Home -> Community -> Mailing Lists -> Oracle-L -> RE: move some records of some tables
Murat
Congratulations on moving the tables out of the SYSTEM tablespace. That is how most of us become better DBAs -- by doing it wrong first. I've learned those lessons myself. Now I read this list and learn from the mistakes of others.
If the tables you are moving data into already contain data, you need to decide how to make sure you don't end up with duplicate data. If each table has a primary key, this will prevent duplicate data, but then your import will fail. If the data overlaps and you want the data from the other instance to be loaded, you can first delete the data that overlaps and then import the data.

Murat - The best method depends on several circumstances such as how much data is involved. The simplest method if you have two Oracle instances is export/import.
Is the username the same on both instances? Yes.
Are there differences between the instances such as NLS character sets? No, they're the same.
Are both instances the same Oracle version? Yes.
Are you moving all the tables for the user? No.
All the rows in each table?
No.
Do those tables already exist on the other instance? Yes.
If yes, do the tables already contain data? Yes.
And... Another difference is : Original tables are on the SYSTEM tablesapce. This was made by mistake. Tables I'll import to are on another tablespace.
If you are not familiar with the Oracle export/import utilities, a good
start is to look at this link.

Thanks, I'll look at it.

Hi,
what's the best method to move some rows of some tables of a user from one database to another database on another server? I need a step by step document to achieve this.
Thanks,
Murat
