Question

I have a problem to get to SQL queries into one, the problem is that I want FirstName, LastName twice. First the names from tblUploadedImages and then the names from tblImageParticipants

ALTER PROCEDURE GetFeaturedImages
AS
BEGIN
   SELECT 
       tblUser.FirstName AS FirstNameUploader, 
       tblUser.LastName AS LastNameUploader, 
       tblUser.UserID AS UserIDUploader 
   FROM 
       tblUploadedImages 
   INNER JOIN 
       tblUser ON tblUploadedImages.UserID = tblUser.UserID

   SELECT        
        tblUploadedImages.ImgUrl, 
        tblUploadedImages.ImgUrlOriginal, 
        tblUploadedImages.Description, 
        tblUploadedImages.ImageID, 
        tblUser.FirstName, 
        tblUser.LastName, 
        tblUploadedImages.UserID AS Uploader, 
        tblImageParticipants.UserID AS Participants
   FROM            
        tblImageParticipants  
   INNER JOIN
        tblUploadedImages ON tblImageParticipants.ImageID = tblUploadedImages.ImageID
   INNER JOIN
        tblUser ON tblImageParticipants.UserID = tblUser.UserID
   ORDER BY 
        tblUploadedImages.Added
END

I get the right results its just that I want it in one SQL query. How can I do that?

Answer 1

I think you are looking for a UNION ALL. A UNION removes the duplicates. What I think you want is not to remove the duplicates.

SELECT 
   tblUser.FirstName AS FirstNameUploader, 
   tblUser.LastName AS LastNameUploader, 
   tblUser.UserID AS UserIDUploader 
FROM 
   tblUploadedImages 
INNER JOIN 
   tblUser ON tblUploadedImages.UserID = tblUser.UserID

UNION ALL

SELECT        
    tblUser.FirstName, 
    tblUser.LastName, 
    tblUploadedImages.UserID AS Uploader
FROM            
    tblImageParticipants  
INNER JOIN
    tblUploadedImages ON tblImageParticipants.ImageID = tblUploadedImages.ImageID
INNER JOIN
    tblUser ON tblImageParticipants.UserID = tblUser.UserID
ORDER BY 
    tblUploadedImages.Added

It might also be a god idé to have something so you know which is which. You can add an additional column for that like this:

SELECT 
   tblUser.FirstName AS FirstNameUploader, 
   tblUser.LastName AS LastNameUploader, 
   tblUser.UserID AS UserIDUploader,
   'UploadedImages' AS Type
FROM 
   tblUploadedImages 
INNER JOIN 
   tblUser ON tblUploadedImages.UserID = tblUser.UserID

UNION ALL

SELECT        
    tblUser.FirstName, 
    tblUser.LastName, 
    tblUploadedImages.UserID AS Uploader,
    'ImageParticipants' AS Type
FROM            
    tblImageParticipants  
INNER JOIN
    tblUploadedImages ON tblImageParticipants.ImageID = tblUploadedImages.ImageID
INNER JOIN
    tblUser ON tblImageParticipants.UserID = tblUser.UserID
ORDER BY 
    tblUploadedImages.Added

I hope this helps
