Symfony 2 - 从表中获取最后一个插入的行

Question

How can I rewrite this code in order to get last inserted record from the table?

$repository = $entityManager->getRepository('AdminBundle:MyTable');
$product = $repository->find($id);

I tried something like

$repository->findBy(array('id','DESC')->setMaxResults(1);

But it did not work for me.

Answer 1

You could get the latest record by using findBy() with order by and limit paramters

$results = $repository->findBy(array(),array('id'=>'DESC'),0,1);

• First argument is for filter criteria
• Second argument takes order by criteria
• Third argument is for limit
• Fourth argument sets offset

Note it will return you the results set as array of objects so you can get single object from result as $results[0]
