蜂巢：to_map 功能不起作用

Question

我在 hive 表中有以下数据；

select pid, year, catches  from fielding_s where  pid = 'zobribe01' group by id;

zobribe01       2006    [{"p1":52,"p2":50,"p3":1322,"p4":86}]

我想使用 to_map 函数将这些行合并到一个表中。我在查询下方运行，但它给了我以下错误。

select pid, to_map(year, catches) from fielding_s where  pid = 'zobribe01' group by pid;

失败：SemanticException [错误 10025]：第 1:12 行表达式不在 GROUP BY 键“捕获”中

Answer 1

从您的查询中删除group by 子句，然后尝试

select id, map(name, designation) b from snow
