Comment ajouter une colonne supplémentaire à l'exécution dans SQL Server

Question

Ma requête est

SELECT 
    RemainingQty, CompletedQty 
FROM 
    tblJobStatus AS JT 
LEFT OUTER JOIN 
    TBLJOBWORKS AS TJ ON JobWorksId = TaskId 
LEFT OUTER JOIN 
    tblTotalJob AS T ON T.Id = JobID  
WHERE 
    JT.ProductID = '28' 
    AND ItemId = '15' 
ORDER BY 
    JobSequence ASC 

Lors de l'exécution de la requête que je reçois ce résultat

Maintenant, je veux ajouter une colonne supplémentaire avec ceci à l'exécution qui contiendra le statut. Si le RemainingQty est 0 et que CompletedQty est supérieur à 0, la colonne d'état contiendra l'autre instruction en attente.

comme suit image

Est-il possible sans une boucle?

Answer 1

Bien sûr, pas de problème - c'est une expression CASE très simple:

SELECT 
    RemainingQty, CompletedQty, 
    Status = CASE 
       WHEN RemainingQy = 0 AND CompletedQty > 0 
       THEN 'Complete' 
       ELSE 'Pending' 
      END 
FROM 
    tblJobStatus AS JT 
LEFT OUTER JOIN 
    TBLJOBWORKS AS TJ ON JobWorksId = TaskId 
LEFT OUTER JOIN 
    tblTotalJob AS T ON T.Id = JobID  
WHERE 
    JT.ProductID = '28' 
    AND ItemId = '15' 
ORDER BY 
    JobSequence ASC 

Answer 2

select 
    ..., 
    case 
     when RemainingQty = 0 and CompletedQty > 0 then 'Complete' 
     else 'Pending' 
    end as Status 
from ...
