Sample Solution:

-- Selecting the average vacation hours and the total sick leave hours
SELECT AVG(VacationHours) AS "Average vacation hours",   
    SUM(SickLeaveHours) AS "Total sick leave hours"  

-- From the HumanResources schema's Employee table
FROM HumanResources.Employee  

-- Filtering the results to include only rows where the job title starts with 'Vice President'
WHERE JobTitle LIKE 'Vice President%';

Explanation:

• The SQL query retrieves data from the Employee table within the HumanResources schema.
• It calculates the average vacation hours and the total sick leave hours for employees with the job title starting with 'Vice President'.
• The AVG() function calculates the average of the vacation hours.
• The SUM() function calculates the total of the sick leave hours.
• The WHERE clause filters the results to include only rows where the job title starts with 'Vice President'.
• The LIKE operator is used for pattern matching.

Sample Output:

Average vacation hours|Total sick leave hours|
----------------------+----------------------+
   25.0000000000000000|                    97|
