PDOException: SQLSTATE[42S22] When adding quiz content
The error was somehow related to the UUID module, which couldn't be disabled without derailing the entire website. Here's how I fixed it.


uninstalled the feature that held the affected quiz module

drush pm-disable &lt;my_feature&gt;
drush pm-uninstall &lt;my_feature&gt;
uninstalled the quiz module and all the modules dependent on it:

drush pm-disable quiz
drush pm-uninstall quiz
moved the quiz module files to my temp backup outside the drupal root: 


mv sites/all/modules/contrib/quiz ../&lt;temp_backups&gt;/quiz


downloaded the quiz module fresh and reenabled it and all the dependent modules and reenabled the feature that contained it:


drush dl quiz

drush en quiz

That took care of this particular error.

Please note: I did not yet have any quiz data or content set up; this guideline is only safe for a dev environment. I have not tested it with any actual content or user data.
