I have migrated my database from older version to newer one.
I have mysql version 5.7.24 now.
I am getting ERROR 1055 (sql_mode=only_full_group_by)
for a query which has group by.
I have set sql_mode='' in both global variable as well as my.cnf file and restarted mysql server.
Still problem persists and getting the same error.
Please help me out resolving this.
