mysql - Exclude duplicate values in one table and return the remaining -

i have table so:

table: album_image(album_id, image_id)  album_id    image_id ---------------------------- 87          2326 87          2325 86          2325 85          5689 89          56 

having 2 album id's (let's 87 , 86), want extract image_id not in 2 albums.

so, example, if have album_id 87 , 86, should return image_id : 2326

how go doing query?

as per requirement looks need find image either on album_id 86 or 87 not both, , done using group by , having count

select  image_id album_image  album_id in (87,86)  group image_id having count(*)=1 ;
