javax.persistence.NoResultException: No entity found for query

Question

Before I posted this question, I already looked this, but I couldn\'t get what I was looking for.

I know that for the query I wrote there may exist only one row or n

Answer 1

You mentioned getting the result list from the Query, since you don't know that there is a UniqueResult (hence the exception) you could use list and check the size?

if (query.list().size() == 1) 

Since you're not doing a get() to get your unique object a query will be executed whether you call uniqueResult or list.
