Sample Solution:

-- Selecting first name, last name, and shift from the vEmployeeDepartmentHistory view
SELECT 
    -- Selecting the FirstName column from the view
    FirstName, 
    -- Selecting the LastName column from the view
    LastName, 
    -- Selecting the Shift column from the view
    Shift   
-- From the vEmployeeDepartmentHistory view
FROM 
    HumanResources.vEmployeeDepartmentHistory  
-- Filtering records to include only those where the department is 'Quality Assurance' and the shift is either 'Evening' or 'Night'
WHERE 
    Department = 'Quality Assurance'  
    AND (Shift = 'Evening' OR Shift = 'Night');

Explanation:

• This SQL code retrieves the first name, last name, and shift of employees working in the Quality Assurance department during either the Evening or Night shifts.
• The SELECT statement specifies the columns to be included in the result set.
• The FROM clause indicates the view from which data is being retrieved, which is the HumanResources.vEmployeeDepartmentHistory view.
• The WHERE clause filters records to include only those where:
• The department is 'Quality Assurance'
• The shift is either 'Evening' or 'Night'.

Sample Output:

firstname|lastname      |shift  |
---------+--------------+-------+
Sootha   |Charncherngkha|Night  |
Andreas  |Berglund      |Evening|
