Neither, really. You can qualify a table with the database name to operate on tables in multiple databases on the same host.
Federated is a way of accessing a table's data from a remote instance of mysql. -----Original Message----- From: winterb...@gmail.com [mailto:winterb...@gmail.com] On Behalf Of Wellington Fan Sent: Friday, October 08, 2010 9:52 AM To: mysql@lists.mysql.com Subject: Federated Tables versus Views Hello All, What should I consider when trying to choose between a Federated table and a View when I have one table's data that I'd like to be available in other databases on the same host. My view definition would be something like: CREATE [some options] VIEW [this_db].[this_view] AS SELECT [some_db].[some_table].* FROM [some_db].[some_table].* Are there performance gains to be had, one against the other? Security concerns? Replication gotchas? Thanks! This message contains confidential information and is intended only for the individual named.
