Oracle report builder

 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, `&parameter_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.

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.
