I known that in sql statement the latest reply can be get by adding “order by created DESC limit 0,1”
But how can i get it using QueryBuilder?
I have refered to the document of QueryBuilder . There is no limit() function.
Just use ->setMaxResults(1) to say “limit” with doctrine
And the doc’: http://www.doctrine-project.org/docs/orm/2.1/en/reference/query-builder.html#limiting-the-result ^^
But in this case you should use ->getSingleResult() instide of ->getResult(), without using limit. (It’s more appropriated !)
