如何使用

Question

我想和表Salevolume一起加入表Saleperson。联接的逻辑是：

• 表Saleperson有关键：itemfrom和itemto，表Salevolume有Key：Item。当Salevolume的关键“项目”在销售人员的关键“itemfrom”和“itemto”之间时，我将由销售人员制作salevolume，group of sume

• 密钥“accountfrom”和“accountto”和“item”最后有一些时间字符

你能帮帮我吗？

由于

CREATE TABLE [dbo].[Saleperson](
[Saleperson] [nvarchar](3) NULL,
[itemfrom] [nvarchar](4) NULL,
[itemto] [nvarchar](4) NULL
)
insert into [dbo].[Saleperson]
values
('A','111H','112H'),
('B','122G','125G'),
('C','134F','137F'),
('D','117','119'),

CREATE TABLE [dbo].[Salevolume](
[Item] [nvarchar](6) NULL,
[Salevolume] [int] NULL
)

insert into [dbo].[Salevolume]
values
('112H',30),
('113H',40),
('122G',30),
('134F',50),
('118',100)

Answer 1

您需要先检查项目的最后一个字符是否为字母。如果是字母表，则检查项目的数值和字母值是否介于itemfrom和itemto的数值和字母值之间，如下所示：

select p.Saleperson,sum(v.Salevolume)
from Saleperson p
inner join Salevolume v 
    on v.Item between p.itemfrom and p.itemto
    OR  (
        RIGHT(v.Item,1)  between 'A' and 'Z' 
        and RIGHT(v.Item,1) between RIGHT(p.itemfrom,1) AND RIGHT(p.itemto,1)
        and REPLACE(v.item,RIGHT(v.Item,1),'') between REPLACE(p.itemfrom,RIGHT(p.itemfrom,1),'') and REPLACE(p.itemto,RIGHT(p.itemto,1),'')
    )
group by p.Saleperson;
