sql - SQL 日语法在 AWS Athena 上不起作用

Question

完整的 SQL 新手。我正在尝试在 AWS Athena 上执行以下 TPC-H 查询：

select
        l_returnflag,
        l_linestatus,
        sum(l_quantity) as sum_qty,
        sum(l_extendedprice) as sum_base_price,
        sum(l_extendedprice * (1 - l_discount)) as sum_disc_price,
        sum(l_extendedprice * (1 - l_discount) * (1 + l_tax)) as sum_charge,
        avg(l_quantity) as avg_qty,
        avg(l_extendedprice) as avg_price,
        avg(l_discount) as avg_disc,
        count(*) as count_order
from
        lineitem
where
        l_shipdate <= date '1998-12-01' - interval ':1' day (3)
group by
        l_returnflag,
        l_linestatus
order by
        l_returnflag,
        l_linestatus;

不幸的是，雅典娜不理解这个语法：l_shipdate <= date '1998-12-01' - interval ':1' day (3) 我也不知道。这是想做什么？
