MySQL GROUP BY doesn't work when migrated to SQL Server 2012

Question

I\'m moving my Delphi application from MySQL to SQL server 2012. In MySQL I had this query:

SELECT *,(XS+S+M+L+XL+XXL+[1Size]+Custom) as Total FROM StockData  
G         


        

Answer 1

SQL Server is working as expected. You must include all items in your SELECT list in either a GROUP BY or in an aggregate function:

SELECT *,(XS+S+M+L+XL+XXL+[1Size]+Custom) as Total 
FROM StockData  
-- GROUP BY ID,StyleNr,Customer,Color, XS,S,M,L,XL,XXL,[1Size],Custom
ORDER BY StyleNr,Customer,Color

Or you might be able to use:

SELECT StyleNr,Customer,Color, SUM(XS+S+M+L+XL+XXL+[1Size]+Custom) as Total 
FROM StockData  
GROUP BY StyleNr,Customer,Color
ORDER BY StyleNr,Customer,Color;
