Sample Solution:

-- Selecting all columns (*) from the 'departments' table
SELECT *

-- Filtering rows based on the condition that the 'DEPARTMENT_ID' is in the result set of a nested subquery
FROM departments

-- Subquery to find 'DEPARTMENT_ID' values where the 'EMPLOYEE_ID' is in the result set of another subquery in the 'employees' table
WHERE DEPARTMENT_ID IN
    (SELECT DEPARTMENT_ID
     FROM employees

     -- Subquery to find 'EMPLOYEE_ID' values where the count of occurrences is greater than 1 in the 'job_history' table
     WHERE EMPLOYEE_ID IN
         (SELECT EMPLOYEE_ID
          FROM job_history

          -- Grouping 'EMPLOYEE_ID' values and filtering based on the count of occurrences
          GROUP BY EMPLOYEE_ID
          HAVING COUNT(EMPLOYEE_ID) > 1)

     -- Grouping 'DEPARTMENT_ID' values and filtering based on the maximum 'SALARY'
     GROUP BY DEPARTMENT_ID
     HAVING MAX(SALARY) > 7000);

Sample Output:

department_id	department_name	manager_id	location_id
80		Sales		145		2500
90		Executive	 100	1700

Code Explanation:

The said query in SQL querying data from three tables: "departments", "employees", and "job_history".
The query starts by selecting all columns from the 'departments' table. The rest of the query specifies the conditions for which rows should be returned.
The conditions are specified using the "WHERE" clause in the subquery retrieves the department IDs from the 'employees' table where the employee IDs are returned from another subquery.
The second subquery retrieves employee IDs from the 'job_history' table where the employee has more than one job history entry.
Finally, the outermost subquery groups the department IDs by the "DEPARTMENT_ID" column and returns only those departments where the maximum salary is greater than 7000.
The result of this query will be a table containing all columns from the 'departments' table, but only for those departments that meet the conditions specified in the "WHERE" clause.

SQL Subqueries Exercises: Display the the details of  departments which max salary is 7000 or above for  those employees who already done one or more jobs.

Alternative Solution:

Using JOINs:


SELECT d.*
FROM departments d
JOIN employees e ON d.department_id = e.department_id
JOIN job_history jh ON e.employee_id = jh.employee_id
GROUP BY d.department_id
HAVING COUNT(e.employee_id) > 1
    AND MAX(e.salary) > 7000;
