Tom,
I completely agree with your point. It is one of those semantic
issues that always seems to cause so many problems ('Do what I meant, not
what I said'). So, Yechiel, did you mean move as in migrate or move as in
recreation of the row?

Dan,
I think there is a difference between "migrated" and "moved".
Migrated in my mind refers to a split row - because an update could not fit
in the same block as the record.
Moved in my mind means deleted and re-created, or performed because of an
"Alter Table {} Move Tablespace" command.

Actually, the rowid will not change when a row is migrated. The original
rowid is preserved (for indexing purposes) with a pointer to the new row.
The rowid referenced by functions will be the original rowid.
I performed a test about a year ago that covered this scenario. I found that
when you read a row and extract the rowid, the rowid was always the
original, even if the row had migrated. In looking at the block dump, I
could see the pointer to the new location, but that rowid was not 'visible'
to the query.
Rowids should change if you recreate the table (export/import or
copy/rename). I presume the 9i online table redefinition will do the same
thing, but I have not tried it...yet

When the row is moved to another block.
