Oracle Application Express shows deleted data from oracle table

Question

I have deleted a row from Oracle

delete from student where gr_number = 51777;

In Oracle Application Express form that contain interactive report, fetching data from student it shows deleted row. I also check by using SQL commands from Oracle Application Express and it shows deleted row again

select * from student where gr_number = 51777;

Please tell why Oracle Application Express displays deleted record from Oracle table.

I am using Oracle Application Express 18.2

Answer 1

Because you didn't COMMIT after issuing DELETE.
