进行逻辑检查分组查询结果

Question

我有数据设置如下，

job_id | status 
-------|------- 
    100 | 0 
    100 | 0 
    102 | 1 
    102 | 0 
    104 | 1 
    104 | 1 
--------------- 

查询处理数据

SELECT job_id, (CASE WHEN FIND_IN_SET(0, GROUP_CONCAT(status)) > 0 THEN FALSE ELSE TRUE END) AS isfinished 
FROM mytable 
GROUP BY job_id 

，其结果是

job_id | isfinished 
-------|----------- 
    100 |  0 
    102 |  0 
    104 |  1 
------------------- 

有任何人都做过这个？也许有更好的方法。

Answer 1

它看起来像你想看看如果最小值是大于0

SELECT job_id, min(status) > 0 AS isfinished 
FROM mytable 
GROUP BY job_id;
