Is it normal for MySQL to not update fields that are already identical?
I am talking about an INNER JOIN UPDATE, when copying from table A over
table B.
My count did not match at the first run and when I did the second run, I
go a zero rows updated...

Hello.
If you set a column to the value it currently has, MySQL notices this
and does not update it. Perhaps it is the answer on your question. See:
