RE: [PHP] Re: [PHP-DB] MySQL -> Oracle Migration

There is also a class abstraction called Metabase available at phpclasses.upperdesign.com . This class (Metabase) allows you to switch between database with minimal changes. As far as I know, all you have to change is your login and db location info. Hope this helps.

While this would shurely not solve the problems you've mentioned, you can develop your data model and your application much better so they can make use of features like referential integrety or subselects that are not available with MySQL or avoid MySQL features like the LIMIT in SELECTs that can give you a hard time porting to Oracle. -Andreas -- Andreas Karajannis GMD National Research Center for Information Technology Schloss Birlinghoven, D-53754 Sankt Augustin Phone +49 2241 142948 -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: php-general-unsubscribe@lists.php.net For additional commands, e-mail: php-general-help@lists.php.net To contact the list administrators, e-mail: php-list-admin@lists.php.net
