Re: How to get some table entries from backup instance back to production instance

Hi,

I would do this way:
After the first step select the required records into another tables with CREATE TABLE patmp AS SELECT * FROM pa WHERE ...
Move these temporary tables to the prod database by dump and restore and transfer the content into the prod tables with INSERT INTO pa SELECT * FROM patmp.
Done.

Sándor Daku
