error code 1096?

[eluser]CroNiX[/eluser]

Code:

<?php
function getPreguntas()
{    
    $this->db->select('idPregunta');
    $this->db->from('jgo_asignadas_prefree');
    $this->db->where('estado','PD');
    $this->db->where('id',$this->session->userdata('id'));
    $query = $this->db->get();    
    if($query->num_rows() > 0){        
        return $query;
    }
}

I believe where you issue the $this->db->get(); 2x is causing the error. Just return the result.
