Yes, the DEFAULT doesn't apply. However, shouldn't MySQL
raise an exception because '' isn't a valid value for this ENUM
The value may also be the empty string ("") or NULL under certain
If you insert an invalid value into an ENUM (that is, a string not
present in the list of allowed values), the empty string is inserted
instead as a special error value. This string can be distinguished from
a 'normal' empty string by the fact that this string has the numerical
value 0. More about this later.
If an ENUM is declared NULL, NULL is also a legal value for the column,
and the default value is NULL. If an ENUM is declared NOT NULL, the
default value is the first element of the list of allowed values.
