               group_concat_merge(group_concat_state(o_orderstatus)),
               avg_merge(avg_state(l_linenumber)),
               max_by_merge(max_by_state(O_COMMENT,o_totalprice)),
               count_merge(count_state(l_orderkey)),
               
multi_distinct_count_merge(multi_distinct_count_state(l_shipmode))
               from lineitem
               left join orders 
               on l_orderkey = o_orderkey and l_shipdate = o_orderdate
               group by
               o_orderstatus,
               l_suppkey
               order by o_orderstatus;
