SQL Fiddle Exercise 10 - Date Calculations

Calculate the number of days which have elapsed between the date of each sales and today's date.

Remember the function to return today's date is GETDATE(). Your result will vary based on the date when you run your query!

Now filter this to only include events that happened within the last 6 months. Use DataAdd() with Between to achieve this.

For the data of 21st June 2021 this returns 20 rows (feel free to substitute GETDATE() with this date to test your query).

See the answer here.
