[英]Column 'available_for_order' in where clause is ambiguous
I'm strugling with this query within prestashop , i know it could be easily fixed by changing to sa.available_for_order
but this way it breaks the logic of other core files , is there any other way around to fix this without renaming available_for_order
to sa.available_for_order
, 我在prestashop中处理此查询,我知道可以通过更改为sa.available_for_order
来轻松解决它,但是这样做会破坏其他核心文件的逻辑,是否有其他方法可以解决此问题而无需将available_for_order
重命名为sa.available_for_order
,

PRESTASHOP 前期
public function __construct()
{
parent::__construct();
$this->_select .= ',sa.`available_for_order` AS `available_for_order`, ';
$this->fields_list['sa!available_for_order'] = array(
'title' => $this->l('Available for order'),
'width' => 90,
'active' => 'available_for_order',
'filter_key' => 'sa!available_for_order',
'type' => 'bool',
'align' => 'center',
'orderby' => false
);
}
The column available_for_order
must be in more than one of the tables. 列available_for_order
必须在多个表中。 Just qualify the column name, as you do in the select
: 就像在select
一样,只需限定列名:
WHERE 1 AND sa.available_for_order = 1
------------^
Modify your fields list to use having filter. 修改您的字段列表以使用具有过滤器。
$this->fields_list['available_for_order'] = array(
'title' => $this->l('Available for order'),
'width' => 90,
'active' => 'available_for_order',
'filter_key' => 'available_for_order',
'havingFilter' => true,
'type' => 'bool',
'align' => 'center',
'orderby' => false
);
This will use HAVING
instead of WHERE
in query. 这将在查询中使用HAVING
而不是WHERE
。
WHERE
clause does not work on column aliases but HAVING
does. WHERE
子句不适用于列别名,但HAVING
可以。
