- Well folks, I know that Ingres had a similar facility that listed transaction
- numbers, times, table, rowid (called a tid in ingres) and even before and
- after values !
-
- This was using Ingres v5 under VMS back in late 1987.
-
- This let you then decide to roll back to a specific time or transaction number.
-
- What about it, Oracle ?
