如何将 array<map<string,int>> 插入到配置单元 table 中？

Question

我有一个蜂巢table如下：

0: jdbc:hive2://Desktop:10000> desc tb_test2;
+-------------+-------------------------+----------+
|  col_name   |        data_type        | comment  |
+-------------+-------------------------+----------+
| name        | string                  |          |
| score_list  | array<map<string,int>>  |          |
+-------------+-------------------------+----------+

我想插入这样的数据：

A   [{"math":100,"english":90,"history":85}]  
B   [{"math":95,"english":80,"history":100}]  
C   [{"math":80,"english":90,"histroy":100}]

我试过这样：

0: jdbc:hive2://Desktop:10000> insert into tb_test2 values("A",Map("math":100,"english":90,"history":85));

但出现错误：

Error: Error while compiling statement: FAILED: ParseException line 1:42 cannot recognize input near '"math"' ':' '100' in constant (state=42000,code=40000)

Answer 1

我觉得应该用逗号，还要指定数组

insert into tb_test2 select "A", array(map("math",100,"english",90,"history",85)) from (select 1) x;
