Obtenez tous les articles vendus en fonction d'une collection d'articles à partir d'une table principale dans SQL Server

Cela vous mènera probablement à la majeure partie du chemin. Je n'ai pas mis en place de logique pour déplacer les colonnes récapitulatives car cela ne fonctionnerait que pour deux catégories, et je suppose que vous en avez beaucoup plus.

CREATE TABLE #Master(ItemNo int,[Name] varchar(50), Category varchar(5)) 
INSERT INTO #Master VALUES(10001,'Apple','C1' )   
INSERT INTO #Master VALUES(10002, 'Coffee' ,'C1')  
INSERT INTO #Master VALUES(10003,'Bread','C2')   
INSERT INTO #Master VALUES(10004,'Beans' ,'C2')
