Disable ONLY_FULL_GROUP_BY

Question

I accidentally enabled ONLY_FULL_GROUP_BY mode like this:

SET sql_mode = 'ONLY_FULL_GROUP_BY';

How do I disable it?

Why would you want to disable a mode that makes MySQL better comply with SQL standards, and one, too, that teaches you to be more careful in writing your queries? — Andriy M, May 29 '14 at 08:11
This is a good question with the release of mySQL 5.7 which ships with this mode enabled by default. Checking your setup in mysql as per Taran's answer http://stackoverflow.com/a/31058962/438089 and copying the result before adding these options, removing the ONLY_FULL_GROUP_BY (and I remove the "zero dates" ones too) into the line as per br3nt's answer http://stackoverflow.com/a/33476480/438089 (In ubuntu the path is /etc/mysql/my.cnf) and restarting mysql seems to work well. — billythekid, Dec 10 '15 at 12:24
As of Mysql 5.7 you may, alternatively, use the ANY_VALUE(`column`) function to retrofit your query. See doc [here](https://dev.mysql.com/doc/refman/5.7/en/miscellaneous-functions.html) — Qoheleth-Tech, May 23 '16 at 16:59
@AndriyM I'll need to use this soon because I'm porting a whole load of old applications to a new server and they need to work, whether I have the source or not. — Jaydee, May 27 '16 at 13:40
@Qoheleth-Tech - that's very useful - was searching for something like this function and didn't know it existed. thanks for the tip! — But those new buttons though.., Jun 16 '16 at 16:19
@AndriyM Because if I am grouping by a unique index column, then I ALREADY know that every row will be unique - adding a separate group by command for every. single. column. in the table is a royal pain. — Benubird, Jun 23 '17 at 11:58
@Benubird: Yes, that's the one legitimate use case for this mode, something I obviously didn't realise (or not immediately, anyway) at the time. Touché. — Andriy M, Jun 23 '17 at 12:14
before trying to disable it, I recommend seeing this https://stackoverflow.com/a/38551525/3160597 — azerafati, Jul 08 '17 at 13:02
@ZviBar - please update the right answer according to comments bellow — Mladen Janjetovic, Nov 05 '17 at 14:25
@Benubird Is it a pain though? Can't you just refer to the columns by their ordinal and put "group by 1,2,3,4,5" at the end? Our data architect followed this advice. He set the sql_mode to '' globally across the whole database, then when an all zero date made it's way into a table it took down an application on two separate occasions. — user988346, Nov 17 '20 at 08:45
alternatively, for any specific query - you can also use any_value(). https://dev.mysql.com/doc/refman/5.7/en/group-by-handling.html — Channa, Jun 24 '21 at 05:20
in my case just having SET sql_mode = '' in the ini file was not enough. I needed to populate it with something for MySQL to recognize the change; in my case I just changed it to SET sql_mode = 'ERROR_FOR_DIVISION_BY_ZERO' — Philip, Sep 18 '21 at 10:37
If you are working over some mysql client then set session sql_mode='something or empty'; will help. — Haisum Usman, Jun 10 '22 at 17:20
The only correct answer to this question is: [MySQL Handling of GROUP BY](https://dev.mysql.com/doc/refman/8.0/en/group-by-handling.html). Please read it before upvoting this question (or any of the "lot of" _answers_ ) — Luuk, Jun 26 '22 at 07:51

This works, but when I restart the mysql server, defaults are restored... why? is there a persistent solution? Thanks! – Vincent Pazeller Nov 16 '16 at 09:15

To answer to my question (persistent solution): you have to put the description of sql_mode inside a my.cnf file (/etc/my.cnf for instance) and restart the server. For instance, insert (below the [mysqld] section) sql_mode = "STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION" – Vincent Pazeller Nov 22 '16 at 10:44

What about just setting the session.sql_mode only? That's more portable in many cases as you can put that in your script(s). – TheRealChx101 Apr 16 '17 at 22:20

Please note that @VincentPazeller's comments here are still valid - but in my version 5.7.18, I needed to use `sql-mode=` instead of `sql_mode=` (note the dash instead of an underscore) – Warren Sergent Apr 27 '17 at 23:42

