我尝试从MySQL NOW()函数获取相对日期和时间(例如2秒前,3天前,12月31日……),但我不知道该怎么做!有任何想法吗?非常感谢!

最佳答案

使用TIMESTAMPDIFF()功能。参见示例:

SELECT
    TIMESTAMPDIFF(SECOND, `stamp_column`, NOW()) as `seconds`
FROM
    `YourTable`


或使用此存储的功能:

CREATE FUNCTION `PassedSince`(`stamp` TIMESTAMP)
RETURNS VARCHAR(100)
DETERMINISTIC
BEGIN
DECLARE `result` VARCHAR(100) DEFAULT '';
DECLARE `seconds`, `minutes`, `hours`, `days` INT;

SET `seconds` = TIMESTAMPDIFF(SECOND, `stamp`, NOW());

SET `days`    = `seconds` DIV (24 * 60 * 60);
SET `seconds` = `seconds` MOD (24 * 60 * 60);

IF `days` > 0
THEN SET `result` = CONCAT(`result`, `days`, ' Days ');
END IF;

SET `hours`   = `seconds` DIV (60 * 60);
SET `seconds` = `seconds` MOD (60 * 60);

IF `hours` > 0
THEN SET `result` = CONCAT(`result`, `hours`, ' Hours ');
END IF;

SET `minutes` = `seconds` DIV 60;
SET `seconds` = `seconds` MOD 60;

IF `minutes` > 0
THEN SET `result` = CONCAT(`result`, `minutes`, ' Minutes ');
END IF;

IF `seconds` > 0
THEN SET `result` = CONCAT(`result`, `seconds`, ' Seconds ');
END IF;

RETURN TRIM(`result`);
END


查询:

SELECT
    `PassedSince`('2013-06-19 08:00') as `result`
UNION ALL
SELECT
    `PassedSince`('2013-01-01 00:00')


显示:

result
