MySQL group_concat_max_len in a query

Question

I\'m searching a way to insert this

SET GLOBAL group_concat_max_len=15000

in an existing SQL query such as the following:

SELECT *         


        

Answer 1

For new user, while searching for solution on increasing group_concat_max_len i identified that in certain cases variable was not defined in my.cnf file. Nothing to worry about just addup this variable group_concat_max_len=XXXXX under heading [mysqld] in my.cnf file and restart mysql... you are DONE !!!

XXXXX = you desired value eg: 2048,4096 etc.
