I have MySQL installed on an Ubuntu machine.
I added this line in /etc/mysql/my.cnf
group_concat_max_len=15360
But there is no effect. Every time I restart mysql, the value is set to 1,024. I have to manually run
SET GLOBAL group_concat_max_len=15360
...every time I start up mysql.
Why is my.cnf not working the way I thought it should? Thank you
