Re: RPGLESQL ROW CHANGE TOKEN

Sure, a column with ROW CHANGE TIMESTAMP has the best benefits, we use it
all the time. But when an existing table has no ROW CHANGE TIMESTAMP and if
it cannot be extended for some reason, then the TOKEN can be helpful.

We use the GENERATED ALWAYS ... ROW CHANGE TIMESTAMP for the same
purpose -- at UPDATE time to insure that a row hasn't already been changed
by another process since the last time the current process retrieved the
row content. Therefore, we get two benefits from using a timestamp
instead of a token.
