Are the other fields in the update statement actually changing the

Hi Scott,
Indeed, only the BDB and InnoDB storage engines support referential
integrity. If you accidentally create the table as MyISAM, there is
no error, though -- the constraints serve as a comment.
Replication is storage-engine independent, so you shouldn't have a
problem with that.
As I have been reading, it appears that the InnoDB Storage Engine
supports PK/FK relationships. And that the MyISAM does not. But I cannot
verify that.
That is correct.

I didn't write the codebase for MySQL, so it's pointless to tell me
that it's useless to be able to create a foreign key on a MyISAM
table. I agree that it's useless, however, it's possible, which is
why I put it in there -- as a caveat.
The use is that apparently in future versions MyISAM will

depending on the service).

No, I don't have that. There's about 5-10% change in employees ids from
every year, and no one took any interest in this system before I got it

Would it help to have one??

OK. No problem. We can hopefully still make this work with a temporary

The SQL will look something like this:

If you use ALTER TABLE on a MyISAM table, all non-unique
