SQL Server window function implementation issue

I have a table structure like below:

enter image description here

I have the following query to get the unique result from the table:

 WITH Dupes AS 
 (
     SELECT    
         ID, Template_ID, Address, Job_Number, Other_Info,
         Assigned_By, Assignees, Active, seen,
         ROW_NUMBER() OVER (PARTITION BY Template_ID,Job_Number ORDER BY ID) AS RowNum
     FROM 
         Schedule  
     WHERE 
         Assignees IN ('9', '16', '22')
)
SELECT 
    ID, Template_ID, Job_Number, Address, Other_Info,
    Assigned_By, Assignees, Active, seen 
FROM 
    Dupes 
WHERE 
    RowNum = 1

Output of the above query is:

enter image description here

If the Job_Number and Template_ID are same, only return one row(first row using ID). That is why I did use ROW_NUMBER() OVER(PARTITION BY Template_ID,Job_Number ORDER BY ID) AS RowNum. I am not sure how to fix this as I rarely used this function.

I need to get the output like below:

Tried the code below: enter image description here

Solution

  • seems your trying to group by Job_Number, remove Template_ID on your partition by clause

     WITH Dupes AS 
 (
      SELECT  ID,Template_ID,Address,Job_Number,Other_Info,Assigned_By,Assignees,Active,seen,
      ROW_NUMBER() OVER(PARTITION BY rtrim(ltrim(Job_Number)) ORDER BY  ID) AS RowNum
      FROM Schedule  
      WHERE Assignees IN('9','16','22')
  )
  SELECT ID,Template_ID,Job_Number,Address,Other_Info,Assigned_By,Assignees, Active,seen FROM Dupes WHERE RowNum=1
