first of all, how would you know?
Lots of manual labour 
This is why I’m trying to build an application that will do the thinking for us.
helps?
I’ll have to do some testing r937
Small example…
If I have a timestamp column for last edited of that row, and as you say…
MySQL notices this and does not update it
…then the timestamp will keep the old date and not update because nothing has changed?
I was just reading a possible solution if this is not the case using
CASE WHEN ??? <>
