本文介绍了根据日期条件合并不同的行的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我在 SO 上找到了这篇文章，但它用 bigquery 解决了，我用 SQL 查询尝试过，但我在使用太多变量和循环时遇到了问题.尽管结果如此，但此查询可能不是最佳的.希望大家帮帮我

我有一个包含 playid、userid、创建和停止的表.我想通过保留最早创建的行并在最早创建的 120 分钟内停止最新行来合并某些行.

预期结果:

 解决方案 
这里我将尝试逐个解释查询(恐怕我可能不是一个很好的解释者):
架构和插入语句:
 创建表数据(playid int, userid varchar(10), created datetime,stopped datetime)；插入数据值(1,'a01','01/30/2021 02:29:58.560','01/30/2021 02:40:56.558');插入数据值(2,'a01','01/30/2021 02:41:24.023','01/30/2021 02:55:24.113');插入数据值(3,'a01','01/30/2021 02:57:30.179','01/30/2021 03:11:14.867');插入数据值(4,'a01','01/30/2021 03:11:41.098','01/30/2021 03:22:50.156');插入数据值(5,'a01','01/30/2021 03:23:20.545','01/30/2021 03:36:37.027');插入数据值(6,'a01','01/30/2021 03:46:10.238','01/30/2021 03:59:17.526');插入数据值(7,'a01','01/30/2021 03:59:57.020','01/30/2021 04:16:25.948');插入数据值(8,'a01','01/30/2021 04:26:28.969','01/30/2021 04:30:11.863');插入数据值(9,'a01','01/30/2021 04:30:14.438','01/30/2021 04:41:42.232');插入数据值(10,'a01','01/30/2021 04:43:17.670','01/30/2021 04:45:10.443');插入数据值(11,'a01','01/30/2021 04:45:14.503','01/30/2021 04:47:07.082');插入数据值(12,'a01','01/30/2021 04:47:10.335',​​'01/30/2021 04:49:30.960');插入数据值(13,'a01','01/30/2021 04:49:34.146','01/30/2021 04:50:54.460');插入数据值(14,'a01','01/30/2021 04:50:57.948','01/30/2021 05:11:01.246');插入数据值(15,'a01','01/30/2021 05:39:29.387','01/30/2021 05:41:39.509');插入数据值(16,'a01','01/30/2021 05:41:44.525','01/30/2021 05:43:38.231');插入数据值(17,'a01','01/30/2021 05:43:40.786','01/30/2021 05:54:40.711');插入数据值(18,'a01','01/30/2021 05:55:10.852','01/30/2021 05:58:24.262');插入数据值(19,'a01','01/30/2021 05:58:29.438','01/30/2021 06:00:50.871');插入数据值(20,'a01','01/30/2021 06:00:54.169','01/30/2021 06:12:37.210');插入数据值(21,'a01','01/30/2021 14:41:01.530','01/30/2021 14:53:01.349');插入数据值(22,'a01','01/30/2021 14:53:48.053','01/30/2021 15:05:09.533');插入数据值(23,'a01','01/31/2021 15:11:08.547','01/31/2021 15:11:37.565');插入数据值(24,'a01','01/31/2021 15:11:40.248','01/31/2021 15:13:40.218');插入数据值(25,'a01','01/31/2021 15:13:59.373','01/31/2021 15:31:54.100');插入数据值(26,'a01','01/31/2021 15:32:23.204','01/31/2021 15:46:33.994');插入数据值(27,'a01','01/31/2021 16:55:19.141','01/31/2021 17:03:43.464');
查询的第一部分:
 从数据d中选择d.playid,d.userid,d.created,d.stopped,dt.minstopped外申请(从数据 dt 中选择 max(stopped) minstopped其中 d.playid
在上面的查询中，我添加了一个名为 minstopped 的新列，它将计算最大停止日期时间.背后的逻辑是，当我们计算第一行的 minstopped 时，我们将从停止日期不大于第一行的创建日期加上 120 分钟的所有行计算 max(sopped).
输出:
<头>
playiduserid创建停止minstopped

第二部分将停止日期与上一组第一行的创建日期相距超过 120 分钟的所有行组成一个组.所以我们现在有一组行，用于创建日期和停止日期之间的每 120 分钟间隔.

I found this post on SO, but it solved with bigquery, I tried it with SQL query and I have problems using too many variables and loops. Despite the results, this query may not be optimal. Hope everyone help me

I have a table with playid, userid, created, and stopped. I want to merge certain rows by keeping the earliest created and the latest stopped within 120 minutes from the earliest created.

Desired Result:

playid userid created stopped

First Part of Query:

     select d.playid,d.userid,d.created,d.stopped,dt.minstopped from data d
      outer apply (
      select max(stopped) minstopped from data dt 
      where  d.playid<dt.playid and datediff(minute,d.created,dt.stopped)<=120
      and d.userid=dt.userid)dt

In above query I have added a new column named minstopped which will calculate the maximum stopped date time. The logic behind is when we are calculating minstopped for first row we will calculate max(sopped) from all the rows having stopped date no greater than created date from first row plus 120 minutes.

Output:

playid userid created stopped minstopped

Second part to make a group with all the rows where stopped date is more than 120 minutes from the created date of first row from previous group. So we now have a group of rows for every 120 minutes gap between created date and stopped date.

 with cte as
    (
      select d.playid,d.userid,d.created,d.stopped,dt.minstopped from data d
      outer apply (
      select max(stopped) minstopped from data dt 
      where  d.playid<dt.playid and datediff(minute,d.created,dt.stopped)<=120
      and d.userid=dt.userid)dt 
    ),

    (
    select top 1 *, 1 level from cte order by playid 
    union all
    select cte.* ,level+2 level from cte inner join cte2 on cte.stopped>cte2.minstopped
    )
    select * from cte2
    order by level, playid

Final Query: In final query we will chose first row with the minimum playid from each group. In that way we will get only rows having more than 120 mintuts gap between created date of a row and stopped date of next row.

 with cte as
   (
    select d.playid,d.userid,d.created,d.stopped,dt.minstopped from data d
    outer apply (
    select max(stopped) minstopped from data dt 
    where  d.playid<dt.playid and datediff(minute,d.created,dt.stopped)<=120
    and d.userid=dt.userid)dt 
   ),
   cte2 as 
   (
  select top 1 *, 1 level from cte order by playid 
  union all
  select cte.* ,level+2 level from cte inner join cte2 on cte.stopped>cte2.minstopped
   ),
   cte3 as 
   (
  select *,row_number()over(partition by level order by playid) rn from cte2
   )
   SELECT playid,userid,created,minstopped stopped FROM CTE3 WHERE RN=1
GO

Final output:

playid userid created stopped
