execute mysql stored procedures with CodeIgniter

[eluser]haekal[/eluser]

Code:

$sql = 'call prc_groupmenu(?)';
$param = array($idgroupuser);
$query = $this->db->query($sql,$param);

An Error Was Encountered
Error Number: 1312

PROCEDURE optis.prc_groupmenu can't return a result set in the given context

call prc_groupmenu('1')

I've try that... still error for me... any other solution???
maybe you've been modified another file ??
I see that you've have wrote $this->my_db->query, not like usual $this->db->query
did you change database driver class ???

thanks...
