Has anyone managed to get Magento running under MSSQL? Since 1.6 there is the possiblity to change the PDO driver, using some steps:
Rename Mysql.php files to Mssql.php
app/code/core/mage/Core/Model/Resource/Type/Db/Pdo/Mysql.php
lib/Varien/Db/Adapter/Pdo/Mysql.php
lib/Varien/Db/Statement/Pdo/Mysql.php
Modify the files to actually use Mssql
Modify app/etc/local.xml and app/etc/config.xml to use mssql adapter
This basically works, but then you are running into the problem that all (or at least most) install scripts are using MySQL specific syntax. Has anyone undergone the hassle of porting them all to MSSQL?
Any other thoughts in this regard besides waiting for Magento 2.0 to support this natively?! ;)
