How to backup certain tables in oracle?

Question

I want to continue working on oracle db from home and I need certain tables I created. How do I back them up then restore them?

Solution 1

Completely agree with Sathya. One thing to note -- rather than reading the manual, you can issue "help=Y" to the imp/exp command. To wit:

exp help=y
imp help=y

This will show you the most common parameters you can use, and also show you the default values for each parameter.

Solution 2

Quick & easy way - use Oracle's exp & imp tools

To export them:

exp scott/tiger file=emp.dmp tables=(emp,dept)

Transfer the dmp file to your destination & then to import them:

imp scott/tiger file=emp.dmp fromuser=scott touser=scott tables=(emp,dept)

We're going to need more information. Do you want to transfer the tables electronically? What are your home and not-home environments like? Does the home copy need to be synced back in with the not-home copy?

I'd suggest asking on serverfault.com

You probably just need to use the export tool from the command line. But you need to read the manual on this as it's not 100% export and then import at home.

there is a limitation in that the data has to be imported back to the same tablespace there's no such limitation - atleast not on "regular" tables. It will cause a problem on Partitioned Tables.
