Need to increase group_concat_max_len variable because currently it supports 1024 character when using GROUP_CONCAT.
When I run this SET GLOBAL group_concat_max_len = 4096, I’m getting below error.
Error Code: 1227. Access denied; you need (at least one of) the SUPER or SYSTEM_VARIABLES_ADMIN privilege(s) for this operation
While using SET SESSION or SET LOCAL, sometime it’s working but most of the time its not working.
