如何根据某些列值对行进行分组

【问题标题】：How to Group Rows based on some column values如何根据某些列值对行进行分组
【发布时间】：2024-04-28 19:30:01
【问题描述】：

我在表格中有如下数据。这只是一个只有1个AdmissionNo的样本数据，真实数据可能有数百个有自己的集合。所以我想根据 AdmissionNo 和 WardCode 对行进行分组，这意味着 WardCode 为“KINT”的前 13 行的 grpValue 应该为 1，接下来的两行为 2，然后是 1，依此类推。 

CREATE TABLE [dbo].[tbl_H](
    [AdmissionNo] [nvarchar](50) NULL,
    [WardCode] [nvarchar](255) NULL,
    [AdmissionDateTime] [datetime] NULL,
    [DischargeDateTime] [datetime] NULL,
    [date] [datetime] NULL
) ON [PRIMARY]

这是表格的外观：

但问题是，对于相同的 AdmissinoNo，WardCode 在后面的行中再次重复。那么如何将这些行作为不同的 GroupValue，因为当我尝试对它们进行分组时，即使它们之间存在任何其他 WardCode，它们也会组合在一起。可以根据 AdmissionDateTime 然后 DischargeDateTime 对行进行排序。 首先我通过“ROW_NUMBER()OVER(ORDER BY AdmissionNo,AdmissionDateTime,DischargeDateTime) as rownum”在列表中添加行号，然后进行以下查询：

;WITH cte as (
SELECT *,
       ROW_NUMBER() OVER (PARTITION BY AdmissionNo,WardCode ORDER BY rownum) as rn,
       rownum - ROW_NUMBER() OVER (PARTITION BY AdmissionNo,WardCode ORDER BY rownum) as grp
FROM tbl_h
)    
SELECT *, DENSE_RANK() OVER (ORDER BY grp) as new_Grp
FROM cte

但这也将所有具有相同名称的病房代码分组，即使它们之间有任何其他病房代码。

  • 我认为您的查询工作正常。加order by rownum即可查看

感谢 Ajay Gupta，我通过以下查询解决了这个问题：

;WITH cte as (
SELECT *,
   ROW_NUMBER() OVER (PARTITION BY AdmissionNo,WardCode ORDER BY rownum) as rn,
   rownum - ROW_NUMBER() OVER (PARTITION BY AdmissionNo,WardCode ORDER BY rownum) as 
grp
FROM tbl_h
)    
SELECT *, DENSE_RANK() OVER (ORDER BY grp) as new_Grp
FROM cte
ORDER BY rownum

    【解决方案2】：

    我想这就是你想要的。

    SELECT * 
FROM TABLE1 
GROUP BY AdmissinoNo,WardCode
ORDER BY AdmissinoNo,WardCode

    首先按 AdmissinoNo 和 WardCode 分组 然后按 AdmissinoNo 和 WardCode 排序

    【讨论】：

    • 感谢您的回复，但是如果您查看图像，它将14,15和17,18等组合在一起，这就是我不想要的，因为第16行有不同的wardcode。所以第 14 行和第 15 行应该有不同的 groupvalue 和 17,18 等行应该有不同的 groupvalue。
