如何在codeigniter中访问从查询传递的数据

How do I get the data that should be passed back from this query. This is in my model. I don't know if i'm doing this right since I haven't gotten back any output. I have already tested the query in phpmyadmin and it works. I need to be able to pass data from function get_reg2() to my controller successfully.

如何获取应从此查询传回的数据。这是在我的模型中。我不知道我是否正确这样做,因为我没有收到任何输出。我已经在phpmyadmin中测试了查询,它可以工作。我需要能够成功地将函数get_reg2()中的数据传递给我的控制器。

I don't know if the return is doing it right

我不知道回报是否做得对

return $this->db->query($query, $data); 

Joins_model extends CI_Model....
function get_reg2($data){
$query = ('

SELECT DISTINCT
    cm_valuacion.mano_obra,
    cm_nomina.nomina,
    cm_empleado.nombre,
    cm_proveedor.nombre,
    cm_valuacion.hojalateria,
    cm_valuacion.pintura,
    cm_valuacion.mecanica,
    cm_valuacion.refaccion,
    cm_valuacion.tipo,
    cm_valuacion.shojalateria,
    cm_valuacion.spintura,
    cm_valuacion.smecanica,
    cm_valuacion.costoHojalateria,
    cm_valuacion.costoPintura,
    cm_valuacion.costoMecanica,
    cm_valuacion.pv_hojalateria,
    cm_valuacion.pv_pintura,
    cm_valuacion.pv_mecanica,
    cm_valuacion.pc_hojalateria,
    cm_valuacion.pc_pintura,
    cm_valuacion.pc_mecanica,
    cm_compras.precio,
    cm_compras.status
FROM cm_valuacionr,
    cm_nomina
INNER JOIN cm_empleado
    ON cm_nomina.id_empleado = cm_empleado.id
INNER JOIN cm_valuacion
    ON cm_valuacion.id_siniestro = cm_nomina.id_siniestro
INNER JOIN cm_compras
    ON cm_compras.id_siniestro = cm_valuacion.id_siniestro
INNER JOIN cm_proveedor
    ON cm_compras.id_proveedor = cm_proveedor.id
WHERE cm_valuacion.id_siniestro = ?
    AND cm_valuacion.id_complemento = 0
GROUP BY mano_obra
    ');
return $this->db->query($query, $data);

}

}

also I don't know if im receiving it correctly here

我也不知道我是否在这里正确接收它

 $registros = $this->joins_model->get_reg2($id);

what I have in my controller is:

我在控制器中拥有的是:

$registros = $this->joins_model->get_reg2($id);
    $this->load->library('table');
    $this->table->set_empty(" ");
    $this->table->set_heading(
        $this->st_cell('D'),
        $this->st_cell('CANT.'),
        $this->st_cell('PROVEEDOR'),
        $this->st_cell('NOTA'),
        $this->st_cell('DESCRIPCION'),
        $this->st_cell('COSTO'),
        $this->st_cell('VENTA'),
        $this->st_cell('EMPLEADO'),
        $this->st_cell('NOMINA'),
        $this->st_cell('TOTAL')
    );

    foreach ($registros->result() as $registro){
        //this is where I want to be able to specify what parameter I want               
        //to access from the query that was returned. How do I do this?
        //for example theres *nombre* up there and it's there twice. Once
        //for *empleado* and the other for *proveedor*
    }

and using it correctly here;

并在这里正确使用它;

$registros->result() as $registro
