INSERT INTO NEW_TABLE (select old.x,sum(old.y) from OLD_TABLE old group by
old.a)
on duplicate key
update
I think that you need to select old.a otherwise you cannot group by it.

I guess I don't understand the issue. Do you want to display the text
equivalent of the occupation code in the language associated with the person
in the database, or in the putative language used by the web browser?

No, it just takes a little indirection to represent this in a properly
normalized fashion. What you need is:

Maybe check out file system consistency, check logs.
Yes. create new partition, and move /var/lib/mysql/ to new partion.
It may avoids OS dependent file problem.
