Sql 蜂巢-总的来说是其他的

以下内容在RDBMS数据库上作为SQL正常运行。但是，这无法在hive上运行

SELECT
        entry_date,
        customer,
        cust_loc,
        SUM(run_time) AS TOTAL_RUN,
        SUM(CASE WHEN run_time BETWEEN 10000 AND 20000 THEN entry_date ELSE 0 END) AS SLOT_1,
        SUM(CASE WHEN run_time BETWEEN 200001 AND 30000 THEN entry_date ELSE 0 END) AS SLOT_2,
        SUM(CASE WHEN run_time BETWEEN 31000 AND 40000 THEN entry_date ELSE 0 END) AS SLOT_3
FROM
        cust_run_details
WHERE
        app_env IN ('a','b')
        AND entry_date = '2015-02-01'
        AND flag_set='U'
GROUP BY
        customer,
        customer,
        cust_loc

在配置单元上运行时出现的错误是

FAILED: SemanticException [Error 10016]: Line 6:80 Argument type mismatch '0': The expression after ELSE should have the same type as those after THEN: "string" is expected but "int" is found

如何将其转换为蜂巢等效物？请告诉我这里有什么想法可以帮助我

将总数改为COUNT并去掉“ELSE 0”。花了很长时间才到达那里。唉

SELECT
        entry_date,
        customer,
        cust_loc,
        SUM(run_time) AS TOTAL_RUN,
        COUNT(CASE WHEN run_time BETWEEN 10000 AND 20000 THEN entry_date END) AS SLOT_1,
        COUNT(CASE WHEN run_time BETWEEN 200001 AND 30000 THEN entry_date END) AS SLOT_2,
        COUNT(CASE WHEN run_time BETWEEN 31000 AND 40000 THEN entry_date END) AS SLOT_3
FROM
        cust_run_details
WHERE
        app_env IN ('a','b')
        AND entry_date = '2015-02-01'
        AND flag_set='U'
GROUP BY
        customer,
        customer,
        cust_loc

假设

entry\u date

是

date

，您可能不想

sum（）

它。如果需要不同范围内的运行时间总和，则需要一个

选择
，如下所示：

 SELECT entry_date,
        customer,
        cust_loc,
        SUM(run_time) AS TOTAL_RUN,
        SUM(CASE WHEN run_time BETWEEN 10000 AND 20000 THEN run_time ELSE 0 END) AS SLOT_1,
        SUM(CASE WHEN run_time BETWEEN 200001 AND 30000 THEN run_time ELSE 0 END) AS SLOT_2,
        SUM(CASE WHEN run_time BETWEEN 31000 AND 40000 THEN run_time ELSE 0 END) AS SLOT_3

如果需要不同范围内的运行时间计数，则：

 SELECT entry_date,
        customer,
        cust_loc,
        SUM(run_time) AS TOTAL_RUN,
        SUM(CASE WHEN run_time BETWEEN 10000 AND 20000 THEN 1 ELSE 0 END) AS SLOT_1,
        SUM(CASE WHEN run_time BETWEEN 200001 AND 30000 THEN 1 ELSE 0 END) AS SLOT_2,
        SUM(CASE WHEN run_time BETWEEN 31000 AND 40000 THEN 1 ELSE 0 END) AS SLOT_3

如果
entry\u date
可能是
NULL
并且您希望忽略这些记录，那么您可以在
WHEN
条件中包含
并且entry\u date不为NULL
。
将总和更改为COUNT并去掉“ELSE 0”。花了很长时间才到达那里。唉……谢谢你，戈登。谢谢你的帮助。
