How do you confirm an UPDATE?

Short answer. SELECT the row with the same WHERE.

Why SELECT before changing?

To see which rows the WHERE matches.

Remember

SELECT before the change
SELECT again after it

Your update ran. But did it change the right row? Run select with the same where. Aman shows eighty, so the change worked. Select before the change. Select again after it.
