If you are working as developer/DBA probably you are quite often asked to migrate some rows from one database to another – usually people reference to the rows as “metadata” rows. Rows that driving your business !
If you need to prepare such rows for migrations there are a lot of methods to do it
just copy the rows using database link from one database to another
export/import the rows using tools like expdp/impdp
prepare manually scripts with INSERT statements
I would like to focus on the last method. It’s very popular to keep metadata in some files as number of INSERTs for backup/migrations/versioning etc.
