Yes, but if you need it then you have a bad application implementation.

Please read and follow OraFAQ Forum Guide, especially "How to format your post?" section.
Make sure that lines of code do not exceed 80 characters when you format. Use the "Preview Message" button.
Please always post your Oracle version (4 decimals).

Please give a description of B (an ouput is NOT a description).
Please explain how you want to fill B with A values during insert.

If it would be a real case, I'd say change your implementation, it is bad.
As this is a homework, I say: post what you already tried.

Regards
Michel

This is too easy if you read about triggers. Read it.
