Exercise

Having

WHERE is used to filter rows before any grouping occurs. Once you have performed a grouping operation, you may want to further restrict the number of rows returned. This is a job for HAVING. In this exercise, you will modify an existing query to use HAVING, so that only those results with a sum of over 10000 are returned.
