OpenAccess has its own logging mechanism, you just have to enable it. Open the OpenAccess menu -> "Configuration" -> "Backend Configuration Settings", scroll to the "Logging" section and enable "Event tracing". You can choose logging to a file, to the Output console of Visual Studio or both. If file logging is enabled, you have to specify a file name as well. The log level should be "normal" or higher to track the SQL statements.
