SQL Query - El Forum - 09-04-2009

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.
