You can't always solve your problems by following an example. Sometimes you have to recognize the patterns, apply your own knowledge and extend the examples. The MySQL documentation, with its focus on examples instead of formal definitions, isn't the easiest for that, so I would strongly suggest learning SQL from a source that pays more attention to formal definitions.
