Mehrere verschachtelte SELECT-Anweisungen in eine PIVOT-Tabelle konvertieren

Question

Ich möchte meine Datensätze horizontal anzeigen (Zeilen zu Spalten) und habe die folgende SQL-Anweisung erstellt, die den Job erledigt, aber ich denke, sie könnte verbessert werden.

Ich habe PIVOT-Tabellen recherchiert und glaube, sie würden es viel sauberer/efficeint machen, ich kann den PIVOT einfach nicht richtig arbeiten lassen. Alle Vorschläge willkommen:

SELECT (SELECT 
       COUNT(*) 
      FROM ImportItem 
      WHERE BodyTypeID = 1) 
     AS [Sedan] 
     ,(SELECT 
       COUNT(*) 
      FROM ImportItem 
      WHERE BodyTypeID = 2) 
     AS [Sport utility] 
     ,(SELECT 
       COUNT(*) 
      FROM ImportItem 
      WHERE BodyTypeID = 3) 
     AS [Sport coupe] 
     ,(SELECT 
       COUNT(*) 
      FROM ImportItem 
      WHERE BodyTypeID = 4) 
     AS [Station wagon] 
     ,(SELECT 
       COUNT(*) 
      FROM ImportItem 
      WHERE BodyTypeID = 5) 
     AS [Convertible] 
     ,(SELECT 
       COUNT(*) 
      FROM ImportItem 
      WHERE BodyTypeID = 6) 

     AS [Coupe] 
     ,(SELECT 
       COUNT(*) 
      FROM ImportItem 
      WHERE BodyTypeID = 7) 

     AS [Roadster] 
     ,(SELECT 
       COUNT(*) 
      FROM ImportItem 
      WHERE BodyTypeID = 8) 

     AS [Mini van] 
     ,(SELECT 
       COUNT(*) 
      FROM ImportItem 
      WHERE BodyTypeID = 9) 
     AS [Pick-up] 
     ,(SELECT 
       COUNT(*) 
      FROM ImportItem 
      WHERE BodyTypeID = 10) 
     AS [Hatchback] 
     ,(SELECT 
       COUNT(*) 
      FROM ImportItem 
      WHERE BodyTypeID = 11) 
     AS [Cargo van]

SELECT COUNT(CASE WHEN BodyTypeID = 1 THEN 1 END) AS [Sedan], 
     COUNT(CASE WHEN BodyTypeID = 2 THEN 1 END) AS [Sport utility], 
     COUNT(CASE WHEN BodyTypeID = 3 THEN 1 END) AS [Sport coupe], 
     etc.. 
FROM ImportItem 

oder

SELECT [1] AS [Sedan], 
     [2] AS [Sport utility], 
     [3] AS [Sport coupe], 
     ect.. 
FROM (SELECT BodyTypeID FROM ImportItem) t 
PIVOT (COUNT(BodyTypeID) FOR BodyTypeID IN ([1],[2],[3],etc..)) p
