> In current version following query works:
> {code:java}
> select * from values(1,2) group by grouping sets (col1,col2,col1+col2) order by `(col1#x + col2#y)`
> {code}
> where #x and #y are expression IDs generated for related attributes. This isn't right as it leads to nondeterministic behavior (queries that pass would fail next time). In this issue I propose that we fix that.
