Mysql SQL多对多关系查询

我有很多对很多的关系

  table:  images    
  id  imageName  
   1    pic01
   2    pic02
   3    pic03    

  table:  imagesKeywords
  imageId  keywordId
   1        2
   1        3
   1        4
   2        3
   3        1
   3        4
   3        2

  table:  keywords
  id  keywordName  
   1    car
   2    tree
   3    cat
   4    phone

每个图像都有一些关键字，不同的图像可以有相同的关键字

我需要搜索图像，它们有一个特定的

关键字名称

示例1：搜索汽车和手机

结果应该是：pic03

示例2：搜索树和电话

结果应该是：pic01，pic03

据我所知，这应该是可行的：

select i.imageName as name from keywords k
join imagesKeywords iK on k.id = iK.keywordId
join images i on iK.imageId = i.id
group by i.imageName;

据我所知，这应该是可行的：

select i.imageName as name from keywords k
join imagesKeywords iK on k.id = iK.keywordId
join images i on iK.imageId = i.id
group by i.imageName;

一个可能的解决办法

with subquery as
       (select i1.imageName, k1.keywordName from keywords k1 join imagekeywords ik1 on k1.id=ik1.keywordId join images i1 on i1.id = ik1.imageId )    
 select a.imageName from subquery a join subquery b on a.imageName=b.imageName where a.keywordName ='car' and b.keywordName='phone';
