    This one-stop-shot-style SQL course will teach you everything you need to know about SQL, from learning various database concepts to writing SQL to interact with the database. 

    Throughout this SQL course I will be using the below methodology to make you think and help in forming the SQL statement. 

  Business Need: 

               Manager asks you to give you a report containing total sales volume for January month by day and city 

               Questions in your mind to build your SQL query 

• Give?                                                                  SELECT 

• What columns?                                                 DAY, CITY 

• Summary?                                                          SUM(VOLUME) 

• Preposition?                                                      FROM 

• Which table contains sales orders data?      SALES 

• Filter?                                                                WHERE SALES_DATE BETWEEN ’01-JAN-2015’ and ’31-JAN-2015’ 

• Grouping?                                                         GROUP BY DAY, CITY

               Combine the above answers to form the below SQL 

               SELECT day, city, SUM(volume)
               FROM sales
               WHERE sales_date BETWEEN ’01-JAN-2015’ AND ’31-JAN-2015’
