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(): SQLSTATE[HY000]: General error: 3065 
Expression #2 of ORDER BY clause is not in SELECT list, references column 'clicshopping_test_ui.p.products_date_added' which is not in SELECT list; this is incompatible with DISTINCT 
in /home/www//boutique/includes/OM/DbStatement.php on line 97s

It seems MySQL 5.7 does'nt allow a request like:

select .... distinct with  order by rand(), p.products_date_added DESC

If I use this it works:

select distinct .... with  order by rand(), 

How to resolve this situation ?

My SQL request in PHP

 $Qproduct = $OSCOM_PDO->prepare('select distinct 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
            limit :products_limit');
                  $Qproduct->bindInt(':products_status', 1);
                  $Qproduct->bindInt(':products_view', 1);
                  $Qproduct->bindInt(':products_archive', 0);
                  $Qproduct->bindInt(':products_limit', 
                  (int)MODULE_FRONT_PAGE_NEW_PRODUCTS_MAX_DISPLAY);

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.

Answer 2

In order to fix the issue open the following file:

/etc/mysql/mysql.conf.d/mysqld.cnf

and add the following line under [mysqld] block

sql-mode=""

Answer 3

If you have phpMyAdmin:

1-go to the Variables tabs

2-search label "sql mode"

3-edit the content and delete the mode : "ONLY_FULL_GROUP_BY"

4-save

NB: don't forget to verify the comma separator

Answer 4

1. You can run as said :

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

But if you restart your serveur, you may have to re run it.

2. You can update the mysql server configuration:

• on Windows, the ${MY_SQL_HOME}/my.cnf (or my.ini )
• on Linux, one of the following: etc/my.cnf , /etc/mysql/my.cnf , /usr/etc/my.cnf or ~/.my.cnf

[mysqld]

# RESOLVE order-by-clause-is-not-in-select-list by removing ONLY_FULL_GROUP_BY from the sql-mode list
sql-mode="STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION"

Answer 5

With MAMP PRO

You cannot edit your my.cnf file directly. You must use the MAMP PRO interface to edit your my.cnf file. In the menu go to File > Edit Template > MySQL > my.cnf. Then add sql_mode='' under the [mysqld] key

Answer 6

This worked for me that @pvgoran suggested

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

You can run this when you want.

Answer 7

To get ->distinct('some_column') to work for me, I needed to disable ONLY_FULL_GROUP_BY option in mysql modes.

Rather than edit the mysql config file on the filesystem, I followed the instructions at Laravel : Syntax error or access violation: 1055 Error and added this to config/database.php :

        'strict' => true,
        'modes' => [
            // 'ONLY_FULL_GROUP_BY', // disabled to allow grouping by one column
            'STRICT_TRANS_TABLES',
            'NO_ZERO_IN_DATE',
            'NO_ZERO_DATE',
            'ERROR_FOR_DIVISION_BY_ZERO',
            'NO_AUTO_CREATE_USER',
            'NO_ENGINE_SUBSTITUTION'
        ],

In my project, the modes property was non-existent, so I simply pasted that bad boy in there.

NOTE : Make sure you understand that wiping the modes entirely is undesirable, and basically not strict mode, so you will lose debugging warning/error messages about stuff like varchar length exceeded. The trick is to avoid sql_mode="" . Notice how above I am using 6 modes and explicitly omitting ONLY_FULL_GROUP_BY .

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

Answer 9

The answer of rapaelec worked for me (thank's because I couldn't find the mysql.conf file !). But don't forget to go to the homepage of phpmyadmin to see the variables tab.
