#1055 - Expression of SELECT list is not in GROUP BY clause and contains nonaggregated column this is incompatible with sql_mode=only_full_group_by

Question

my Query :

select libelle,credit_initial,disponible_v,sum(montant) as montant 
FROM fiche,annee,type where type.id_type=annee.id_type and annee.id_annee=fiche.id_annee 
and annee = year(current_timestamp) GROUP BY libelle order by libelle asc

• Mysql 5.7.9 runs the query without any problem but mysql 5.7.12 display the error above Could you please help me with that

Answer 1

I had a struggle getting this to work i've tested it and it's working on lamp server mysql version 5.12

So, steps to success:

1. sudo vim /etc/mysql/conf.d/mysql.cnf

2. Scroll to the bottom of file Copy and paste

   [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

to the bottom of the file

3. save and exit input mode
4. sudo service mysql restart to restart MySQL.

Done!

Answer 2

This worked for me:

mysql -u root -p
mysql > SET GLOBAL sql_mode=(SELECT REPLACE(@@sql_mode,'ONLY_FULL_GROUP_BY',''));

You might need sudo for the first step:

sudo mysql -u root -p

Answer 3

You need to specify all of the columns that you're not using for an aggregation function in your GROUP BY clause like this:

select libelle,credit_initial,disponible_v,sum(montant) as montant 
FROM fiche,annee,type where type.id_type=annee.id_type and annee.id_annee=fiche.id_annee 
and annee = year(current_timestamp) GROUP BY libelle,credit_initial,disponible_v order by libelle asc

The full_group_by mode basically makes you write more idiomatic SQL. You can turn off this setting if you'd like. There are different ways to do this that are outlined in the MySQL Documentation. Here's MySQL's definition of what I said above:

MySQL 5.7.5 and up implements detection of functional dependence. If the ONLY_FULL_GROUP_BY SQL mode is enabled (which it is by default), MySQL rejects queries for which the select list, HAVING condition, or ORDER BY list refer to nonaggregated columns that are neither named in the GROUP BY clause nor are functionally dependent on them. (Before 5.7.5, MySQL does not detect functional dependency and ONLY_FULL_GROUP_BY is not enabled by default. For a description of pre-5.7.5 behavior, see the MySQL 5.6 Reference Manual.)

You're getting the error because you're on a version < 5.7.5

Answer 4

You can disable sql_mode=only_full_group_by by some command you can try this by terminal or MySql IDE

mysql> set global sql_mode='STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION';

mysql> set session sql_mode='STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION';

I have tried this and worked for me. Thanks :)

Answer 5

Solution 1: Remove ONLY_FULL_GROUP_BY from mysql console

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

you can read more here

Solution 2: Remove ONLY_FULL_GROUP_BY from phpmyadmin

Open phpmyadmin & select localhost
Click on menu Variables & scroll down for sql mode
Click on edit button to change the values & remove ONLY_FULL_GROUP_BY & click on save. 

Answer 6

You have to aggregate by anything NOT IN the group by clause.

So,there are two options...Add Credit_Initial and Disponible_v to the group by

OR

Change them to MAX( Credit_Initial ) as Credit_Initial, MAX( Disponible_v ) as Disponible_v if you know the values are constant anyhow and have no other impact.

Answer 7

Base ond defualt config of 5.7.5 ONLY_FULL_GROUP_BY You should use all the not aggregate column in your group by

select libelle,credit_initial,disponible_v,sum(montant) as montant 
FROM fiche,annee,type 
where type.id_type=annee.id_type 
and annee.id_annee=fiche.id_annee 
and annee = year(current_timestamp) 
GROUP BY libelle,credit_initial,disponible_v order by libelle asc

Answer 8

Same thing is happened with 8.0+ versions as well. By default in 8.0+ version it is "enabled" by default. Here is the link official document reference

In case of 5.6+, 5.7+ versions, the property "ONLY_FULL_GROUP_BY" is disabled by default.

To disabled it, follow the same steps suggested by @Miloud BAKTETE
