带有多维数据集错误的SQL查询

例如，我有一张订单表

订单{o_orderkey，o_custkey，o_orderstatus，o_totalprice，o_orderdate，o_orderpriority，o_clerk…诸如此类…}

我试过了

SELECT o_orderkey, o_orderdate, sum(o_totalprice)
FROM orders
GROUP BY CUBE (o_orderkey, o_orderdate)
ORDER BY o_orderkey, o_orderdate;

但它给了我一个错误：

错误：编译语句时出错：失败：ParseException行4:5无法识别“多维数据集”（表达式规范中的“o_orderkey”（状态=42000，代码=40000）附近的输入

---

所以我找到了问题的答案，现在我有了第二张桌子

行项{l_orderkey，l_suppkey和…等等…}

第一个表通过orderkey字段链接到此行项目表

所以我想找到这两个职员（o_职员）订购的零件总数

o#u clerk='clerk'000000522'或o#u clerk='clerk'000000154'per

订单日期（o_orderdate），每个suppkey（l_suppkey）

这是我的工作，但我不确定是否正确：

SELECT o_clerk, o_orderdate, l.l_suppkey, sum(l.l_quantity) as TotalParts
FROM orders as o, lineitem as l
WHERE o.o_orderkey = l.l_orderkey
AND o.o_clerk='Clerk#000000522' OR o.o_clerk='Clerk#000000154'
GROUP BY o_clerk, o_orderdate, l.l_suppkey WITH CUBE
ORDER BY o_orderdate, l.l_suppkey;

---

在Hive中，您可以将其表述为：

SELECT o_orderkey, o_orderdate, sum(o_totalprice)
FROM orders
GROUP BY o_orderkey, o_orderdate CUBE
ORDER BY o_orderkey, o_orderdate;

是的，我意识到我必须按o_orderkey、o_orderdate和多维数据集进行分组；是的，我意识到我必须按o_orderkey、o_orderdate和多维数据集进行分组；
