I'm really confused! I've been trying non stop to connect to an Oracle database through ExpressionEngine throughout the last two weeks. I've finally given up when I saw a previous post(Is it possible to use ExpressionEngine with an Oracle database?) that stated that EE will not work with Oracle.

the error I'm getting is 'driver not found' when I use the PDO oci or undeclared function connect_oci().

If this is true, why doesn't Oracle connect to EE? Why can Filemaker connect to EE? If this is true, is there a way to create documents that will allow Expression Engine to use Oracle? Can EE only use MySQL and Mysqli?

CodeIgniter does have a DB driver for oci8. Have you changed your driver? I mean, so much of the core is built around MySQL or equivalents.

You would have to do an entire rewrite of the Database class, as well as catch all manual MySQL commands and make sure they are Oracle-syntax correct. You would also have to do the same for all of your add-ons. This is really a futile (or epic) endeavor.

You are in such a better position create your own module and import an Oracle driver, and build your own Oracle ORM as a module. Or, even simplier, why the heck aren't you just doing a database migration from Oracle to MySQL or MariaDB???

Edit

Here is really the best resource for building your own modules/addons:

I can help you further, but only if you're building your own module. I'm a professional developer so you'll have to contract me if you want me to do it for you :) But if you can get it going, you can post new questions to the forum and we can help you.

  • Do you know where I can find tutorials or examples on building modules on EE and doing some of the things your recommending?

  • Also, to answer your question, I would be considered a guest to the database I would like to connect to.
