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

CI3 Example, you cant combine them, but you can execute a seperate query, such as:

public function myModelFunction($id){

//set mysql session variable
$this->db->query("SET @@group_concat_max_len = 2048;");

//actual query
$query= $this->db->query("").....
