I know I am a little late. From my experience with Oracle Database: ORACLE MYSQL(equivalent) ------------------------------------------------------------------- DATABASE MYSQL INSTALLATION SCHEMA DATABASE
So in Oracle a Database is an instance running on an Oracle installation, While with MySQL you need different installations to have different instances(mysqld). In my opinion Oracle naming approach is more correct, if you consider a Database as a RDBMS, anyway, MYSQL IS GREAT! Aloha!

In your two examples: SELECT * FROM server.sales.schema.product; SELECT * FROM server.product.schema.product; I'm a bit tired, so maybe I'm not seeing it, but what goes in the schema place holder? -Thufir -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED] "Questo messaggio ed ogni suo allegato sono confidenziali e possono essere riservati o, comunque, protetti dall'essere diffusi.
