如何根据某些列值对行进行分组
How to Group Rows based on some column values
我在 table 中有一个数据如下。这只是一个只有 1 个 AdmissionNo 的示例数据，真实数据可能有数百个 AdmissionNo。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，然后接下来的两行为 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 table 的样子：
但问题是 WardCode 在后面的行中再次重复相同的 AdmissinoNo。那么我如何才能将这些行作为不同的 GroupValue，因为当我尝试对它们进行分组时，即使它们之间有任何其他 WardCode，它们也会组合在一起。这些行可以根据 AdmissionDateTime 然后 DischargeDateTime 进行排序。
首先，我通过 "ROW_NUMBER()OVER(ORDER BY AdmissionNo,AdmissionDateTime,DischargeDateTime) as rownum" 在列表中添加了 rownumber，然后进行了查询：
;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
我用以下查询解决了这个问题，感谢 Ajay Gupta：
;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
我在 table 中有一个数据如下。这只是一个只有 1 个 AdmissionNo 的示例数据，真实数据可能有数百个 AdmissionNo。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，然后接下来的两行为 2，然后是 1，依此类推。

这是 table 的样子：
但问题是 WardCode 在后面的行中再次重复相同的 AdmissinoNo。那么我如何才能将这些行作为不同的 GroupValue，因为当我尝试对它们进行分组时，即使它们之间有任何其他 WardCode，它们也会组合在一起。这些行可以根据 AdmissionDateTime 然后 DischargeDateTime 进行排序。 首先，我通过 "ROW_NUMBER()OVER(ORDER BY AdmissionNo,AdmissionDateTime,DischargeDateTime) as rownum" 在列表中添加了 rownumber，然后进行了查询：
;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
排序我用以下查询解决了这个问题，感谢 Ajay Gupta：
;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
