如何从数据库的一个表中获取显示的数据-Drupal

Question

I am creating a table view for my custom module that displays user some custom data that he created.

Example table hour:

hour_id    hour
  1       07:00
  2       07:30
  3       08:00
  4       08:30

Example table data:

user_id    user   hour_start    hour_end
  1        name     1              3
  2        name     1              2

Note: I save ID from table hour to table data. User has a dropdown menu for start and end.

$result = db_query("SELECT ho.hour,h.hour FROM {data} t
                    INNER JOIN {hour} ho ON t.hour_start=ho.hour_id
                    INNER JOIN {hour} h ON t.hour_end=h.hour_id
                    WHERE t.made=:t",array(":t"=>$temp_user));


    $rows = array();
    foreach($result as $row){
    $rows[] = array ('data' => 
    array(
        $row -> hour, // putting ho.hour gives error
        $row -> hour, // putting h.hour gives error
        ),
    );

My problem is that i get in the table only one hour. How can i get for row one 07:00(1) for one column and 08:00(3) without creating a separate tables for hour_start and hour_end .

Try using column aliases. Change the query to:

SELECT ho.hour ho_hour, h.hour h_hour FROM {data} t ...

and then get the data using:

$row -> ho_hour,
$row -> h_hour,
