Question

我有一张名为＆＃39; option_product＆＃39;在MYSQL上

Id  id_product   id_option   id_value
1   1             34          77
2   2             34          74
3   1             2           12          
4   2             2           10
5   3             2           18

我想做那样的事情

select id from option_product where 

id_option = 34 and id_value = 77

and 

(id_option=2 and id value= 12 or id_option=2 and id value= 5)

我该怎么做？

查询应返回包含所有条件的id_product if（id_option = 34和id_value = 77）和（id_option = 2且id_value = 12或id_option = 2且id_value = 10）它将返回id_product = 1

Answer 1

Select id
From option_product
Where (id_option = 34 And id_value = 77) Or (id_option = 2 And id_value In (12, 5))

这将获得包含（option_id，id_value） - ＆gt;的行。（34,77），（2,12）和（2,5）

Answer 2

我认为你的真正含义是：

select id from option_product where (id_option = 34 and id_value = 77)
OR (id_option=2 and id value= 12)
OR (id_option=2 and id value= 5)

Answer 3

试试这个：

  select id from option_product where 
  (id_option = 34 and id_value = 77)
  or
  (id_option=2 and (id_value= 12 or id_value= 5) )

多个在同一个表mysql中的位置？
