我在 Zend 中使用 Doctrine 1.1.我正在尝试编写一个查询,该查询将返回在某一列中具有空值的记录.
I am using Doctrine 1.1 in Zend. I am trying to write a query that will return records that have a null value in a certain column.
$q = Doctrine_Query::create()
->select('a.*')
->from('RuleSet a')
->where('a.vertical_id = ?', null);
$ruleset_names_result = $q->execute(array(), Doctrine::HYDRATE_ARRAY);
我在规则集表中有三个记录,它们在 vertical_id 列中有一个 NULL 值,但查询没有找到这些记录.
I have three records in the ruleset table which have a NULL value in the vertical_id column yet the query doest not find these.
感谢您的帮助.

我在 symfony 中使用学说,我就是这样做的:
I use doctrine with symfony, and this is how I do:
where('a.vertical_id is NULL');
