Question

使用tsql，我试图在30天的窗口内查找成员是否有来自三个独立存储桶中的每一个的服务。水桶不一定具有独特的价值。在我的例子中，成员1在窗口中没有所有三个日期，而成员2则没有。

create table #dates (
    member tinyint,
    bucket tinyint,
    dt date
);

insert into #dates (member,bucket,dt)
    values (1,1,'20170101'),
           (1,2,'20161225'),
           (1,2,'20170204'),
           (1,3,'20170129'),
           (2,1,'20170101'),
           (2,2,'20170102'),
           (2,3,'20161231');

INITIAL QUERY

select *
from #dates d1 join
     #dates d2
     on d2.member=d1.member and d2.bucket=2 and
        d2.dt between DATEADD(DAY,-30,d1.dt) and DATEADD(day,30,d1.dt)
where d1.bucket=1

Answer 1

如果你想要成员，那么这是一种方法：

select distinct d.member
from #dates d 
where exists (select 1
              from #dates d1
              where d1.member = d.member and d1.bucket = 1 and
                    d1.dt between DATEADD(DAY, -30, d.dt) and DATEADD(day, 30, d.dt)
             ) and
      exists (select 1
              from #dates d2
              where d2.member = d.member and d2.bucket = 2 and
                    d2.dt between DATEADD(DAY, -30, d.dt) and DATEADD(day, 30, d.dt)
             ) and
      exists (select 1
              from #dates d3
              where d3.member = d.member and d3.bucket = 3 and
                    d3.dt between DATEADD(DAY, -30, d.dt) and DATEADD(day, 30, d.dt)
             ) ;
