Question

也许有人可以帮助解决此问题：

CREATE FUNCTION inc_btw (prijs DECIMAL(5,2), btw DECIMAL(3,2))
    RETURNS DECIMAL(5,2)
    DETERMINISTIC
    BEGIN
        DECLARE inc_btw DECIMAL(10,2);
        inc_btw = (prijs*(btw+100))/100;
        RETURN inc_btw;
    END;

我觉得这很好，但是我收到了一个错误：

#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 '' at line 5

Answer 1

尝试摆弄你的分隔符：

delimiter $$
CREATE FUNCTION inc_btw (prijs DECIMAL(5,2), btw DECIMAL(3,2))
    RETURNS DECIMAL(5,2)
    DETERMINISTIC
    BEGIN
        DECLARE inc_btw DECIMAL(10,2);
        set inc_btw = (prijs*(btw+100))/100;
        RETURN inc_btw;
    END$$
delimiter;

Answer 2

尝试这样做（使用delimiter，但set

中缺少inc_btw = (prijs*(btw+100))/100;

DELIMITER $$
CREATE FUNCTION inc_btw (prijs DECIMAL(5,2), btw DECIMAL(3,2))
    RETURNS DECIMAL(5,2)
    DETERMINISTIC
    BEGIN
        DECLARE inc_btw DECIMAL(10,2);
        set inc_btw = (prijs*(btw+100))/100;
        RETURN inc_btw;
    END;
$$
DELIMITER ;

Answer 3

delimiter $$
CREATE FUNCTION inc_btw (prijs DECIMAL(5,2), btw DECIMAL(3,2))
    RETURNS DECIMAL(5,2)
    DETERMINISTIC
    BEGIN
        DECLARE inc_btw DECIMAL(10,2);
        set inc_btw = (prijs*(btw+100))/100;
        RETURN inc_btw;
    END$$

MySQL函数（）不起作用
