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

The MySQL documentation also specifies the following methods:

• Set sql-mode="" 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="" option.

*Where 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.
