Question

以下是示例存储过程：

在这里，我希望将模式传递为（1,2，（1,2））和user_types为（1,2或0，两者为（1,2））

我该如何写这种情况

    DELIMITER ;

    CREATE PROCEDURE `Statistics`
    (
       IN Start_Date DATE,
       IN END_Date DATE,
       IN Modes  int,
       IN User_Type INT
    )
    BEGIN

    -- User_Type = (0 0r 1 or 2)
    -- modes=(1 or 2 or (1,2))


    IF (User_Type=0)
    THEN
            select * from table 
            where modes in (1 or 2 or (1,2)) AND Dates BETWEEN Start_Date AND End_Date
       GROUP BY  Dates;
    ELSE
    IF(User_Type=1)
    THEN
              select * from table 
            where modes in (1 or 2 or (1,2)) AND Dates BETWEEN Start_Date AND End_Date

    ELSE
    IF (User_Type=2)
    THEN
                select * from table 
            where modes in (1 or 2 or (1,2)) AND Dates BETWEEN Start_Date AND End_Date

    END IF;

     END IF;
    END IF;
    END$$

    DELIMITER ;
