＃1064您的SQL語法錯誤;

Question

當我嘗試在SQL中創建TABLE時，出現以下錯誤。

phpMyAdmin的版本我用它4.2.7.1它說它是最新的。

任何人都可以幫忙嗎？我找不到錯誤？我特地在與錯誤1064類似的問題，但沒有喜悅

MySQL表示：文件

#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

您需要使用卸下的字段名的單引號字符（我鍵盤上的1鍵旁邊）而不是'引號'。這適用於我：

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'替換包圍表名和字段名的字符。

會出現一些更多的語法錯誤 - 例如，在'用戶'表中有不需要的括號。 另外，當您創建'orders'表時，它對用戶有一個外鍵，但用戶稍後會被聲明。
