Hello,
I have the following SQL query.
Code:
function get_panel()
{
$this->db->select('Object_ID, Object_Desc');
$this->db->order_by('Primary_ID', 'random');
$query = $this->db->get('panelbase');
return $query->result_array();
}Please ignore, I have found a solution. Apologies for a pointless thread.

$this->db->limit(1);
I think I read once that random order by is expensive compared to calculating the max row number, then using a php random function to pick a row #, and doing a lookup of that row.

Okay, well I will google up on it. Thank you very much for the advice.
