def init_column(name, default, *args)
  @original_default = default
  @default = nil if missing_default_forged_as_empty_string?
end

#missing_default_forged_as_empty_string? ⇒ Boolean

MySQL misreports NOT NULL column default when none is given. We can’t detect this for columns which may have a legitimate ” default (string, text, binary) but we can for others (integer, datetime, boolean, and the rest).

Test whether the column has default ”, is not null, and is not a type allowing default ”.

Returns:

  • (Boolean)
