get the name of the update by query column

Hello
How can I get the name of the update by request column
I need to insert the name of the column changed in a query to update a history table by using a trigger created on the main table.
How can I get the update column name in this trigger

Thanks in advance

Thanks for the reply, but wouldn't be an additional burden to compare all values
what I was looking for was a direct request or variable system oracle for such use

Comparing the old and new values wud tell me which column is updated then how to get the anme of column

for example update test set emp_name = "Sicard' where emp_pos = 'President ';

now I want to insert 'emp_name' in the table test_hist as follows
==========================================
name colmn = old value = new value = update the = updated by
emp_test = notsapan = sapan = sysdate = syscontext_user

Well, since you have a typical requirement (for which Oracle doesn't have a built-in support), you will need to compare the old and new values, and insert the name of the column "manually" in the logging table.

Little extra processing is indeed (CPU cycles) to find the modified column.
