Overview

Interactive Reporting Regions enable end users to customize reports. Users can alter the layout of report data by choosing the columns they are interested in, applying filters, highlighting, and sorting. They can also define breaks, aggregations, different charts, and their own computations. Users can create multiple variations of the report and save them as named reports and download to various file formats including comma-delimited file (CSV) format, Microsoft Excel (XLS) format, Adobe Portable Document Format (PDF), and Microsoft Word Rich Text Format (RTF). For further information, click on help and search on Interactive Reports.

Another new feature shown in this tutorial is Application Date Format. You can define a date format that will be used throughout your application. This date format will be used to alter the NLS_DATE_FORMAT database session setting prior to showing or submitting any page within the application. This format is used by all reports showing dates and is also picked up by form items of type 'Date Picker (use Application Date Format)'. This can be set using:

  1. Application Builder > Application Builder Defaults (under Tasks): These are specific to a Workspace, not a developer, and will be used as the default when using the create application wizard.
  2. Application Builder > Create Application Wizard > Attributes page
  3. Application Builder > Your Application > Shared Components > Edit Globalization Attributes

This tutorial shows the developer how to create and customize an Interactive Report for an end user.

Manipulating Your Interactive Report

Now that the Interactive Report has been created, you can manipulate the report in many ways. In this section, only some of them are discussed. You can review more on this topic in the OBE Using Interactive Report Regions with Oracle Application Express 3.1. Perform the following steps:

1.

You can search for values. Enter John in the search bar and click Go.

 

2.

Notice that only the rows where john is found are listed. A filter was also created above the report data.

 

3.

To hide a column, you can select the column header link and then click the hide icon column.

 

4.

Notice that the column no longer appears in the report. Note: You can show the column again by clicking Select Columns from the Actions menu (discussed later in this tutorial).

 

5.

To sort on a column, click the header you want to sort on and select the Sort Ascending or Sort Descending icon. Select the Last Name column and click the Sort Ascending icon.

 

6.

The report is now sorted on Last Name.

 

7.

You can delete the filter you created earlier. Click the red X next to the filter.

 

8.

You can create a control break on a column. Select the Actions menu pulldown and select Control Break.

 

9.

You want to break on the Department ID. Select Department ID from the list of columns and click Apply.

 

10.

The control break was created. Notice that the column was eliminated in the list and now appears before each breakpoint in the report.

 

11.

You can also highlight a particular cell or row in the report based on some criteria. Click the Actions menu and select Highlight.

 

12.

You want to highlight the row of an employee if their salary is higher than $10,000. Enter Top Tier Salary for the Name, make sure Enabled is set to Yes, and Highlight Type is set to Row. Select [red] for Background color and [blue] for Text color. Under Highlight Condition, select Salary for the Column, select > for the Operator and 10000 for the Expression and click Apply.

 

13.

Notice that a highlight rule was created at the top of the report and the rows that met the criteria are highlighted.

 

14.

You can create a computed column. In this case, you will create a column to show the monthly salary for each employee. Click the Actions menu and then select Compute.

 

15.

Enter Monthly Salary for the column header and select the down arrow for Format Mask and select the $5,234.10 from the list.

 

16.

From the list of Columns scroll down and select Salary. Notice that the letter corresponding to the column appears in the computation area. This is the column alias. Click / in the keypad and then enter 12 after the / in the computation area. Then click Apply.

 

17.

Notice that the computed column now appears in the report.

 

18.

You can also aggregate a particular column. Click the Actions menu and select Aggregate.

 

19.

You want to total the Monthly Salary column. Select Sum for the Function and **Monthly Salary (the ** indicates that the column is a computed column) for the Column. Then click Apply.

 

20.

You now see a total salary for each department. Note: the aggregated column inherits any formatting from the base column.

 

21.

You can save all the customization you have made to this report. Click the Actions menu and select Save Report.

 

22.

Enter My Report for the Name and click Apply. Note: Save as Named Report is available to all authenticated end users (when saving reports is enabled for the region).  The report settings are displayed as a tab above the report, with the name you provide, and is visible *only * for the APP_USER who saved it. Save as Default Report Settings is only available to developers.  These settings are applied to anyone who comes to the page for the first time in a session.

 

23.

Notice that you now see a tab with all the display changes you made. This customized view will be available each time you login.

 

24.

You can view a record in the report by clicking the icon before the row you want to view.

 

25.

The record is displayed.

 

26.

To navigate back to the report, click Report View.
