Using asterisk in JOIN query

Hi,

I've encountered a problem with JOIN queries like this:

```
SELECT s.*, cat.DisplayName
FROM shops s
JOIN shops cat ON s.id = cat.parentId
WHERE s.parentId = '123123'
```

Here I expect `s.*` to be recognized as "all fields from index s", but it gets recognized as field name.

Maybe there is some workaround for this case?
