Yeah, in the prior examples it worked because the group-by columns will determine the value of the exists - that was only true when the aggregates did not use any non-group-by columns of the table. When we do have an aggregate using a non-grouped column of the outer table it wouldn't work. This aggregate doesn't require any changes to avoid the invalid aggregation error, right? I think this is another reason to go towards something like wrapping expressions in any_value aggregate when needed. -- This is an automated message from the Apache Git Service.
