create table ttest (v1 int, v2 int);
insert into ttest values(1, 2), (4,6), (1, 7);

mysql> select distinct v1 from ttest where v1=2 order by v2;
ERROR 3065 (HY000): Expression #1 of ORDER BY clause is not in SELECT list, references column 'test.ttest.v2' which is not in SELECT list; this is incompatible with DISTINCT
mysql> select distinct 1 from ttest order by v1;
ERROR 3065 (HY000): Expression #1 of ORDER BY clause is not in SELECT list, references column 'test.ttest.v1' which is not in SELECT list; this is incompatible with DISTINCT

the same is as crdb, postgres, mysql, even constant here won't be passed either.
