MySQL定义方法和存储过程

mysql方法：

DELIMITER $$
CREATE DEFINER=`root`@`localhost` FUNCTION `Fir_Work_Day`(interval_day nvarchar(10)) RETURNS int(11)
BEGIN   
    /*DECLARE day_temp INTEGER;
    DECLARE month_temp INTEGER;*/
    DECLARE date_flag date;
 
select min(`date`)  into date_flag
from dim_date
where y = year(now())
and m = month(now())
and Holiday_flag in(0,2);  

if CURDATE() <= ADDDATE(date_flag, INTERVAL interval_day day) 

then return 0;  # month need -1
ELSE return 1;  # month not need change
end if;

 
END$$
DELIMITER ;
