TSQL语法在两列组上递增

Question

我需要语法帮助才能根据2列的分组来增加列。

以下显示了所需的输出，其中我想显示按DateTime

分割的每个ID的增量

我尝试了以下内容但没有成功

SELECT hl.ts_DateTime,  
       hl.Tagname as [ID],  
       hl.TagValue as [Value],
       DENSE_RANK() OVER (ORDER BY hl.Tagname, ts_datetime) AS RowFilter
FROM   Table1 hl 
ORDER  BY hl.Tagname,  hl.ts_DateTime


SELECT hl.ts_DateTime,  
       hl.Tagname as [ID],  
       hl.TagValue as [Value],
       ROW_NUMBER() OVER (PARTITION BY ts_DateTime, Tagname  ORDER BY ts_DateTime ASC)  AS RowFilter
FROM   Table1 hl 
ORDER  BY hl.Tagname,  hl.ts_DateTime
