To disable ONLY_FULL_GROUP_BY in MySQL, remove ONLY_FULL_GROUP_BY from the sql-mode setting in the MySQL configuration file, /etc/my.cnf. This file can only be modified via SSH as the root user or WHM >> Terminal. ONLY_FULL_GROUP_BY cannot be disabled for a single account or database.
Follow these steps to disable ONLY_FULL_GROUP_BY:
- Log in to your server via SSH as the root user or navigate to WHM >> Terminal.
- Run the following command to determine which sql_mode options are enabled and copy the output:
mysql -sse "SELECT @@GLOBAL.sql_mode;"
Example output (Do not copy the output shown below as it may contain options that are incompatible with your version of MySQL--for example, NO_AUTO_CREATE_USER is not supported by MySQL 8):
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
- Open the
/etc/my.cnffile using any command-line text editor you prefer (ex: vi, vim, nano, etc).vi /etc/my.cnf
vim /etc/my.cnf
nano /etc/my.cnf
- Add sql-mode= to the bottom of the [mysqld] section, followed by the output you copied in step 2, and remove ONLY_FULL_GROUP_BY.
Example (Do not copy the sql-mode line shown below as it may contain options that are incompatible with your version of MySQL--for example, NO_AUTO_CREATE_USER is not supported by MySQL 8):
sql-mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION
- Save and close the file.
- Restart MySQL to load the change by running the following command:
/scripts/restartsrv_mysql
- Run the following command to confirm ONLY_FULL_GROUP_BY was removed from the enabled sql_mode options:
mysql -sse "SELECT @@GLOBAL.sql_mode;"
