Total sales per month

Question

I think this is common, is it?

If you have a table with SALES {Customer_ID, Price, SmallDateTime date}. How do you report all sales per month?

Answer 1

SELECT CONVERT(CHAR(7), SmallDateTime, 120) as Year_Month,
       SUM(Price)
    FROM Sales
    GROUP BY CONVERT(CHAR(7), SmallDateTime, 120) 
    ORDER BY Year_Month
