选择mysql组不工作

Question

我有一个选择mysql的问题，表是这样的：

id_type |  id_funz | state    
10           26        1
10           28        1
11           26        1  

我想选择id_type（with group by），他们（state_funz 26和28）在state = 1，实际上只有id_type = 10

为什么这不起作用？

SELECT *
FROM   table
WHERE
(id_funz = 26 AND state = 1) and ((id_funz= 28 AND state = 1)
group by id_type

非常感谢你

Answer 1

id_funz = 26和id_funz = 28不能同时发生。将您的代码更改为：

(id_funz = 26 AND state = 1) OR (id_funz= 28 AND state = 1)
