Sample Solution:
-- Selecting a concatenated string of 'first_name' and 'last_name' as 'Full_Name',
-- along with 'hire_date', 'commission_pct', a concatenated string of 'email' and 'phone_number'
-- as 'Contact_Details', and 'salary' columns from the 'employees' table
SELECT first_name || ' ' || last_name AS Full_Name, hire_date, commission_pct,
email || ' - ' || phone_number AS Contact_Details, salary
-- Specifying the table to retrieve data from ('employees')
FROM employees
-- Filtering the results based on the condition that 'salary' is greater than 11000
-- or 'phone_number' has the pattern '______3%'
WHERE salary > 11000
OR phone_number LIKE '______3%'
-- Sorting the results in descending order based on 'first_name'

Code Explanation:
The said query in SQL that retrieves the first name and last name concatenated into one column, "Full_Name", using the "||" operator, the hire date, commission percentage, email and phone number concatenated into one column "Contact_Details", and the salary from the 'employees' table.
The result is filtered to only include rows where the value in the "salary" column is greater than 11000 or where the value in the "phone_number" column starts with a 6-digit number ending with "3".
It is sorting the result based on the "first_name" column values that are used to sort the results in descending order.
