Answer 1

尽管您不能创建2个主键，但是可以将索引设置设置为“ Yes （无重复）”，这将防止输入2个相同的条目，并且可以提供更快的搜索速度。

Answer 2

You can select both fields, hold the shift key and then right click and choice primary key. This will make both keys primary key. Meaning the combination must always be unique, and I guess this should answer both questions.
