Question

当我尝试在SQL中创建TABLE时，我收到以下错误。

phpMyAdmin的版本我使用它4.2.7.1，它说它是最新的。

有人可以帮忙吗？我无法发现错误？我查看了与错误1064相关的类似问题，但没有快乐

MySQL说：文档

#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 ''categories' (
    'id' SMALLINT UNSIGNED NOT NULL AUTO_INCREMENT,
    'catego' at line 1

Answer 1

从字段名称中删除单引号字符

Answer 2

你需要使用back-ticks`（键盘上的1键旁边）而不是'引号。这对我有用：

CREATE TABLE `categories` (
   `id` SMALLINT UNSIGNED NOT NULL AUTO_INCREMENT,
   `category` VARCHAR(45) NOT NULL,
   PRIMARY KEY (`id`),
   UNIQUE INDEX `category_UNIQUE` (`category` ASC)
) ENGINE = InnoDB DEFAULT CHARSET=utf8;

Answer 3

用'。

替换'表名和字段名周围的'字符

然后会出现更多语法错误 - 例如，'users'表周围有不需要的括号。此外，当您创建“订单”表时，它在用户上有一个外键，但稍后会声明用户。

＃1064您的SQL语法有错误;
