Thank you!
Seems to be related to MDEV-26407 also.
Repeatable on 10.2-10.9

CREATE TABLE t1 ( v1 INT  PRIMARY KEY );
 
INSERT t1  VALUES (1) , (2) ;
 
ALTER TABLE t1 ADD ( v4 INT AS (cast(case dayname('x') when 'x' then right('',78) end as time))) ;
 
UPDATE t1  SET v1 = v1 ;
 
SELECT * FROM t1 WHERE v1 LIKE 'x' ORDER BY COALESCE ( 'x' ) ;
