  Hi All, need help with an SQL query.

  We have an existing table that's already formatted this way, and I am having trouble extracting the data in single record.

  Current Output:

  

  EXPECTED OUTPUT: The EndDate and EndTime I want it displayed in the same row where BName like '% Start'

  

  I tried to do this through cursor by updating the EndDate and EndTime, but that is not working. Below is an test query I was trying it against.

     DECLARE @tblData TABLE
     (BName varchar(50),
      StartDate varchar(10),
      StartTime varchar(10),
      EndDate varchar(10),
      EndTime varchar(10))
  
     INSERT INTO @tblData (BName, StartDate, StartTime) VALUES ('STAT Start','02/20/2025','00:34:02')
     INSERT INTO @tblData (BName, StartDate, StartTime) VALUES ('STAT End','02/20/2025','00:40:36')
     INSERT INTO @tblData (BName, StartDate, StartTime) VALUES ('CDS Start','02/20/2025','00:40:38')
     INSERT INTO @tblData (BName, StartDate, StartTime) VALUES ('CDS End','02/20/2025','00:47:26')
     INSERT INTO @tblData (BName, StartDate, StartTime) VALUES ('LED Start','02/20/2025','00:40:42')
     INSERT INTO @tblData (BName, StartDate, StartTime) VALUES ('LED End','02/20/2025','00:54:28')

   

  Thanks!

  SELECT
      LEFT(Bname, CHARINDEX(' ', BName) - 1) AS BName,
      MAX(CASE WHEN BName LIKE '% Start%' THEN StartDate ELSE '' END) AS StartDate,
      MAX(CASE WHEN BName LIKE '% Start%' THEN StartTime ELSE '' END) AS StartTime,
      MAX(CASE WHEN BName LIKE '% End%' THEN StartDate ELSE '' END) AS EndDate,
      MAX(CASE WHEN BName LIKE '% End%' THEN StartTime ELSE '' END) AS EndTime
  FROM @tblData 
  GROUP BY LEFT(Bname, CHARINDEX(' ', Bname) - 1)
  ORDER BY 1, 2

  with stub_cte as (
      select BName, StartDate, StartTime, 
             lag(StartDate) over (partition by v.stub order by v.dt desc) EndDate,
