😀 .... what I concern is how many rows were updated.

Anyway, thanks for your interest!

@jack-2: My English is not so well, so I am sorry if I may not be able to understand all you talked.

I have understood it as following:

TABLE DEMO(ID, Name, BeModified)

BeModified...

Because I am doing something like an audit action.

It is exactly what I need. Thanks for your helping!
