Sql 搜索事件和紧挨着前面的事件

以下是表格的布局（仅显示相关行）：

我想提取eventid 300010的所有事件，这些事件后面紧跟着eventid 300020-关键是我的表有800个不同的id，我需要它查找相同id的前一个事件

所以我的结果是这样的：

B       2020-01-21 13:02:45.000       300010
B       2020-01-21 13:02:90.000       300020

---

非常感谢您的帮助。

您可以这样做： 对于相同的id，给我事件300010，事件300020在后面，但两者之间没有事件

     WITH CTE AS
(                          
SELECT 'A'   AS id,    '2020-01-21 13:02:00.000'  AS timestamp,     300010 AS eventno
UNION SELECT'B',       '2020-01-21 13:02:45.000',       300010
UNION SELECT'E',       '2020-01-21 13:02:50.000',       300010
UNION SELECT'B',       '2020-01-21 13:02:90.000',       300020
UNION SELECT 'M',      '2020-01-21 13:03:56.000',      300010
)



    select *
    from CTE a
    inner join CTE b
        on a.eventno = 300010 and b.eventno = 300020 and a.timestamp < b.timestamp and a.id = b.id                   
        and not exists (
            select 1
            from CTE c
            where c.timestamp > a.timestamp
            and c.timestamp < b.timestamp and c.id = b.id
        )

如果希望一行位于另一行的下方：

     WITH CTE AS
(                          
SELECT 'A'   AS id,    '2020-01-21 13:02:00.000'  AS timestamp,     300010 AS eventno
UNION SELECT'B',       '2020-01-21 13:02:45.000',       300010
UNION SELECT'E',       '2020-01-21 13:02:50.000',       300010
UNION SELECT'B',       '2020-01-21 13:02:90.000',       300020
UNION SELECT 'M',      '2020-01-21 13:03:56.000',      300010
)


select a.*
from CTE a
inner join CTE b
    on a.eventno = 300010 and b.eventno = 300020 and a.timestamp < b.timestamp and a.id = b.id                   
    and not exists (
        select 1
        from CTE c
        where c.timestamp > a.timestamp
        and c.timestamp < b.timestamp and c.id = b.id
    )

 union
 select b.*
from CTE a
inner join CTE b
    on a.eventno = 300010 and b.eventno = 300020 and a.timestamp < b.timestamp and a.id = b.id                   
    and not exists (
        select 1
        from CTE c
        where c.timestamp > a.timestamp
        and c.timestamp < b.timestamp and c.id = b.id
    )
order by id, eventno

ms sql server mgmt studioFYI SSMS不是DBMS，它只是一个客户端接口。当您说“我需要它查找相同id的前一个事件”时，我假设仅针对事件号300010和300020。这就是你的意思吗？它不会返回表中与问题中相同的任何行。更新：对不起，是的。我的错误。我不小心将

eventid

改为

id

，而不是

eventno

@Scratte，为我的答案添加了更多细节。Thx@Scrattle，将别名更改为非内部别名，否则将生成错误。更改为x，则查询为perfect@zip哦这对SQL Server来说是特别的吗？我猜，SQL说：Msg 156，级别15，状态1，第22行关键字“内部”附近的语法不正确。但是一旦换成其他的，它就可以工作了。谢谢你对它的测试：）我只有一个SQLite。像冠军一样工作……你帮了我，教了我一些东西——非常感谢。
