存储过程

Question

我已经声明了一个名为order_id的变量，我想为我尝试插入的顺序存储自动递增的id集。我在OUTPUT处收到语法错误。

我已经阅读了很多示例和我看到的内容，这是编写代码的正确方法。所有代码都在存储过程中。插入订单和其余的程序是有效的，除了我需要自动递增的id插入另一个表。

CREATE DEFINER=`name`@`%` PROCEDURE `conduct_order`(
    IN username_par VARCHAR(50), 
    IN addr_par VARCHAR(100),
    IN zip_par VARCHAR(45))
BEGIN
    DECLARE user_addr VARCHAR(100);
    DECLARE user_zip VARCHAR(45);
    DECLARE user_country VARCHAR(100);
    DECLARE user_phone VARCHAR(45);
    DECLARE user_email VARCHAR(45);
    DECLARE this_date VARCHAR(45);
    DECLARE temp INT;


    SET user_id = (SELECT id FROM customers WHERE username= username_par);
    SET user_addr = addr_par;
    SET user_zip = zip_par;
    SET user_country = (SELECT country FROM customers WHERE username=username_par);
    SET user_phone = (SELECT phone FROM customers WHERE username=username_par);
    SET user_email = (SELECT email FROM customers WHERE username=username_par);
    SET this_date = (SELECT CURDATE());

    INSERT INTO orders(
                    customer_id, 
                    customer_addr,
                    customer_phone, 
                    customer_email, 
                    order_date, 
                    order_state, 
                    customer_postalcode, 
                    customer_country)
            OUTPUT order_id INTO temp
            VALUES( 
                    user_id,
                    user_addr,
                    user_phone,
                    user_email,
                    this_date,
                    'not sent',
                    user_zip,
                    user_country);

    INSERT INTO order_items(order_id, product_id, amount)
    VALUES(
        (SELECT id FROM orders 
        WHERE   customer_id=user_id 
        AND     order_date=this_date
        AND     customer_addr=user_addr
        AND     customer_postalcode=user_zip
        AND     customer_country=user_country),
        (SELECT product_id FROM carts WHERE customer_id=user_id),
        (SELECT amount FROM carts WHERE customer_id=user_id));

END

MySQL工作台说

  

语法错误：意外'输出'（标识符）

我不知道出了什么问题。

编辑： 我发现了另一个关于stackoverflow的问题，其中一个类似的问题是通过使用表变量解决的，但我似乎无法声明一个表变量。 Wordbench说

  

此时TABLE不是有效输入。

这是我尝试`DECLARE MyTableVar TABLE（IdentityColumn BIGINT）;
