How to resolve “ORDER BY clause is not in SELECT list” caused MySQL 5.7 with SELECT DISTINCT and ORDER BY

Question

I installed the new Ubuntu and my code has got a problem with MySQL.

( ! ) Warning: PDOStatement::execute(): SQLSTAT         


        

Answer 1

If you have control of the server and you are running legacy code you can't easily change, you can adjust the SQL mode of the server and remove "only_full_group_by" either for the duration of boot, by running the query

SET GLOBAL sql_mode=(SELECT REPLACE(@@sql_mode,'ONLY_FULL_GROUP_BY',''));

or by adding sql_mode='' to your my.cnf file.

Obviously its better to change your code if you have the possibility, but if not, this will disable that warning.

Try this:

    SELECT p.products_id,  p.products_price  
      FROM :table_products p
 LEFT JOIN :table_specials s on p.products_id = s.products_id 
     WHERE
           products_status = :products_status AND
           products_view = :products_view AND
           p.products_archive = :products_archive
  ORDER BY rand(),  p.products_date_added DESC
  GROUP BY p.products_id,p.products_price 
     LIMIT :products_limit
