创建表时会引发错误

Question

您好我想创建在MySQL使用SQL表，但我不断收到error.Here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; 

当我试图在phpMyAdmin SQL控制台运行此得到这个错误：

#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 

我在做什么错？

Answer 1

添加分号后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

在你的代码有2个查询。你应该总是用分号结束查询。

所以请尝试以下

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;
