＃1064 - 您的SQL語法有錯誤;檢查對應於您MariaDB的服務器

Question

我想我的SQL服務器上運行下面的查詢手冊：我已經在我的e_store數據庫品牌和類別表

CREATE TABLE `e_store`.`products`(
    `id` INT UNSIGNED NOT NULL AUTO_INCREMENT , 
    `name` VARCHAR(250) NOT NULL , 
    `brand_id` INT UNSIGNED NOT NULL , 
    `category_id` INT UNSIGNED NOT NULL , 
    `attributes` JSON NOT NULL , 
    PRIMARY KEY(`id`) , 
    INDEX `CATEGORY_ID`(`category_id` ASC) , 
    INDEX `BRAND_ID`(`brand_id` ASC) , 
    CONSTRAINT `brand_id` FOREIGN KEY(`brand_id`) REFERENCES `e_store`.`brands`(`id`) ON DELETE RESTRICT ON UPDATE CASCADE , 
    CONSTRAINT `category_id` FOREIGN KEY(`category_id`) REFERENCES `e_store`.`categories`(`id`) ON DELETE RESTRICT ON UPDATE CASCADE 
); 

。

，但我得到了以下錯誤：

#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'JSON NOT NULL , 
    PRIMARY KEY(`id`) , 
    INDEX `CATEGORY_ID`('category_id' ' at line 6 

Answer 1

你已經在你的索引定義，而不是反引號給予單引號

試試這個：

CREATE TABLE `e_store`.`products`(
    `id` INT UNSIGNED NOT NULL AUTO_INCREMENT , 
    `name` VARCHAR(250) NOT NULL , 
    `brand_id` INT UNSIGNED NOT NULL , 
    `category_id` INT UNSIGNED NOT NULL , 
    `attributes` JSON NOT NULL , 
    PRIMARY KEY(`id`) , 
    INDEX `CATEGORY_ID`(`category_id` ASC) , -- Changed single quotes to backticks 
    INDEX `BRAND_ID`(`brand_id` ASC) , -- Changed single quotes to backticks 
    CONSTRAINT `brand_id` FOREIGN KEY(`brand_id`) REFERENCES `e_store`.`brands`(`id`) ON DELETE RESTRICT ON UPDATE CASCADE , 
    CONSTRAINT `category_id` FOREIGN KEY(`category_id`) REFERENCES `e_store`.`categories`(`id`) ON DELETE RESTRICT ON UPDATE CASCADE 
); 

Answer 2

我覺得你得到錯誤爲JSON數據類型。

對於Mysql 5.7，您可以從下面的鏈接獲得幫助。

https://dev.mysql.com/doc/refman/5.7/en/json.html

您可以檢查vesrion使用下面的查詢。

select version() as 'mysql version' 

Answer 3

「JSON」在服務器中被解析。 JSON是分歧點之一。

MySQL 5.7引入了JSON數據類型，它符合您的語法。

MariaDB 10.0.16引入了一個ENGINE=CONNECT table_type=JSON，它與您嘗試的語法不匹配。
