Question

我需要使用php创建表而不使用phpmyadmin但是第二个块正在执行Table user wasn't created问题可以通过语句CREATE TABLE....连接到数据库成功。谢谢你的帮助

if ( (mysqli_query( $mysqli_connect, "CREATE TABLE IF NOT EXISTS user" .
                "(user_id int(11) NOT NULL AUTO_INCREMENT,
                              user_name varchar(64) NOT NULL,
                              user_password_hash varchar(255)NOT NULL,
                              user_email varchar(64) NOT NULL,
                              user_active_status BIT(1) NOT NULL DEFAULT '0' COMMENT 'BIT -bytes representation',
                              user_activation_hash varchar(40) DEFAULT NULL,
                              user_password_reset_hash varchar(40) DEFAULT NULL,
                              user_password_reset_timestamp BIT(20) DEFAULT NULL,
                              user_rememberme_token varchar(64) DEFAULT NULL,
                              user_failed_logins BIT(1) NOT NULL DEFAULT '0',
                              user_last_failed_login int(10) DEFAULT NULL,
                              user_registration_datetime datetime NOT NULL DEFAULT '0000-00-00 00:00:00' COMMENT 'YYYY-MM-DD HH-MM-SS',

                              PRIMARY KEY(user_id),
                              UNIQUE KEY user_name (user_name),

 )ENGINE=MyISAM AUTO_INCREMENT=1 DEFAULT CHARSET=utf8 COMMENT='wordpress uses InnoDB)" ) ) ) {
    echo "Table useer was created";
} else {
    echo "Table user wasn't created";
}

您应该看到使用mysqli_error()

的错误

我在phpmyadmin中运行此问题时出现了一些问题（email拼写错误，评论缺少引号）

下一个查询有效

CREATE TABLE IF NOT EXISTS user (user_id int(11) NOT NULL AUTO_INCREMENT,
                          user_name varchar(64) NOT NULL,
                          user_password_hash varchar(255)NOT NULL,
                          user_email varchar(64) NOT NULL,
                          user_active_status BIT(1) NOT NULL DEFAULT 0 COMMENT 'BIT -bytes representation',
                          user_activation_hash varchar(40) DEFAULT NULL,
                          user_password_reset_hash varchar(40) DEFAULT NULL,
                          user_password_reset_timestamp BIT(20) DEFAULT NULL,
                          user_rememberme_token varchar(64) DEFAULT NULL,
                          user_failed_logins BIT(1) NOT NULL DEFAULT 0,
                          user_last_failed_login int(10) DEFAULT NULL,
                          user_registration_datetime datetime NOT NULL DEFAULT '0000-00-00 00:00:00' COMMENT 'YYYY-MM-DD HH-MM-SS',
                          user_registration_ip varchar(39) NOT NULL DEFAULT '0.0.0.0',
                          PRIMARY KEY(user_id),
                          UNIQUE KEY user_name (user_name),
                          UNIQUE KEY user_mail (user_email)  
)ENGINE=MyISAM AUTO_INCREMENT=1 DEFAULT CHARSET=utf8 COMMENT='wordpress uses InnoDB'
