Multi-select List Item in Oracle APEX | Checkbox Group

In my previous post, I explained how to use Shuttle Item. In this post, I will explain how to use another multi-select item Checkbox Group. 

In Oracle APEX, Checkbox Group displays multiple values as checkboxes and enables end-user to select multiple values. Like the Shuttle item, the Checkbox Group also stores values of checked boxes in a colon-delimited string. We need to provide a list of values for values displayed as checkboxes.  

How to create a Checkbox Group? 

  1. Create a VARCHAR2 column having a large size as it stores a colon-delimited string.
  2. Navigate to an APEX page and create a page item in a region that is based on the database table.
  3. Change its type to "Checkbox Group".
  4. Go to the "List of Values" section in the property section and select the list of values type. Here I selected "Static Values". 
  5. Click on the "Static Values" and a popup will open. Add Display Value and Return Value in this popup as shown below. 
  6. Enter the number of layout columns used to display checkboxes in the "Number of Columns" property. For example, a value of 3 would display three columns of checkboxes. The default value is 1 which means all the checkboxes would display in one column.
  7. Save the changes and run the page.

The values of these selected checkboxes are stored as a colon-delimited string. Refer to my previous post where I explained how to use colon-delimited values in SQL query and PL/SQL block. 

Checkbox Group is useful when there is a few list of values available to select from. For more list of values, Checkbox Group is not a good option from a UI perspective as there are lots of checkboxes on the form.

Sorting Order in Oracle APEX Classic Report

Image
In APEX, the sorting option for a classic report is divided into two aspects:  How records will be sorted when the report first renders? Whether the end-user can change the sort order interactively by clicking the column header. A classic report can be developed using either the static query or the dynamic query and the sorting behavior is different for both options. First, we will see the sorting behavior for the report based on the static query.  The below classic report is based on the static query and displays all the records of the EMP_DUP table. For this blog, I created EMP_DUP which is the same as the EMP table but contains duplicate records. The sorting aspects for this report are determined by the properties in each column's  sorting  section. The below image shows the  sorting  section for  JOB. The Default Sequence  property determines the initial sort order. Each column that participates in the initial sort order will have a unique sequence number that will determine

OTP based Authentication in Oracle APEX using Twilio

Image
Recently, a new requirement came up to implement One Time Password (OTP) based authentication in Oracle APEX. In this, the user will enter his mobile number on the login page and will receive an OTP via SMS. The user will then enter the OTP on the login page and be able to authenticate himself in the APEX app.  When I started working on this requirement, first I identified all the steps that I need to implement for the solution.  Below are the steps that I followed: 1. Generate the OTP and temporarily store it in a database table. 2. Send the generated OTP to the user by integrating REST API to send the SMS 3. Validate the user entered OTP against the OTP that is stored in the table and authenticate the user. 4. Create a Custom Authentication Scheme. 5. Modify the login page. Let's understand each step in more detail. Step 1:  Generate the OTP and temporarily store it in a database table.  First, create a table to temporarily store the OTP for the validation. Here I created a si
