Question: Thank you so much for that! Can you filter this list to show only the rows in which the employee works in a department which has an employee with the letter J in their name?
SQL: SELECT employee_id ,  first_name ,  last_name ,  salary FROM employees WHERE salary  >   (  SELECT AVG  ( salary )  FROM employees  )  AND department_id IN  (  SELECT department_id FROM employees WHERE first_name LIKE '%J%' )
