. If these columns are not explicitly defined as not null, MySQL will implicitly define these columns. 3. The primary key is also an index: As I have already said, the primary key is actually an index. Even in MySQL terminology, the "key" is equivalent to "Index". Therefore, the "foreign key" must be set to "Index" first ". Therefore, the primary key should be the same as the index, which can act on individual fields and multiple fields. For example, if I live in Room 3, Room

But using NFS only needs to be placed on a , then a is shared with B and C . At the time of the visit,B and C go through the network to a
