How to check if index was updated?

Got a query from my developers, they are trying to use the
"update xxx set row " syntax to modify a row using a record.

How would I verify that pk index will not get updated if only non
indexed columns were changed in the record?

is there an easy way? btw this is on 10104.

TIA
