此查询将显示2011年2月1日午夜的确切天数，小时数，分钟数和秒数：
SELECT
TRIM(REPLACE(CONCAT(
IF(dy=0,”,IF(dy=1,’1 day ‘,CONCAT(dy,’ days ‘))),
IF(hr=0,”,IF(hr=1,’1 hr ‘, CONCAT(hr,’ hrs ‘))),
IF(mn=0,”,IF(mn=1,’1 min ‘,CONCAT(mn,’ mins ‘))),
IF(sc=0,”,IF(sc=1,’1 sec ‘,CONCAT(sc,’ secs ‘)))),’ ‘,’ ‘))
TimeDisplay
FROM (SELECT dy,hr,mn,MOD(sec_aaaa,60) sc
FROM (SELECT dy,hr,FLOOR((sec_aaa – dy*86400 – hr*3600)/60) mn,sec_aaa sec_aaaa
FROM (SELECT dy,FLOOR((sec_aa – (dy*86400))/3600) hr,sec_aa sec_aaa
FROM (SELECT FLOOR(sec_a/86400) dy,sec_a sec_aa
FROM (SELECT (UNIX_TIMESTAMP() – UNIX_TIMESTAMP(‘2011-02-01 00:00:00’)) sec_a)
A) AA) AAA) AAAA) B;只需将’2011-02-01 00:00:00’替换为您想要的任何日期时间值或表列名称即可。

我写了一个你可以调用的存储函数，它将为你处理：
DELIMITER $$
DROP FUNCTION IF EXISTS `test`.`GetTimeDisplay` $$
CREATE FUNCTION `test`.`GetTimeDisplay` (GivenTimestamp TIMESTAMP)
RETURNS VARCHAR(32)
DETERMINISTIC
BEGIN
DECLARE rv VARCHAR(32);
DECLARE diff BIGINT;
SET diff = UNIX_TIMESTAMP() – UNIX_TIMESTAMP(GivenTimestamp);
SELECT
TRIM(REPLACE(CONCAT(
IF(dy=0,”,IF(dy=1,’1 day ‘,CONCAT(dy,’ days ‘))),
IF(hr=0,”,IF(hr=1,’1 hr ‘, CONCAT(hr,’ hrs ‘))),
IF(mn=0,”,IF(mn=1,’1 min ‘,CONCAT(mn,’ mins ‘))),
IF(sc=0,”,IF(sc=1,’1 sec ‘,CONCAT(sc,’ secs ‘)))),’ ‘,’ ‘))
INTO rv
FROM (SELECT dy,hr,mn,MOD(sec_aaaa,60) sc
FROM (SELECT dy,hr,FLOOR((sec_aaa – dy*86400 – hr*3600)/60) mn,sec_aaa sec_aaaa
FROM (SELECT dy,FLOOR((sec_aa – (dy*86400))/3600) hr,sec_aa sec_aaa
FROM (SELECT FLOOR(sec_a/86400) dy,sec_a sec_aa
FROM (SELECT ABS(UNIX_TIMESTAMP() – UNIX_TIMESTAMP(GivenTimestamp)) sec_a)
A) AA) AAA) AAAA) B;
IF diff = 0 THEN
SET rv = ‘0 secs’;
END IF;
IF diff < 0 THEN
SET rv = CONCAT(rv,’ From Now’);
END IF;
IF diff > 0 THEN
SET rv = CONCAT(rv,’ Ago’);
END IF;
RETURN rv;
END $$
DELIMITER ;您可以像这样重写查询：
$query = “select country, rprice as regPrice, mprice as midPrice, pprice as prePrice, saddress as streetAddress,
_id as ID, lat, lng, sname as Name, logo, admin_level_1 as state, locale as city, test.GetTimeDisplay(rdate) as regDate,
test.GetTimeDisplay(mdate) as midDate, test.GetTimeDisplay(pdate) as preDate,
format((acos(sin(radians($lat1)) * sin(radians(lat)) + cos(radians($lat1)) *
cos(radians(lat)) * cos(radians($lng1) – radians(lng))) * 6378),1) as distance from stationDetails where
(acos(sin(radians($lat1)) * sin(radians(lat)) + cos(radians($lat1)) * cos(radians(lat)) *
cos(radians($lng1) – radians(lng))) * 6378) <= $rad order by $sort asc, $type asc";您可能希望将存储的函数移动到另一个数据库。我的代码将存储的函数放在测试数据库中。
试一试 ！！！
