Summary13010: MySQL 8 reserved word used as table alias in query

When attempting to view a survey, using MySQL v8, the page fails to load with the error below show to the user:

"CDbCommand failed to execute the SQL statement: SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'groups WHERE questions.gid=groups.gid AND questions.sid=465429 AND questions.l' at line 1."

Steps To Reproduce
  1. Install LimeSurvey using MySQL 5.7 (or another version before 8)
  2. Update MySQL to v8 (in this case, I'm on 8.0.3-rc-log)
  3. Attempt to view a survey in the admin panel (e.g. https://websurvey.local/index.php?r=admin/survey/sa/view/surveyid/465429)
  4. The page fails to load with the above warning
Additional Information

The full query being executed is:

SELECT * FROM lime_questions as questions, lime_groups as groups WHERE questions.gid=groups.gid AND questions.sid=465429 AND questions.language='en' AND questions.parent_qid=0 AND groups.language='en' ORDER BY group_order, question_order

This fails because 'groups' is now reserved starting in MySQL v8.0.2 (

TagsNo tags attached.

@jakebathman: Can you activate debug mode in /application/config/config.php and attach the full error message here?
@olle: Can you add Travis CI testing for MySQL 8 ?

Isn't the latest version of MySQL 5.7?
Travis uses 5.6.
