對象的排序順序是錯誤

Question

我試圖弄清楚什麼是錯上xPDO SQL查詢排序順序，

這個查詢

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

結果在這個SQL〜這是正確的：

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，如果我嘗試遍歷查詢：

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

它會通過數據庫中的訂單ID顯示記錄！？

我該如何解決這個問題？

Answer 1

您正在訂購location asc，但location未在您的查詢中定義。您將列location重新命名爲Location_location，因此您應該訂購Location_location asc。

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
