Description:
>> In the second query, we could not have written SELECT * FROM test1 GROUP
BY x, because there is no single value for the column y that could be
associated with each group. The grouped-by columns can be referenced in the
select list since they have a single value in each group.
I think you mis-copied the query - the one on the page has “select x”, not “select *”.
