Exercise

Performing an anti-join

In our music streaming company dataset, each customer is assigned an employee representative to assist them. In this exercise, filter the employee table by a table of top customers, returning only those employees who are not assigned to a customer. The results should resemble the results of an anti-join. The company's leadership will assign these employees additional training so that they can work with high valued customers.

The top_cust and employees tables have been provided for you.
