Simplify SQL Server Abfrage

Question

Ich versuche, den Professor Rang, das Gehalt für diesen Rang basierend auf Abteilungsnummer und das Gesamtgehalt für alle Menschen dieses Ranges bezahlt zu zeigen. Ich versuche, die Ausgabe so zu formatieren, dass jede Spalte eine Abteilungsnummer ist. Das ist, was ich bisher herausgefunden habe.

SELECT 

ProfRank.ProfRankName, 



'$' + CAST(CAST((COALESCE(Dept1.DeptSum, 0)) AS money) as varchar) as CSET,

FROM 

    (SELECT ProfRank.ProfRankID, SUM(faculty.Salary) as DeptSum 

    FROM faculty 
    INNER JOIN dept ON faculty.DeptID = dept.DeptID 
    INNER JOIN ProfRank ON faculty.Salary BETWEEN ProfRank.Minimumm AND ProfRank.Maximum 
    WHERE dept.DeptID = 1 
    GROUP BY ProfRankID 
    ) as Dept1 

    FULL OUTER JOIN 
      (SELECT ProfRank.ProfRankID, SUM(faculty.Salary) as DeptSum

      WHERE dept.DeptID = 2 
      GROUP BY ProfRankID 
      ) as Dept2 

        ON Dept1.ProfRankID = Dept2.ProfRankID 

    FULL OUTER JOIN 

      (SELECT ProfRank.ProfRankID, SUM(faculty.Salary) as DeptSum 
      FROM faculty 
      INNER JOIN dept ON faculty.DeptID = dept.DeptID 
      INNER JOIN ProfRank ON faculty.Salary BETWEEN ProfRank.Minimumm AND ProfRank.Maximum 
      WHERE dept.DeptID = 3 
      GROUP BY ProfRankID 
      ) as Dept3 
        ON Dept2.ProfRankID = Dept3.ProfRankID 

    FULL OUTER JOIN 
      (SELECT ProfRank.ProfRankID, SUM(faculty.Salary) as DeptSum

      OR ProfRank.ProfRankID = Dept3.ProfRankID 
      OR ProfRank.ProfRankID = Dept4.ProfRankID 

    ORDER BY ProfRank.ProfRankID 

Die Ausgabe lautet:

Gibt es eine Möglichkeit, diesen Code zu kondensieren, und es kürzer und effizienter machen ??

Um die Abfrage dynamischer zu gestalten, zu erstellen, falls Sie eine andere Abteilung in der Zukunft hinzufügen, sollten Sie das Schwenken auf die Client-Seite verschieben:

SELECT r.ProfRankName, 
    d.DeptID, 
    SUM(f.Salary) as Total 
FROM faculty f 
INNER JOIN dept d ON f.DeptID = d.DeptID 
INNER JOIN ProfRank r ON f.Salary BETWEEN r.Minimumm AND r.Maximum 
GROUP BY d.DeptID, r.ProfRankID, r.ProfRankName
