蜂巢。用 vs Have 子句过度划分

Question

我有下表：

column0  column1      column2 column3 column4
sunny    hot         high    false   no
sunny    hot         high    true    no
overcast hot         high    false   yes
rainy    mild        high    false   yes
rainy    cool        normal  false   yes
rainy    cool        normal  true    no

我想使用 have-clause 和 OVER PARTITION BY 运行查询，我的查询是

SELECT column0,column1,column2,count(column0) OVER (PARTITION BY column2) AS cnt FROM FF_weatherdatase1  where column0="sunny"  having cnt>8

但蜂巢显示：

 HAVING specified without GROUP BY error.

请提供在不按条件分组的情况下使用 over partition by condition 运行 having 子句的方法，提前致谢。

Answer 1

HAVING 只能与 GROUP BY 一起使用。对于您的查询，您可以在括号外使用where 条件。

SELECT *
FROM   (SELECT column0,
               column1,
               column2,
               COUNT(column0)
                 OVER (
                   PARTITION BY column2) AS cnt
        FROM   ff_weatherdatase1
        WHERE  column0 = 'sunny') w
WHERE  cnt > 8
