    Description

      Another different behaviour regarding trailing spaces between InnoDB and Columnstore.

      Coliumnstore engine:

      CREATE TABLE `save` (
      		 
      `code` varchar(255) DEFAULT NULL
      		 
      ) ENGINE=Columnstore DEFAULT CHARSET=utf8
      		 
      ;
      		 
       
      		 
      INSERT INTO save
      		 
      VALUES
      		 
      ('15 hours '),
      		 
      ('14 hours');
      		 
       
      		 
      select code
      		 
      from save
      		 
      where code IN ('15 hours ', '14 hours');


       select code
      		 
        from save
      		 
       where code IN ('15 hours ', '14 hours');
      		 
      +----------+
      		 
      | code     |
      		 
      +----------+
      		 
      | 14 hours |
      		 
      +----------+
      		 
      1 row in set, 1 warning (0.08 sec)

      InnoDB:

      DROP table if exists `save2`;
      		 
       
      		 
      CREATE TABLE `save2` (
      		 
      `code` varchar(255) DEFAULT NULL
      		 
      ) ENGINE=Innodb DEFAULT CHARSET=utf8
      		 
      ;
      		 
       
      		 
      INSERT INTO save2
      		 
      VALUES
      		 
      ('15 hours '),
      		 
      ('14 hours');
      		 
       
      		 
      select code
      		 
      from save2
      		 
      where code IN ('15 hours ', '14 hours');


      select code from save2 where code IN ('15 hours ', '14 hours');
      		 
      +-----------+
      		 
      | code      |
      		 
      +-----------+
      		 
      | 15 hours  |
      		 
      | 14 hours  |
      		 
      +-----------+
