一、创建表
CREATE TABLE non_working_days (
`date` date NOT NULL
)
2023-01-25
2023-04-02
2023-04-22
2023-08-20
2023-09-29
二、函数
CREATE FUNCTION calculate_workday(start_time DATE, end_time DATE)
RETURNS INT
BEGIN
DECLARE day_diff INT;
SELECT DATEDIFF(end_date, start_date) + 1 - COUNT(non_working_days.date) into day_diff
FROM non_working_days
CROSS JOIN
(SELECT start_time AS start_date,end_time AS end_date) AS date_range
WHERE non_working_days.date BETWEEN start_date AND end_date;
RETURN day_diff;
END
三 测试
-- 测试
SELECT calculate_workday('2024-02-20 12:12:01', '2024-02-29')
