sql select from table with date range condition - mysql

Question

I have this table
CREATE TABLE `tarif` (
`tarif_id` int(11) NOT NULL AUTO_INCREMENT,
`start_tarif` date NOT NULL,
`end_tarif` date NOT NULL,
`day_tarif` varchar(50) NOT NULL,
PRIMARY KEY (`tarif_id`)
);
INSERT INTO `tarif` VALUES (1, '2019-02-01', '2019-02-10', '10'),
(2, '2019-02-11', '2019-02-20', '20'),
(3, '2019-02-21', '2019-02-28', '10'),
(4, '2019-03-01', '2019-02-10', '15');
How can I get day_tarif between 2019-02-05 and 2019-02-15 and calculate the sum = day_tarif * number of date betwwen 2019-02-05 and 2019-02-15

Answer 1

You can use the following solution using DATEDIFF:
SELECT SUM((DATEDIFF(LEAST(`end_tarif`, '2019-02-15'), GREATEST(`start_tarif`, '2019-02-05')) + 1) * `day_tarif`) AS sumCustom
FROM `tarif`
WHERE `end_tarif` >= '2019-02-05' AND `start_tarif` <= '2019-02-15'

You can use the following solution using SUM and COUNT:
SELECT SUM(`day_tarif`) * COUNT(`tarif_id`)
FROM `tarif`
WHERE `end_tarif` >= '2019-02-05' AND `start_tarif` <= '2019-02-15'

Answer 2

select SUM(day_tarif) * COUNT(tarif_id)
from tarif
where end_date >= '2019-02-05' AND start_date <= '2019-02-15'

Answer 3

You can try following code:
WITH cte AS(
SELECT *
FROM tablename
WHERE end_tarif >= '2019-02-05' AND start_tarif <= '2019-02-15'
)
SELECT day_tarif, day_tarif * COUNT(tarif_id) AS 'SUM'
FROM cte
group by day_tarif;

I think this might be what you are after...
Declare #tarif as table (
tarif_id int NOT NULL ,
start_tarif date NOT NULL,
end_tarif date NOT NULL,
day_tarif varchar(50) NOT NULL
);
INSERT INTO #tarif VALUES (1, '2019-02-01', '2019-02-10', '10'),
(2, '2019-02-11', '2019-02-20', '20'),
(3, '2019-02-21', '2019-02-28', '10'),
(4, '2019-03-01', '2019-02-10', '15');
-- Declare parameters
Declare #paramstart date, #paramend date
Set #paramstart='2019-02-05'
Set #paramend='2019-02-15'
-- Set up loop
Declare #mincount int, #maxcount int, #myval int, #curstart date, #curend date,#curtarif int, #mytarif int
Set #mincount=(Select MIN(tarif_id) from #tarif where end_tarif >= '2019-02-05' AND start_tarif <= '2019-02-15')
Set #maxcount=(Select Max(tarif_id) from #tarif where end_tarif >= '2019-02-05' AND start_tarif <= '2019-02-15')
Set #mytarif=0
-- Do loop
WHile #mincount<=#maxcount
BEGIN
Set #curstart=(Select start_tarif from #tarif where tarif_id=#mincount)
Set #curend=(Select end_tarif from #tarif where tarif_id=#mincount)
Set #curtarif=(Select cast(day_tarif as int) from #tarif where tarif_id=#mincount)
IF #paramstart between #curstart and #curend
BEGIN
Set #mytarif=#mytarif+((DATEDIFF(day,#paramstart,#curend)+1) * #curtarif)
END
IF #paramend between #curstart and #curend
BEGIN
Set #mytarif=#mytarif+((DATEDIFF(day,#curstart,#paramend)+1) * #curtarif)
END
IF #paramstart not between #curstart and #curend and #paramend not between #curstart and #curend
BEGIN
Set #mytarif=#mytarif+((DATEDIFF(day,#curstart,#curend)+1) * #curtarif)
END
Set #mincount=#mincount+1
END
Select #mytarif as tarif

Answer 5

Try this!
select day_tarif , sum(day_tarif * count (*)) as sum
where start_tarif between '2019/02/05' and '2019/02/15' and end_tarif between '2019/02/05' and '2019/02/15'
group by day_tarif;
