I want to get all Images not used by current ItemID. The this subquery but it also always returns duplicate Images:
EDITED
select Images.ImageID, Images.ItemStatus, Images.UserName, Images.Url,
Image_Item.ItemID, Image_Item.ItemID
from Images
left join (select ImageID, ItemID, MAX(DateCreated) x
from Image_Item
where ItemID != '5a0077fe-cf86-434d-9f3b-7ff3030a1b6e'
group by ImageID, ItemID
having count(*) = 1)
image_item on Images.imageid = image_item.imageid
where ItemID is not null
I guess the problem is with the subquery which I can't avoid duplicate rows:
select ImageID, ItemID, MAX(DateCreated) x
from Image_Item
where ItemID != '5a0077fe-cf86-434d-9f3b-7ff3030a1b6e'
group by ImageID, ItemID
having count(*) = 1
Result:
