对象排序顺序错误

Question

我试图找出 xPDO SQL 查询的排序顺序有什么问题，

这个查询

$criteria = $this->modx->newQuery($table);
$criteria->sortby($sortby,$sortdir);
$options = $this->modx->getCollectionGraph($table,$criteria);
$criteria->prepare();
echo '<pre>'.$criteria->toSQL().'</pre>';

导致这条 SQL ~ 这是正确的：

SELECT `Location`.`id` AS `Location_id`, `Location`.`created` AS `Location_created`,
 `Location`.`modified` AS `Location_modified`, `Location`.`location` AS 
`Location_location`, `Location`.`group` AS `Location_group`, `Location`.`comment` 
AS `Location_comment` 
FROM `flow_location` AS `Location` ORDER BY location asc

但是，如果我尝试循环查询：

foreach($options as $option) {
    echo $option->get($value).'<br>';
}

它将在数据库中按订单ID显示记录！？

我该如何解决这个问题？

Answer 1

您按location asc 订购，但您的查询中未定义location。您将列 location 重命名为 Location_location，因此您应该通过 Location_location asc 订购。

SELECT `Location`.`id` AS `Location_id`, `Location`.`created` AS `Location_created`,
 `Location`.`modified` AS `Location_modified`, `Location`.`location` AS 
`Location_location`, `Location`.`group` AS `Location_group`, `Location`.`comment` 
AS `Location_comment` 
FROM `flow_location` AS `Location` ORDER BY location asc
