Query result type inference often not working with getOneOrNullResult

[janedbal]

See failures in #270, all the new getOneOrNullResult are infered as mixed even though the getResult works fine.

Hi @janedbal

Currently, Query result type inference supports only HYDRATE_OBJECT mode. What happens here is that we don't know the hydration mode of getOneOrNullResult() when called with 0 arguments, because it defaults to $this->_hydrationMode.

getResult() is different because its default hydration mode is HYDRATE_OBJECT.

One way to get type inference out of getOneOrNullResult() is to specify the hydration mode when calling it: getOneOrNullResult(Query::HYDRATE_OBJECT).

(See #232 (comment) for details on how each getResult() variant is supported.)

I see, thanks for response, I'll force passing hydration type to getOneOrNullResult in our codebase to make it analysable.
