[英]How to order varchar as int in Symfony2 Doctrine2?
I have the following code: 我有以下代码:
$entity = $em->getRepository('MyBundle:MyEntity')
->createQueryBuilder('q')
->...
->orderBy('q.varcharCol')
->getQuery()
->getResult();
varcharProp
is a varchar column containing values such as: 10, 10a, 101, 20, 300, 20b, 21, 200. I want to sort my entity by varcharProp but casting it as integer and I must do this ordering inside the query because I'm limiting the results. varcharProp
是一个包含以下值的varchar列:10,10a,101,20,300,20b,21,200。我想通过varcharProp对我的实体进行排序,但是将它作为整数进行排序,我必须在查询中进行此排序,因为我限制结果。
It's possible to do something like this in Doctrine2? 在Doctrine2中可以做这样的事情吗?
entity->orderBy('ABS(q.varcharCol)')
Or changing varcharProp
column type? 或者更改
varcharProp
列类型?
The best way to approach this is adding a select
with the orderBy
expression as a hidden column. 解决这个问题的最佳方法是使用
orderBy
表达式添加一个select
作为隐藏列。 I mean: 我的意思是:
$entity = $em->getRepository('MyBundle:MyEntity')
->createQueryBuilder('q')
->addSelect('ABS(q.varcharCol) AS HIDDEN foo')
->...
->orderBy('foo')
->getQuery()
->getResult();
