Hi Experts,

What's the best way to recover a single table from the backup? Which tool is recommended for this in Oracle 10g/11g? Please share your experience/knowledge on this.


Regards,
Richard

>What's the best way to recover a single table from the backup?
It depends upon what/how backup was taken.
If RMAN backup, then RMAN restore.

You can't recover one table from a backup! The rules of a relational database forbid it, because to do so would compromise the transactional integrity. You can try to replace it with a copy taken from an export, or you can try to back-out changes with undo-based flashback, but there is no guarantee that these will work.

A) If you have export backup, then you can import the table.

B) If you have rman backup or OS cold/hot backup you would need to restore to another server/database, export the table and import to you db.

WARNING: You will only have the table data until the time the backup was taken plus (except for export backup) any archive logs you could apply .

PS: Have you checked the RECYCLEBIN? Maybe i's still there...

Who said the table has been lost? Who said it has been dropped?
The question is:

A) If you have export backup, then you can import the table.

An import is not a recovery.

IF it is through RMAN Please Check the Below links
how-to-recover-a-table-using-rman-backup

recovering-a-particular-table

And IF we don`t have the complete information ,
1)We can ask the OP for more specific details...
2)) We can post/send Our replies/suggestions/thoughts BY assuming any of the possible reasons.is n`t it?

OK, so what do you think the following answer:
"You don't need to recover the table is still there."
As per your post ("We can post/send Our replies/suggestions/thoughts BY assuming any of the possible reasons") it is a valid answer, but just a silly one given original question.

Michel

I post that now just to show you that your sentence just leads to silly answer and we currently get more and more of this kind of answer because posters assume some things they have not to assume but should ask OP for precisions if they think the question lacks of them.

Michel

Due to the fact the the only information provided by the OP is "recover a single table" and the two possibilities in which this may occur are: a) Table data was corrupted by bad DML or b) Table was dropped, It is valid to provide answers based on assumptions that any of these two situation may have occured.

And I agree with ramoradba in the sense that if the answers do not satisfy the OP, then he/she should provide more specific details or explanation.

NO Now i totally disagree with you...

It is a best approach to ask the OP.

And i prefer "Don`t criticise any User" ./fa/1579/0/
If you re read the discussion between Michel and Me i hope you may realise . And seniors are here to Guide Us,Answers/post with the assumptions may miss lead the OP.

Thank you

Hi sriram,

I don't know why you beleive I was critisizing anyone, but if someone took offense it was unintentional.

If you are refering to my "PS" to michel, just a joke, he dislikes the use of smilies and seems to enjoy removing them from postings.

On the issue of this thread, if we can cover any angle related to a question, why not? sometimes the information posted will provide ideas to the OP and help him/her focus on the actual issue trying to be solved.

Well, maybe we should shut down this thread and move on.

(TGIF) Have a great weekend!
PS: Where do you get those nice smilies that don't appear on the edit window?
