Can a set in MySQL be 0?

Can a set in MySQL be 0?

From stackoverflow

• Sure, why not?

  CREATE TABLE t_set (id INT NOT NULL PRIMARY KEY, value SET('one', 'two'));
  
  INSERT
  INTO    t_set
  VALUES  (1, 1);
  
  SELECT  *
  FROM    t_set;
  
  
  id    value
  ----  ------
     1  one
  
  UPDATE  t_set
  SET     value = 0;
  
  SELECT  *
  FROM    t_set;
  
  id    value
  ----  ------
     1
  

• A SET is a string object that can have zero or more values, each of which must be chosen from a list of allowed values specified when the table is created. SET column values that consist of multiple set members are specified with members separated by commas (“,”). A consequence of this is that SET member values should not themselves contain commas.

  For example, a column specified as SET('one', 'two') NOT NULL can have any of these values:

  '' 'one' 'two' 'one,two'
