and give your report a name.
Example of Creating a Data Source
Let's say you want to
create a report listing employees in a specific department:
1. Open Reports Builder
and create a new report.
2. Create a Data Source
using the following SQL query:
```sql
SELECT employee_id, first_name, last_name
FROM employees
WHERE department_id = :dept_id;
```
3. Define a Parameter
called `dept_id` with a data type of Number.
4. Preview the data to
ensure everything is set up correctly.
Conclusion
Creating a data source
in Oracle Reports Builder involves defining how to retrieve data, whether
through SQL queries, PL/SQL procedures, or database links. By following the
steps outlined above, you can effectively set up a data source to use in your
reports, allowing you to present dynamic and relevant data to end users.
==
In Oracle Reports
Builder, the primary file extension used for reports is:
.rdf
- RDF File: The `.rdf`
(Report Definition File) extension is used for files created in Oracle Reports
Builder. This file contains the complete definition of the report, including
the data model, layout, and other report properties.
Additional File Extensions
In addition to `.rdf`,
you may encounter other related file extensions in the context of Oracle
Reports and Oracle applications:
1. .rdf - Report
Definition File
- Contains the design and layout of the
report.
2. .rep - Report File
- This is a binary file generated from an
RDF file when the report is compiled. It contains the compiled report
definition that can be executed.
3. .xml - XML File
- Used for exporting or saving report
definitions in XML format, which can be useful for integration or migration.
4. .log - Log File
- Generated during the execution of a
report, it contains logs for debugging and error reporting.
Summary
- Main File Extension: .rdf
(Report Definition File)
- Related Extensions: .rep,
.xml, .log
When working with
Oracle Reports Builder, the primary focus will typically be on the `.rdf`
files, which represent your report designs.

Scheduling a report in
Oracle can be done using various tools, depending on your environment and requirements.
One common approach is to use Oracle Enterprise Manager (OEM) or the Oracle
Scheduler in conjunction with Oracle Reports. Below, I’ll provide detailed
steps for both methods: using Oracle Reports with Oracle Scheduler and using
Oracle Enterprise Manager.
Method 1: Scheduling Reports Using Oracle
Scheduler
Oracle Scheduler allows
you to automate the execution of reports at specified intervals. Here are the
steps to schedule a report using Oracle Scheduler:
# Step 1: Create a
PL/SQL Procedure for the Report
First, you need to
create a PL/SQL procedure that executes the report. Here's an example:
```sql
CREATE OR REPLACE
PROCEDURE run_report AS
BEGIN
-- Use the built-in package to run the
report
-- Replace 'your_report.rdf' and parameters
as needed
SUBMIT_REPORT('your_report.rdf',
'your_output_format', 'your_parameter_name=your_parameter_value');
END run_report;
/
```
- Adjust the procedure
to call your report and provide any required parameters.
# Step 2: Create a Job
in Oracle Scheduler
Once the procedure is
ready, create a job in Oracle Scheduler:
1. Connect to SQL*Plus
or another SQL client that connects to your Oracle database.
2. Create a job using
the following SQL:
```sql
BEGIN
DBMS_SCHEDULER.create_job (
job_name => 'RUN_REPORT_JOB',
job_type => 'PLSQL_BLOCK',
job_action => 'BEGIN run_report; END;',
start_date => SYSTIMESTAMP,
repeat_interval => 'FREQ=DAILY; BYHOUR=1; BYMINUTE=0;', --
adjust as needed
enabled => TRUE
);
END;
/
```
- Modify the
`repeat_interval` to define how often you want the job to run (e.g.,
`FREQ=DAILY; BYHOUR=1; BYMINUTE=0;` runs daily at 1:00 AM).
# Step 3: Check
Scheduled Jobs
You can check the
status of your scheduled job using the following query:
```sql
SELECT job_name,
enabled, state
FROM DBA_SCHEDULER_JOBS
WHERE job_name =
'RUN_REPORT_JOB';
```
Method 2: Scheduling Reports Using Oracle
Enterprise Manager (OEM)
Oracle Enterprise
Manager allows you to schedule reports easily through its graphical interface.
# Step 1: Log in to
Oracle Enterprise Manager
1. Open your web
browser and navigate to your Oracle Enterprise Manager URL.
2. Log in with the
necessary credentials.
# Step 2: Navigate to
the Reports Section
1. In the OEM console,
navigate to the Reports section from the main menu.
2. Select the report
you want to schedule.
# Step 3: Schedule the
Report
1. Once you have
selected the report, look for an option to Schedule or Run Now.
2. In the scheduling
options:
- Set the frequency (e.g., daily, weekly,
monthly).
- Specify the start time and duration.
- Choose the output format (PDF, HTML,
etc.).
3. Configure any
required parameters for the report.
# Step 4: Review
Scheduled Reports
1. After scheduling,
you can review your scheduled reports in the Scheduled Reports section of OEM.
2. You may also
configure notifications to alert you when reports are run or if errors occur.
Additional Considerations
- Permissions: Ensure
that the user account executing the report has the necessary permissions to
access the report and any underlying data.
- Error Handling:
Implement error handling in your PL/SQL procedures to log any issues that occur
during report execution.
- Output Management:
Determine how and where you want the report output to be saved (e.g., local
file system, database table, email).
Conclusion
Scheduling a report in
Oracle can be accomplished using Oracle Scheduler or Oracle Enterprise Manager,
depending on your environment. By creating a PL/SQL procedure and setting up a
scheduled job or using the OEM interface, you can automate the generation of
reports to meet your business needs. This ensures that stakeholders receive
timely and relevant information without manual intervention.
