I am using Amazon RDS for mysql db. I want to run some SET commands for eg:

SET GLOBAL group_concat_max_len =18446744073709551615

But when I run this command I get this error

ERROR 1227 (42000): Access denied; you need (at least one of) the SUPER privilege(s) for this operation

When I try to add privileges, it does not allow me to add. Any help or inputs?

Amazon does not allow you to change or modify MySQL system variables directly. You will have to use RDS parameter groups that allow you to modify some selected MySQL system variables.

So, to configure group_concat_max_len, use an RDS parameter group.
