I\'m looking at a client application which retrieves several columns including ROWID
, and
later uses ROWID
to identify rows it needs to update:
"From Oracle 8 the ROWID
format and size changed from 8 to 10 bytes. Note that ROWID
's will change when you reorganize or export/import a table. In case of a partitioned table, it also changes if the row migrates from a partition to another one during an UPDATE
."

I'd say no. This could be safe if for instance the application stores ROWID
temporarily(say generating a list of select-able items, each identified with ROWID
, but the list is routinely regenerated and not stored). But if ROWID
is used in any persistent way it's not safe.
