> Select query can only support maximum 128 distinct expressions. Otherwise,
> you will be thrown ArrayIndexOutOfBoundsException. For a query like:
> select count(distinct c1), count(distinct c2), count(distinct c3),
> count(distinct c4), count(distinct c5), count(distinct c6), ....,
> count(distinct c128), count(distinct c129) from tbl_129columns;
> you will get error like:
