我有两个表,一个存储日期范围从今天(2021-04-22)到今天+5,第二个存储交货和产品。如果delivery_id
等于今天,我需要返回dates
表范围内的所有"CUSTOM"
,不包括deliveries.end_date
产品仅 (因此应包括 A01
,但应排除 A02
)。目前它排除了所有 "CUSTOM"
。
输出应包括以下列:
datess | delivery_id | product
表格:
CREATE TABLE dates
(
datess DATETIME
);
INSERT INTO dates(datess)
VALUES
('2021-04-22 00:00:00.000'),
('2021-04-23 00:00:00.000'),
('2021-04-24 00:00:00.000'),
('2021-04-25 00:00:00.000'),
('2021-04-26 00:00:00.000'),
('2021-04-27 00:00:00.000')
CREATE TABLE deliveries
(
delivery_id VARCHAR(20),
product VARCHAR(10),
start_date DATETIME,
end_date DATETIME,
);
INSERT INTO deliveries(delivery_id, product, start_date, end_date)
VALUES
('A01', 'CUSTOM', '2021-04-22', '2021-04-23'),
('A02', 'CUSTOM', '2021-04-21', '2021-04-22'),
('A03', 'NORMAL', '2021-04-01', '2021-04-30'),
('A04', 'NORMAL', '2021-04-22', '2021-04-24'),
('A05', 'NORMAL', '2021-04-19', '2021-04-22'),
('A06', 'NORMAL', '2021-04-20', '2021-04-20')
这是我的选择:
declare @TodaysDate datetime = CONVERT(DATETIME, CONVERT(DATE, CURRENT_TIMESTAMP)) + '00:00:00.000'
declare @EndDate datetime = dateadd(day,5,@TodaysDate)
declare @TomorrowsDate datetime = dateadd(day,1,@TodaysDate)
select dt.datess, de.delivery_id, de.product from dates dt left join deliveries de
on dt.datess between de.start_date and de.end_date
and (de.end_date <> @TodaysDate AND de.product NOT LIKE '%CUSTOM%')
order by delivery_id
答案 0 :(得分:0)
只有在 delivery.end_date 等于今天时,我才需要返回日期表范围内的所有 delivery_id,不包括“CUSTOM”产品(因此应包括 A01,但应排除 A02)。
我不确定条件的第一部分是什么意思。但是你可以使用这个逻辑处理剩下的事情:
select d.*
from deliveries d
where not (d.product = 'CUSTOM' and d.end_date = (select min(da.datess) from dates da));
如果我理解第一个,你可以使用:
select d.*
from deliveries d
where not (d.product = 'CUSTOM' and d.end_date = (select min(da.datess) from dates da)) or
(d.product <> 'CUSTOM' and
d.start_date in (select da.datess from dates da) and
d.end_date in (select da.datess from dates da)
);
Here 是一个 db<>fiddle。
