(1) is almost possible with 5.0. The Federated storage engine creates the equivalent of "linked tables" but it is MySQL-to-MySQL only. There are other restrictions, too. As soon as they work out the kinks for MySQL-to-ODBC, you will be in business. Full details: http://dev.mysql.com/doc/mysql/en/federated-storage-engine.html (2) This was suggested earlier (just last week) and an example was walked through on the list. Really, this is an Oracle question and I would happily refer you to any Oracle docs on how to create such an ODBC-linked table. I don't know where to look so I Googled: http://www.google.com/search?hl=en&q=oracle+heterogenous+link+odbc&btnG=Google+Search (hit #2)This link seems promising. Try substituting references to their drivers with references to the MyODBC driver: http://www.easysoft.com/applications/oracle/hsodbc.html (hit #4)This also looks to be useful. Substitute MS SQL server information with MySQL values where appropriate. http://www.databasejournal.com/features/oracle/article.php/3442661 (hit #5) (OMG!!) This one actually describes linking Oracle to MySQL : http://techrepublic.com.com/5100-9592-5725974.html One of these or some of the other appx 48500 other hits has GOT to work for you.
