仅当满足两个条件时才从 SQL 查询中排除结果

Question

我有两个 table，一个存储日期范围从今天 (2021-04-22) 到今天+5，第二个存储日期范围是交货和产品。我需要 return delivery_id dates table 范围内的所有 "CUSTOM" 产品只有如果 deliveries.end_date 等于今天（因此应包括 A01，但应排除 A02）。目前它排除了一切 "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 select 我有：

    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

Answer 1

I need to return all delivery_id's which are in the range of dates table excluding "CUSTOM" products only if the deliveries.end_date is equal to today (so A01 should be included, but A02 should be excluded).

我不确定条件的第一部分是什么意思。但是您可以使用以下逻辑处理其余部分：

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.
