Jira issue originally created by user digitalmechanic:

When attempting to reverse engineer an existing Oracle 11g database an exception is thrown (by DBAL) complaining that the type blob is unknown. I believe this is coming from AbstractPlatform.php. I attempted to solve the problem by add a type mapping for blob in PDOOracle\Driver.php (blob => text) and it now complains that "long raw" is unknown.

Unknown database type long raw requested, Doctrine\DBAL\Platforms\OraclePlatform may not support it.