There should be a warning that this will copy the `SESSION sql_mode` value to the `GLOBAL sql_mode` value, affecting only all future connections and that the global/session values are not inherited from each other during the current session. As there seems to be some confusion as to how session and global work. In this instance the OP would have a resulting `GLOBAL sql_mode=""` and `SESSION sql_mode="ONLY_FULL_GROUP_BY"` which may not be desired. – Will B. Dec 31 '19 at 21:16
This acts as a temporary solution for me. After a certain period of time, I have to run the query again and re-run the spring boot jar for it to work – Naanavanalla Aug 02 '20 at 14:37
Remember to reconnect to the database. – Miquéias Francisco Jan 08 '21 at 00:29

for MAMP PRO, under File > Open Template. I found a my.cnf template in there. There was a sql_mode variable set in there. Changing that there makes it a permanent change. – Pierre-Verthume Larivière Jul 06 '21 at 16:14
I'm in Linux and the instructions for removing ONLY_FULL_GROUP_BY worked in the terminal, but did not exactly solve my problem. I am using Cold Fusion, and apparently Cold Fusion restarts MySql every time you start a query -- so MySql goes back to its default. I was able to solve the problem by putting the line in my query. – Betty Mock Oct 26 '22 at 21:38
I am baffled about why this option is defaulting. It makes no sense to me. If I group-by I mean to do a roll-up, and I certainly don't want to roll-up on the unaggregated fields -- I want the sums at each sort break. Can anyone explain why this mode has been created? – Betty Mock Oct 26 '22 at 21:41

Update:

To keep your current mysql settings and disable ONLY_FULL_GROUP_BY I suggest to visit your phpmyadmin or whatever client you are using and type:

SELECT REPLACE(@@sql_mode,'ONLY_FULL_GROUP_BY','') copy_me

next copy result to your my.ini file.

mint: sudo nano /etc/mysql/my.cnf

ubuntu 16 and up: sudo nano /etc/mysql/my.cnf

ubuntu 14-16: /etc/mysql/mysql.conf.d/mysqld.cnf

Caution! `copy_me` result can contain a long text which might be trimmed by default. Make sure you copy whole text!

old answer:

If you want to disable permanently error "Expression #N of SELECT list is not in GROUP BY clause and contains nonaggregated column 'db.table.COL' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by" do those steps:

sudo nano /etc/mysql/my.cnf

Add this to the end of the file

[mysqld]  
sql_mode = "STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"

sudo service mysql restart to restart MySQL

This will disable ONLY_FULL_GROUP_BY for ALL users

This worked for Ubuntu 16.04 (14 to 16 upgrade woes..). The /etc/mysql/my.cnf is the correct file. The file mentioned by knb is included within this my.cnf file, in 16.04 at least (configuration is now split up into multiple files). – jwinn Dec 30 '16 at 04:52
Don't blindly replace the value with an arbitrary one ! Check the current value, and just remove what you don't want. In other words, use the value from the best non-selected answer : Execute `SELECT REPLACE(@@sql_mode,'ONLY_FULL_GROUP_BY',''));` to avoid making a mistake. Anyway, glad you gave the config file's location. – Balmipour Feb 28 '17 at 23:19
It's funny - I could spend years in college learning about software and database in particular. Therefore, I expect GROUP BY to work with some degree of certainty based on my training and course instruction plus resources like MDN and w3schools. Then, all of a sudden I encounter MySQL in production and learn about some non-compliance issue centered around this topic.

the actual place where you'll see `[mysqld]` might not be in this file, it might be in an include directory. Use this command first: `grep -R "\[mysqld\]" *` to see what's there - and for that matter try `grep -R "\bsql_mode\b" *` – Oliver Williams Jan 23 '18 at 20:12
Indeed, the actual file I needed to edit was located at /etc/mysql/mysql.conf.d/mysqld.cnf (Ubuntu 16.04) – Matt Kieran Feb 25 '18 at 14:15
Be careful also that the result from the SELECT REPLACE Query ends up with a leading comma. This may not hurt anything but I would not want to take a chance – Burndog Jun 07 '18 at 17:50
On Ubuntu 18.04.2 I cannot make this pernanent. I edited the file `/etc/mysql/conf.d/mysql.cnf` but the setting is still there, If I check with `SELECT @@sql_mode`. I also rebooted the mashine - still there – rubo77 Mar 22 '19 at 07:15

Be careful using

SET sql_mode = ''

This actually clears all the modes currently enabled. If you don't want to mess with other settings, you'll want to do a

SELECT @@sql_mode

first, to get a comma-separated list of the modes enabled, then SET it to this list without the ONLY_FULL_GROUP_BY option.

