mysql - 创建表抛出错误

Question

您好我正在尝试在 Mysql 中使用 SQL 创建一个表，但我不断收到错误消息。这是我的代码：

USE e-commerce
  CREATE TABLE `categories` (
`id` SMALLINT NOT NULL AUTO_INCREMENT,
`category` VARCHAR( 30) NOT NULL,
PRIMARY KEY (`id`),
UNIQUE KEY `category` (`category`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8;

当我尝试在 phpmyadmin SQL 控制台中运行它时，我收到此错误：

#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 `categories` ( `id` SMALLINT NOT NULL AUTO_INCREMENT, `category` ' at line 2

我究竟做错了什么？

Answer 1

后面加分号use

USE e-commerce;
CREATE TABLE `categories` (
  `id` SMALLINT NOT NULL AUTO_INCREMENT,
  `category` VARCHAR( 30) NOT NULL,
  PRIMARY KEY (`id`),
  UNIQUE KEY `category` (`category`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8;

Answer 2

缺少分号

 USE e-commerce;
  CREATE TABLE `categories` (
`id` SMALLINT NOT NULL AUTO_INCREMENT,
`category` VARCHAR( 30) NOT NULL,
PRIMARY KEY (`id`),
UNIQUE KEY `category` (`category`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8;

Answer 3

在您的代码中，您有 2 个查询。您应该始终以分号结束查询。

所以尝试以下

USE e-commerce;
CREATE TABLE `categories` (
`id` SMALLINT NOT NULL AUTO_INCREMENT,
`category` VARCHAR( 30) NOT NULL,
PRIMARY KEY (`id`),
UNIQUE KEY `category` (`category`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8;
