mysql - #1064 - 你的 SQL 语法有错误；检查与您的 MariaDB 服务器版本相对应的手册以获取正确的语法

Question

请帮帮我，我想创建程序，但我发现了这样的错误

CREATE PROCEDURE studentAddOrEdit(
    IN _id INT,
    IN _firstname VARCHAR(191),
    IN _lastname VARCHAR(191)
)
BEGIN
IF _id = 0 THEN 
    INSERT INTO students(firstname, lastname) VALUES(_firstname,_lastname);
    SET  _id = LAST_INSERT_ID(); 
ELSE
    UPDATE
        students
    SET
        firstname = _firstname, lastname = _lastname
    WHERE
        id = _id;
END IF;
SELECT
    id AS _id
END

现在它说

#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 '' at line 7

Answer 1

当我添加几个分号时，您的代码就可以工作。 Here就是一个例子。

您可能还应该有一个 DELIMITER 语句，尽管这在 db<>fiddle 中似乎不起作用。