@KevinMeredith my reading of the [docs](http://dev.mysql.com/doc/refman/5.7/en/sql-mode.html) is there's no way to turn one mode on/off at a time – all the examples require you to supply a comma-separated list of the ones you want - e.g. `SET sql_mode = 'STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION';` – William Turrell Dec 26 '15 at 00:26

If this is a permanent change, edit my.cnf with a line like this: `sql_mode=`, then stop and start your server. Follow the docs for your operating system for the location of, and best way to edit, my.cnf. – blackwood Jul 11 '16 at 14:06

Adding only one mode to sql_mode without removing existing ones:

SET sql_mode=(SELECT CONCAT(@@sql_mode,',<mode_to_add>'));

Removing only a specific mode from sql_mode without removing others:

SET sql_mode=(SELECT REPLACE(@@sql_mode,'<mode_to_remove>',''));

In your case, if you want to remove only ONLY_FULL_GROUP_BY mode, then use below command:

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

I have noticed that @Eyo Okon Eyo solution works as long as MySQL server is not restarted, then defaults settings are restored. Here is a permanent solution that worked for me:

To remove particular SQL mode (in this case ONLY_FULL_GROUP_BY), find the current SQL mode:

SELECT @@GLOBAL.sql_mode;

copy the result and remove from it what you don't need (ONLY_FULL_GROUP_BY)

e.g.:

ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION

to

STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION

create and open this file:

/etc/mysql/conf.d/disable_strict_mode.cnf

and write and past into it your new SQL mode:

[mysqld]
sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION

restart MySQL:

sudo service mysql restart

Or you can use ANY_VALUE() to suppress ONLY_FULL_GROUP_BY value rejection, you can read more about it here

Add or Remove modes to `sql_mode`

MySQL 5.7.9 or later

To add or remove a mode from sql_mode, you can use list_add and list_drop functions.

To remove a mode from the current SESSION.sql_mode, you can use one of the following:

SET SESSION sql_mode = sys.list_drop(@@SESSION.sql_mode, 'ONLY_FULL_GROUP_BY');
SET sql_mode = sys.list_drop(@@sql_mode, 'ONLY_FULL_GROUP_BY');
SET @@sql_mode = sys.list_drop(@@sql_mode, 'ONLY_FULL_GROUP_BY');

To remove a mode from the GLOBAL.sql_mode that persists for the current runtime operation, until the service is restarted.

SET GLOBAL sql_mode = sys.list_drop(@@GLOBAL.sql_mode, 'ONLY_FULL_GROUP_BY');

MySQL 5.7.8 or prior

Since the sql_mode value is a CSV string of modes, you would need to ensure that the string does not contain residual commas, which can be accomplished by using TRIM(BOTH ',' FROM ...).

To remove a mode from the sql_mode variable, you would want to use REPLACE() along with TRIM() to ensure any residual commas are removed.

SET SESSION sql_mode = TRIM(BOTH ',' FROM REPLACE(@@SESSION.sql_mode, 'ONLY_FULL_GROUP_BY', ''));
SET GLOBAL sql_mode = TRIM(BOTH ',' FROM REPLACE(@@GLOBAL.sql_mode, 'ONLY_FULL_GROUP_BY', ''));

To add a mode to the sql_mode variable, you would want to use CONCAT_WS(',', ...), to ensure a comma is appended with the current modes and TRIM() to ensure any residual commas are removed.

SET SESSION sql_mode = TRIM(BOTH ',' FROM CONCAT_WS(',', 'ONLY_FULL_GROUP_BY', @@SESSION.sql_mode));
SET GLOBAL sql_mode = TRIM(BOTH ',' FROM CONCAT_WS(',', 'ONLY_FULL_GROUP_BY', @@GLOBAL.sql_mode));

NOTE: Changing the GLOBAL variable does not propagate to the SESSION variable, until a new connection is established.

The GLOBAL variable will persist until the running service is restarted.

