mysql - 如何从两个查询中只返回一个查询结果

Question

我目前的sql查询如下。我尝试了一些联合查询，但没有成功。

Select file_path
from images
where image_id In (
  Select image_id
  from temp_images
  where object_uid IN (
    Select  object_uid
    from object_table
    where object_status = 2 and object_place like "%some_keyword%"))`


Select object_uid, object_utitle
from object_table
where object_status = 2 and object_place like "%some_keyword%"`

两个查询可能返回许多行。我想像这样返回 file_path 和 object_uid 。

-图像 ID |对象_uid |对象_标题

-img1 |对象1 |标题1

-img2 |对象2 |标题2

-img2 |对象2 |标题3

有什么办法可以做到这一点吗？

试试这个:

Select a.file_path, b.object_uid, b.object_utitle
from images a, (Select  object_uid, object_utitle
    from object_table
    where object_status = 2 and object_place like "%some_keyword%") b
where image_id In (
  Select image_id
  from temp_images
  where object_uid IN (b.object_uid) )
