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?

Answer 1

To whom is running a VPS/Server with cPanel/WHM, you can do the following to permanently disable ONLY_FULL_GROUP_BY

You need root access (either on a VPS or a dedicated server)

1. Enter WHM as root and run phpMyAdmin

2. Click on Variables, look for sql_mode, click on 'Edit' and copy the entire line inside that textbox

e.g. copy this:

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

3. Connect to you server via SFTP - SSH (root) and download the file /etc/my.cnf

4. 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,

e.g. paste this:

# disabling ONLY_FULL_GROUP_BY
sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION

5. Save the my.cnf file and upload it back into /etc/

6. Enter WHM and go to "WHM > Restart Services > SQL Server (MySQL)" and restart the service