The SESSION variable will persist for the current connection, until the connection is closed and a new connection is established.

Revert to `GLOBAL.sql_mode`

Since SET sql_mode = 'ONLY_FULL_GROUP_BY'; was executed without the GLOBAL modifier, the change only affected the current SESSION state value, which also pertains to @@sql_mode. To remove it and revert to the global default on server restart value, you would want to use the value from @@GLOBAL.sql_mode. [sic]

The current SESSION value is only valid for the current connection. Reconnecting to the server will revert the value back to the GLOBAL value.

To revert the current session state value to the current global value, you can use one of the following:

SET SESSION sql_mode = @@GLOBAL.sql_mode;
SET @@sql_mode = @@GLOBAL.sql_mode;
SET sql_mode = @@GLOBAL.sql_mode;

Change SESSION.sql_mode value to ONLY_FULL_GROUP_BY

SET sql_mode = 'ONLY_FULL_GROUP_BY';
SELECT @@sql_mode, @@GLOBAL.sql_mode;
+--------------------+----------------------------------------------+
| @@sql_mode         | @@GLOBAL.sql_mode                            |
+--------------------+----------------------------------------------+
| ONLY_FULL_GROUP_BY | NO_AUTO_VALUE_ON_ZERO,NO_ENGINE_SUBSTITUTION |
+--------------------+----------------------------------------------+

Revert the SESSION.sql_mode value to the GLOBAL.sql_mode value

SET sql_mode = @@GLOBAL.sql_mode;
SELECT @@sql_mode, @@GLOBAL.sql_mode;
+----------------------------------------------+----------------------------------------------+
| @@sql_mode                                   | @@GLOBAL.sql_mode                            |

+----------------------------------------------+----------------------------------------------+

Server Restart Persistent `sql_mode` using the option file

To set the SQL mode at server startup, use the --sql-mode="modes" option on the command line, or sql-mode="modes" in an option file such as my.cnf (Unix operating systems) or my.ini (Windows). [sic]

Please see your version of MySQL to determine the supported and default modes.

MySQL >= 5.7.5, <= 5.7.6 default

[mysqld]
    
sql-mode="ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,NO_ENGINE_SUBSTITUTION"

Please see the Option File Syntax for more information.

The syntax for specifying options in an option file is similar to command-line syntax. However, in an option file, you omit the leading two dashes from the option name and you specify only one option per line. For example, --quick and --host=localhost on the command line should be specified as quick and host=localhost on separate lines in an option file. To specify an option of the form --loose-opt_name in an option file, write it as loose-opt_name.

The value optionally can be enclosed within single quotation marks or double quotation marks, which is useful if the value contains a # comment character.

Default `sql_mode` values

Since the MySQL documentation per-version values have been removed, I have added them here for your reference.

MySQL 8.0 [sic]
MySQL 5.7 [sic]
MySQL 5.6 [sic]

MySQL >= 8.0.11 8.0.5 - 8.0.10 Skipped

ONLY_FULL_GROUP_BY STRICT_TRANS_TABLES NO_ZERO_IN_DATE NO_ZERO_DATE ERROR_FOR_DIVISION_BY_ZERO NO_ENGINE_SUBSTITUTION

MySQL >= 5.7.8, <= 8.0.4

ONLY_FULL_GROUP_BY STRICT_TRANS_TABLES NO_ZERO_IN_DATE NO_ZERO_DATE ERROR_FOR_DIVISION_BY_ZERO NO_AUTO_CREATE_USER NO_ENGINE_SUBSTITUTION

MySQL 5.7.7

ONLY_FULL_GROUP_BY STRICT_TRANS_TABLES NO_AUTO_CREATE_USER NO_ENGINE_SUBSTITUTION

ONLY_FULL_GROUP_BY STRICT_TRANS_TABLES NO_ENGINE_SUBSTITUTION

MySQL >= 5.6.6, <= 5.7.4

NO_ENGINE_SUBSTITUTION

MySQL <= 5.6.5

''

