    Description

      This problem is similar to MDEV-11514, but now for the CASE operator.

      SELECT
      		 
        CASE TIME'10:20:30'
      		 
          WHEN 102030 THEN 'one'
      		 
          WHEN TIME'10:20:31' THEN 'two'
      		 
        END AS good,
      		 
        CASE TIME'10:20:30'
      		 
          WHEN 102030 THEN 'one'
      		 
          WHEN TIME'10:20:31' THEN 'two'
      		 
          WHEN TIMESTAMP'2001-01-01 10:20:32' THEN 'three'
      		 
        END AS bad;
      		 
      SHOW WARNINGS;


      +------+------+
      		 
      | good | bad  |
      		 
      +------+------+
      		 
      | one  | NULL |
      		 
      +------+------+


      +---------+------+------------------------------------+
      		 
      | Level   | Code | Message                            |
      		 
      +---------+------+------------------------------------+
      		 
      | Warning | 1292 | Incorrect datetime value: '102030' |
      		 
      +---------+------+------------------------------------+

      The expected result is to return "one" in both columns.
