好吧,从Oracle切割和粘贴并不总是很好;

VARCHAR2在MySQL中不作为数据类型存在.
NUMBER也没有.
CASCADE CONSTRAINTS似乎不适合作为修饰语DROP TABLE.

作为替代CASCADE CONSTRAINTS,您可以使用一个语句删除多个表DROP TABLE IF EXISTS a,b,c.不太一样,但是它会变得很好.

你想要的可能是什么样的;

drop table if exists member;

create table member (
  mid varchar(10) not null,
  email varchar(40) not null,
  fname varchar(20) not null,
  lname varchar(20) not null,
  street varchar(50) not null,
  city varchar(30) not null,
  state varchar(20) not null,
  zip numeric(5) not null,
  phone varchar(12),
  password varchar(20),
  primary key (mid)
);
