[英]doctrine query builder select from table which is not entity table
I am struggling to find a way to use query builder to select data from a table which is not a table of some entity. 我正在努力找到一种方法来使用查询构建器从表中选择数据,该表不是某个实体的表。 method ->from() takes only class name (entity name) as a parameter.
method - > from()仅将类名(实体名称)作为参数。 something like:
就像是:
$qb->select('t.id')
->from('table_not_entity_name')
->andWhere('t.isActive = :isActive')
->setParameter('isActive', 1);
I also need to join a table of entity to an another table. 我还需要将实体表连接到另一个表。
$qb->select('category.id')
->join("t.table_name", 'category')
->distinct();
Is there a way? 有办法吗?
Not with DQL, you can use NativeQuery . 不使用DQL,您可以使用NativeQuery 。
The comment in function 'from()' at QueryBuilder class says that: QueryBuilder类中函数'from()'中的注释表示:
Creates and adds a query root corresponding to the entity identified by the given alias, forming a cartesian product with any existing query roots.
创建并添加与给定别名标识的实体对应的查询根,形成具有任何现有查询根的笛卡尔积。
Is specific for an entity. 特定于实体。
