agg1,
sum(o_totalprice) as sum_total,
max(o_totalprice) as max_total,
min(o_totalprice) as min_total,
count(*) as count_all,
bitmap_union(to_bitmap(case when o_shippriority > 1 and o_orderkey
IN (1, 3) then o_custkey else null end)) cnt_1,
bitmap_union(to_bitmap(case when o_shippriority > 2 and o_orderkey
IN (2) then o_custkey else null end)) as cnt_2
from lineitem_1
inner join orders_1
on lineitem_1.l_orderkey = orders_1.o_orderkey
where lineitem_1.l_shipdate >= "2023-10-17"
group by l_orderkey, l_partkey, l_suppkey, o_orderkey, o_custkey
**mv_2**
select l_orderkey, l_partkey, l_suppkey, o_orderkey, o_custkey,
ps_partkey, ps_suppkey,
t.agg1 as agg1,
t.sum_total as agg3,
t.max_total as agg4,
t.min_total as agg5,
t.count_all as agg6,
cast(sum(IFNULL(ps_suppkey, 0) * IFNULL(ps_partkey, 0)) as
decimal(28, 8)) as agg2
from ${mv_1} as t
inner join partsupp_1
on t.l_partkey = partsupp_1.ps_partkey and t.l_suppkey =
