2022-09-07 mysql/stonedb-TPCH-Q20语句测试

摘要:

对TPCH的Q20语句进行测试, 并与MySql8/innodb做对比

Q20语句

select
  s_name,
  s_address
from
  supplier,
  nation
where
  s_suppkey in (
    select
      ps_suppkey
    from
      partsupp
    where
      ps_partkey in (
        select
          p_partkey
        from
          part
        where
          p_name like 'forest%'
      )
      and ps_availqty > (
        select
          0.5 * sum(l_quantity)
        from
          lineitem,partsupp
        where
          l_partkey = ps_partkey
          and l_suppkey = ps_suppkey
          and l_shipdate >= date '1994-01-01'
          and l_shipdate < date '1994-01-01' + interval '1' year
      )
  )
  and s_nationkey = n_nationkey
  and n_name = 'CANADA'
order by
  s_name;
