不带任何日期列的oracle表的按日期排序

Question

I have a table with a million rows in oracle. But it doesn't have any date column. Is it still possible that I can sort the rows based on the date they were created on ?

Answer 1

ORA_ROWSCN seems to be what you are looking for. Note that it has some conditions. See here for details.

Answer 2

No, you can't. The closest you can get is with ORA_ROWSCN , but unless you have row dependencies enabled that wll reflect changes at block level rather than row level, and if rows have been updated it will refer to that time not the original row insertion time.
