Question

我在下表中有一个数据，如下所示。这只是一个样本数据，只有1个准入编号，实际数据可能有数百个具有自己的集合。因此，我想基于AdmissionNo和WardCode对行进行分组，这意味着WardCode为'KINT'的前13行应将grpValue设置为1，然后将下两行设置为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：

但是问题在于，对于相同的AdmissinoNo，WardCode在以后的行中再次重复。因此，如何将这些行指定为不同的GroupValue，因为当我尝试对它们进行分组时，即使它们之间还存在其他WardCode，它们也会一起分组。可以基于AdmissionDateTime然后DischargeDateTime对行进行排序。首先，我在列表中通过“ ROW_NUMBER（）OVER（ORDER BY AdmissionNo，AdmissionDateTime，DischargeDateTime）作为rownum”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

但是这也将所有同名的病区代码分组，即使它们之间还有其他病区代码。

Answer 1

由于使用了Ajay Gupta，我通过以下查询解决了该问题：

;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

Answer 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对它进行分组然后按AdmissinoNo和WardCode对其进行排序

如何根据某些列值对行进行分组
