Question

MySQL在表中插入行的功能。

CREATE FUNCTION create_business(
    phone_number TEXT,
    open_time TIME,
    close_time TIME,
    est_date DATE,
    bus_desc VARCHAR(500),
    bus_name VARCHAR(30),
    off_phones VARCHAR(100),
    off_email VARCHAR(100)
) RETURNS INT(6)
BEGIN
    declare bus_id INT;   <===
    INSERT INTO business
    (
        Name,OpenTime,CloseTime,EstDate,Description,OfficialPhone,OfficialEmail
    )
     VALUES
    (
        bus_name,open_time,close_time,est_date,bus_desc,off_phones,off_email
    );     <===
    SET bus_id = SELECT LAST_INSERT_ID();
    RETURN bus_id;  
END $$
DELIMITER ;

我找不到任何错误，并且日志也没有提供太多有关上述内容的信息。

您的功能似乎有几个问题，

您尚未宣布开始DELIMITER
SET bus_id = SELECT LAST_INSERT_ID()应该更改为`SET bus_id = LAST_INSERT_ID（）;

应该是下面的样子，

DELIMITER $$

CREATE FUNCTION create_business(
    phone_number TEXT,
    open_time TIME,
    close_time TIME,
    est_date DATE,
    bus_desc VARCHAR(500),
    bus_name VARCHAR(30),
    off_phones VARCHAR(100),
    off_email VARCHAR(100)
) RETURNS INT(6)
BEGIN

    declare bus_id varchar(2);   
    INSERT INTO business
    (
        Name,OpenTime,CloseTime,EstDate,Description,OfficialPhone,OfficialEmail
    )
     VALUES
    (
        bus_name,open_time,close_time,est_date,bus_desc,off_phones,off_email
    );    
    SET bus_id = LAST_INSERT_ID() ;
    RETURN bus_id;  
END $$
DELIMITER ;

MySQL插入使用功能不起作用
