SQL Server 2012 Pivot Table

I need to create a query that shows the results in a pivot table.

I have a spreadsheet that is regularly updated with clients. Build state changes.

We have 8 assembly steps

  • 115 Acquired land
  • 116 Foundations
  • 117 Mounted / Wall Mounted Tile Timber Kit
  • 118 Wind and Water Tight
  • 119 1st patch and plaster
  • 120 Final Fit Out
  • 121 Completed
  • 122 Extinguished

Here is my request

SELECT 
    s.ProjectStage, su.DateStageChanged, p.FK_ID As ID,
    s.LongDesc AS BuildType, su.FK_StageID  
FROM 
    [dbo].[tbl_StageUpdates] AS su
LEFT JOIN
    [dbo].[tbl_Stage] AS s ON su.FK_StageID = s.id
LEFT JOIN 
    tbl_Projects AS p ON su.FK_ProjectID = p.PK_ProjectID
WHERE 
    s.LongDesc = 'New Build'
GROUP BY 
    p.FK_ID, s.ProjectStage, su.DateStageChanged, s.LongDesc, su.FK_StageID
ORDER BY 
    su.FK_StageID ASC

ID is the client ID that I would like the request to display the following information:

Can this be done?

Any help on this would be greatly appreciated

Greetings

If you have only 8 steps, you can use CASE ... WHEN and GROUP BY to archive the expected result. I think this is more readable than using the PIVOT function. Also, it is T-SQL and will be easier to port to other DBMSs.



SELECT 
   ID, 
   BuildType,
   MAX(CASE FK_StageID WHEN 115 THEN DateStageChanged ELSE NULL END) AS [Land Purchased],
   MAX(CASE FK_StageID WHEN 116 THEN DateStageChanged ELSE NULL END) AS [Foundations],
   MAX(CASE FK_StageID WHEN 117 THEN DateStageChanged ELSE NULL END) AS [Timber Kit Erected / Wall Plate Level],
   MAX(CASE FK_StageID WHEN 118 THEN DateStageChanged ELSE NULL END) AS [Wind & Water Tight],
   MAX(CASE FK_StageID WHEN 119 THEN DateStageChanged ELSE NULL END) AS [1st Fix & Plastering],
   MAX(CASE FK_StageID WHEN 120 THEN DateStageChanged ELSE NULL END) AS [Final Fit Out],
   MAX(CASE FK_StageID WHEN 121 THEN DateStageChanged ELSE NULL END) AS [Completed],
   MAX(CASE FK_StageID WHEN 122 THEN DateStageChanged ELSE NULL END) AS [Redeemed]
FROM
   (
    -- original query  
        SELECT 
            s.ProjectStage, su.DateStageChanged, p.FK_ID As ID,
            s.LongDesc AS BuildType, su.FK_StageID  
        FROM 
            [dbo].[tbl_StageUpdates] AS su
        LEFT JOIN
            [dbo].[tbl_Stage] AS s ON su.FK_StageID = s.id
        LEFT JOIN 
            tbl_Projects AS p ON su.FK_ProjectID = p.PK_ProjectID
        WHERE 
            s.LongDesc = 'New Build'
        GROUP BY 
            p.FK_ID, s.ProjectStage, su.DateStageChanged, s.LongDesc, su.FK_StageID
    -- original query           
   )  Data 
GROUP BY 
   ID, BuildType
