Original Pull Request: https://github.com/doctrine/orm/pull/151

State: closed
Merged: Yes

This branch does multiple things:

Fix how INDEX BY works with mixed results. The index is now on the top level, not inside the mixed result.
Add support for INDEX BY in scalar only queries.
```
SELECT u.id, u.name FROM User u INDEX BY u.id
```

The following BC Breaks had to be made:

The hydration format changed when using INDEX BY with either mixed or scalar only results.
ResultSetMapping::$indexByMap is now $dqlAlias => $columnName, not $dqlAlias => $fieldName anymore.

Todos:

Since Hydration uses 'scalars' internally, we should prevent that identification variable name from being used.
Array Hydration scalar only is missing.
Unit-tests for RSM changes, aswell as some more error conditions (Exceptions).
Scalar only array hydration for nested levels?

Please code review.
