Instance Method Details

#default_specified? ⇒ Boolean

MySQL sinks the boat on this one. If no default is specified for a non-nullable column, then MySQL assigns an implicit default value. This makes it impossible to determine whether or not a default value has been specified for any non-nullable column without parsing the SHOW CREATE TABLE output, which is non-standard.

Returns:

• (Boolean)

Raises:

• (NotImplementedError)
