Hi,
I want to archive(take a backup and keep it in new db) records of the year 1999 and I want to delete them from the main prodcution database. Please tell me how can I do this.
Can I take the backup of records only? or I have to take the backup of whole Database?
Thanks a lot,
Venki
Thank You

Backups are of a complete database or filegroup.

I would suggest creating the table(s) in the new database and, if on the same server, select the rows from the original table(s) into the new table(s) and then do delete from the original tables where exists (Select 1 from new_table where old_table.primary_key = new_table.primary_key.

Replication is definitely not the tool for what you want.

Select into and then deleting is an option but beware to fire these queries if the number of records in your table is huge. Delete might take ages.

Can you answer these questions:

How many records do you have in total?

How many records you want archive?

Jack Corbett already suggested the correct solution. If the deletes are huge, then you need to write a loop to do the deletes in groups of 10 or 20,000 rows at a time.

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.
