Review Comment:
```
val aliases = expressions.collect {
case e: Alias => e
case u: UnresolvedAttribute => Alias(u, u.nameParts.last)()
}
```
Now this works:
`EXECUTE IMMEDIATE 'SELECT :parm' USING system.session.parm;`
But I am not sure if this is intended. If you use anything else with more
name parts it will autocreate an alias with the final part.
