Incorrect table definition; there can be only one auto column and it must be defined as a key

Incorrect table definition; there can be only one auto column and it must be defined as a key

翻译：不正确的表定义,只能有一个自增列和它必须被定义为一个键

那么我们建表的时候将自增列要设置成主键咯，多个主键的时候，我们应该将自增列放在首位，如：primary key(AUTO_COL，..........)

这样子就好啦。
