While migrating a client website from one WHM/cPanel to another WHM/cPanel, I got an SQL error “Incompatible with sql_mode=only_full_group_by“. Below is the complete error message.
SELECT list is not in GROUP BY clause and contains nonaggregated column 'dbname.p.picfile' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by
Solution: MySQL 5.7.5+ has changed
GROUP BY behavior to be SQL99 compliant (Older versions were not) and that was the reason for the error.
The workaround is to edit your MySQL configurations to remove
ONLY_FULL_GROUP_BY option from
sql_mode. This will change
GROUP BY behavior back to its pre-MySQL 5.7.5 behavior.
If you have access to MySQL configuration file
my.cnf, open the file:
# vim /etc/mysql/my.cnf
and add the below line 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"
Restart the MySQL service:
# systemctrl restart mysql
ONLY_FULL_GROUP_BY in WHM/cPanel
If your domain is on a cPanel (Shared Hosting), then you need to contact your hosting provider to update the same.
If you have access to WHM, then access
SQL Services from WHM as shown below:
Variables from the menu and search for
Click on edit button and change remove
ONLY_FULL_GROUP_BY. Once edited, click on
