Instant Row Delete in Oracle APEX Using JavaScript and PL/SQL

This Oracle APEX Tutorial helps you to add row delete functionality in a classic report or interactive report. Most of the time, we have to need the same implementation in our oracle apex project. Let's take a simple example that we need to delete an unimportant row from the report. So I will provide the simple and easiest method to achieve it.

Please follow the steps listed below

Step 1:- Create a classic or interactive report with the following SQL query and create also a page item. You can match the following screenshot.



SELECT
EMPNO,ENAME,JOB,SAL,
DEPTNO,
'<a href="#" class="demo" onclick="ok(this)" data-index='||EMPNO||'>
 <button type="button" class="t-Button t-Button--danger t-Button--simple t-Button--stretch">
Delete</button></a>' AS TRASH
FROM
NEW_EMPLOYEES_TALE

As you see in the above code, I am using an anchor tag to create a link in the report and pass the table primary key value in the data-index also I am calling a javascript function on that link, as usual, you can create a report with your database table and pass the table unique value in the data-index. (Note:-Your last column display with full HTML so please go with your column property and off  escape special characters property )

Step 2:- Now I am creating a javascript function that I am calling on the link. Copy the below javascript code and paste it into your page Function and Global Variable Declaration section. You can match the following screen.


function ok(elem){          
    var a=$(elem).data('index');
    console.log($(elem).data('index'));
    apex.item( "P37_EMPNO" ).setValue( a, null, true );//Pass your page item name
(for Ex- EP37_EMPNO)
  }

Step 3:- Now you have to create a click dynamic action to delete a row using PL/SQL and refresh the report. You can match the following screen.

Event:- Click
Selection Type:- Jquery Selector
Jquery Selector:- .demo(Pass class name with a dot)
Event Scope:- Dynamic


True Action:- Execute PL/SQL Code
PL/SQL:- BEGIN
DELETE FROM NEW_EMPLOYEES_TALE 
WHERE EMPNO=:P37_EMPNO(Pass your Page Item);
EXCEPTION WHEN OTHERS THEN
NULL;
END;
Items to Submit:- P37_EMPNO(Pass your page item)

Create one more true action Refresh Region.


Action:-Refresh
Selection Type:- Region
Region:- (Pass your Region)
