aggregate function done wrongly
As far as I know, this error means sql couldn't find the placeName ,picURL columns which is selected by the group.

So you will get this error.
I suggest you could write a database demo to us and write a result demo to us, so that it will be more easily for us to find the solution to achieve your requirement.
The result I want to achieve：