At least for MySQL 8, setting in my.cnf requires two changes: the variable name has an underscore and the settings list is comma separated. Eg: [mysqld] sql_mode="STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION" — Mark Rogers, Jul 05 '20 at 07:58
As mentioned in the answer, the listed sql_mode values were copied as displayed on the MySQL website, which can be seen by clicking the `[sic]` links. When setting sql_mode within the [option file (my.cnf)](https://dev.mysql.com/doc/refman/8.0/en/sql-mode.html#sql-mode-setting) the manual states that you should remove the leading two dashes of the command-line variable `--sql-mode=` in favor of using `sql-mode=`, https://dev.mysql.com/doc/refman/8.0/en/option-files.html#option-file-syntax however either syntax works currently. Lastly quotes are not required to wrap the sql_mode values. — Will B., Jul 05 '20 at 15:09

The MySQL documentation also specifies the following methods:

Set sql-mode="<modes>" in an option file such as my.cnf (Unix operating systems) or my.ini (Windows).
To set the SQL mode at server startup via the command line, use the --sql-mode="<modes>" option.

*Where <modes> is a list of different modes separated by commas.

To clear the SQL mode explicitly, set it to an empty string using --sql-mode="" on the command line, or sql-mode="" in an option file.

I added the sql-mode="" option to /etc/my.cnf and it worked.

This SO solution discusses ways to find out which my.cnf file is being used by MySQL.

Don't forget to restart MySQL after making changes.

As of MySQL 5.7.x, the default sql mode includes ONLY_FULL_GROUP_BY.

(Before 5.7.5, MySQL does not detect functional dependency and ONLY_FULL_GROUP_BY is not enabled by default).

ONLY_FULL_GROUP_BY: Non-deterministic grouping queries will be rejected

For more details check the documentation of sql_mode

You can follow either of the below methods to modify the sql_mode

Method 1:

Check default value of sql_mode:

SELECT @@sql_mode

Remove ONLY_FULL_GROUP_BY from console by executing below query:

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

Method 2:

Access phpmyadmin for editing your sql_mode

Login on phpmyadmin and open localhost
Top on Variables present on the top in menu items and search out for sql mode
Click on edit button to remove ONLY_FULL_GROUP_BY and save

Restart MySQL server

 sudo service mysql restart

OR

Logout phpmyadmin and login again.

On MySQL 5.7 and Ubuntu 16.04, edit the file mysql.cnf.

$ sudo nano /etc/mysql/conf.d/mysql.cnf

Include the sql_mode like the following and save the file.

[mysql]
sql_mode=IGNORE_SPACE,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION

Observe that, in my case, I removed the mode STRICT_TRANS_TABLES and the ONLY_FULL_GROUP_BY.

Doing this, it will save the mode configuration permanently. Differently if you just update the @@sql_mode through MySQL, because it will reset on machine/service restart.

After that, to the modified configuration take in action, restart the mysql service:

$ sudo service mysql restart

Try to access the mysql:

$ mysql -u user_name -p

If you are able to login and access MySQL console, it is ok. Great!

BUT, if like me, you face the error "unknown variable sql_mode", which indicates that sql_mode is an option for mysqld, you will have to go back, edit the file mysql.cnf again and change the [mysql] to [mysqld]. Restart the MySQL service and do a last test trying to login on MySQL console. Here it is!

I would strongly recommend the aforementioned approach than setting it on the session, thanks to @alexandre-ribeiro. For those who have Ubuntu 16.04 and mysql 5.7.x, better edit the file and enter the _ini_ directive *sql_mode=* under *[mysqld]* group, as declaring against *[mysql]* does not work, as per my experience. — codarrior, Sep 18 '17 at 04:07
I have MySQL 5.7.22. It's strange, but I had to remove **both** STRICT_TRANS_TABLES and ONLY_FULL_GROUP_BY from the sql_mode declaration in my.cnf, as shown above, for this to work. In reality, I only want to remove the ONLY_FULL_GROUP_BY mode. If I do "set global/session sql_mode = ..." I can remove just ONLY_FULL_GROUP_BY without having to remove STRICT_TRANS_TABLES for it to work. But since this doesn't survive restarts, so it's not much use to me. — RayCh, Jun 11 '18 at 10:28

Connect to you server via SFTP - SSH (root) and download the file /etc/my.cnf
Open with a text editor my.cnf file on your local PC and paste into it (under [mysqld] section) the entire line you copied at step (2) but remove ONLY_FULL_GROUP_BY,

The best is to try to use ONLY_FULL_GROUP_BY on new projects while remaining backward compatible on existing sites and databases. For this I opted for a modification of the SQL Mode when loading mysqli, respectively PDO in my classes.

For mysqli :

mysqli_query($this->link,"SET SESSION sql_mode=(SELECT REPLACE(@@sql_mode,'ONLY_FULL_GROUP_BY',''))");

For PDO class :

PDO::MYSQL_ATTR_INIT_COMMAND => "SET SESSION sql_mode=(SELECT REPLACE(@@sql_mode,'ONLY_FULL_GROUP_BY',''))"

Example with PDO init :

try {
    $dns     = 'mysql:host=localhost;dbname=' . $prod_db;
    $user    = _DBUSER_;
    $pass    = _DBPASS_;
    $options = array(
        PDO::MYSQL_ATTR_INIT_COMMAND => "SET NAMES utf8",
        PDO::MYSQL_ATTR_INIT_COMMAND => "SET SESSION sql_mode=(SELECT REPLACE(@@sql_mode,'ONLY_FULL_GROUP_BY',''))"
    );

    $db = new PDO($dns, $user, $pass, $options);
} 

catch(Exception $e) {
    mail("contact@xxxxxx.xx","Database Error ",$dns.",".$user);
    echo "Unable ot connect to mySQL : ", $e->getMessage();
    die();
}

Thus, the new classes created on the same server will work with new standard of databases.

One important thing to note, if you have ANSI on sql_mode:

Equivalent to REAL_AS_FLOAT, PIPES_AS_CONCAT, ANSI_QUOTES, IGNORE_SPACE, and (as of MySQL 5.7.5) ONLY_FULL_GROUP_BY.

See https://dev.mysql.com/doc/refman/5.7/en/sql-mode.html#sqlmode_ansi

in case anyone using Drupal 8 face this issue with mysql 8, I fixed that by overriding the default configuration by adding this piece of code.

Source: https://www.drupal.org/project/drupal/issues/2856270

The option, just in case:

'init_commands' => array(
    'sql_mode' => "SET sql_mode =''"
  )

Leaving the sql_mode blank won't have any side effects? – Ahmad Karimi Dec 30 '20 at 07:33
@AhmadKarimi Maybe, so for those who are worried about this, here is another option they can set. 'sql_mode' => "SET sql_mode = 'STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION |'" – Naser Nikzad Jan 14 '21 at 07:06
Remember to clear cache after this config change as well, drush cr – Naser Nikzad Aug 18 '21 at 05:42
In the early days MySQL had problems to detect functional dependencies with `GROUP BY`, so they just allowed any column in the `SELECT` clause regardless of what was in `GROUP BY`. Then they started fixing this and invented ONLY_FULL_GROUP_BY mode. And when they finally got it right, they made ONLY_FULL_GROUP_BY the default mode. So, do the problems with Drupal indicate that there are still edge cases where MySQL's functional dependencies detection fails or is Drupal buggy? – Thorsten Kettner Aug 19 '21 at 12:18

In case someone else facing same issue as me. On Ubuntu 16.04, the only persistent solution it worked for me:

Edit /lib/systemd/system/mysql.service and set it to:

[Unit]
Description=MySQL Community Server
After=network.target

[Install]
WantedBy=multi-user.target

[Service]
User=mysql
Group=mysql
PermissionsStartOnly=true
ExecStartPre=/usr/share/mysql/mysql-systemd-start pre
# Normally, we'd simply use:
# ExecStart=/usr/sbin/mysqld
ExecStart=/usr/sbin/mysqld --sql-mode=ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION
ExecStartPost=/usr/share/mysql/mysql-systemd-start post
TimeoutSec=600
Restart=on-failure
RuntimeDirectory=mysqld
RuntimeDirectoryMode=755`

To permanently disable it in windows, navigate to C:\ProgramData\MySQL\MySQL Server (version no)/. Open my.ini file then find a line starting with sql-mode= delete the text "ONLY_FULL_GROUP_BY" then restart the MySQL service.

I found this line by default in my.ini

 sql-mode="ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION"

And removed ONLY_FULL_GROUP_BY,

DONT FORGET TO RESTART MYSQL: net stop [YOUR MYSQL NAME];net start [YOUR MYSQL NAME]

Disable ONLY_FULL_GROUP_BY
