> We saw couple of issues with aliases in multi fact queries.
> * cube select func1(col1), func2(col1), m1,m2 from cube where
> time_range_in(dt, now.day - 2days, now) writes the query as follows :
> select COALESCE(mq1.col1, mq2.col1) col1, COALESCE(mq1.col1, mq2.col1) col1,
> mq1.m1, mq2.m2 from
> (select func1(col1) col1, func2(col1) col1, m1 from fact1 where ...) mq1
> full outer join
> (select func1(col1) col1, func2(col1) col1, m2 from fact2 where ...) mq2
> on
> mq1.col1 <=> mq2.col1 and mq1.col1 <=>mq2.col1
> * Another was the case of the alias of the column is same as the field
> selected.
