Question

我已经创建了一个登录系统。我对MYSQL有一些了解，我想修改一大堆代码。

这是代码：

DROP TABLE IF EXISTS users;
DROP TABLE IF EXISTS Country;
CREATE TABLE Country(
    country_code                char(2) not null,
    country_name                varchar(60) not null,
    primary key(country_code)
)
CREATE TABLE users(
    pk_user                     int unsigned not null auto_increment,
    email                       varchar(120) not null,
    flname                      varchar(100) not null,
    password                    varchar(64) not null,
    country_code                char(2) not null,
    usr_ip                      varchar(15),
    usr_nmb_logins              int(10) unsigned not null default 0,
    usr_signup_date             timestamp not null default CURRENT_TIMESTAMP,
    usr_userid                  varchar(32),
    usr_confirm_hash            varchar(255) not null,                  # for the account confirmation
    usr_is_confirmed            tinyint(1) not null default 0,          # after confirming its set to 1
    usr_resetpassword_hash      varchar(255) not null,                  # when the user resets password (forgot password)
    usr_is_blocked              tinyint(1) not null default 0,          # blocked or not
    usr_is_admin                tinyint(1) not null default 0,          # admin or not
    foreign key(country_code)   references Country(country_code),
    unique index(email),
    primary key(pk_user)
)

还有大量的insert如下：

insert into Country(country_code,country_name) values("n","?");

这是第一个以相同格式提供的至少一百个。

这是PHPMyAdmin给我的错误：

#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'CREATE TABLE users(
    pk_user                     int unsigned not null auto_increment,
    ema' at line 6

但是当我拿出那个错误或修正它时，更多的出现并说实话我不知道该怎么做。

CREATE TABLE Country(
    country_code                char(2) not null,
    country_name                varchar(60) not null,
    primary key(country_code)
);
CREATE TABLE users(
    pk_user                     int unsigned not null auto_increment,
    email                       varchar(120) not null,
