Query an alphabetically ordered list of all names in OCCUPATIONS, immediately followed by the first letter of each profession as a parenthetical
Generate the following two result sets:
- Query an alphabetically ordered list of all names in OCCUPATIONS, immediately followed by the first letter of each profession as a parenthetical (i.e. enclosed in parentheses). For example:AnActorName(A),ADoctorName(D), AProfessorName(P), and ASingerName(S).
- Query the number of occurrences of each occupation in OCCUPATIONS. Sort the occurrences in ascending order, and output them in the following format:
There are a total of [occupation_count] [occupation]s.
- where
[occupation_count]is the number of occurrences of an occupation in OCCUPATIONS and[occupation]is the lowercase occupation name. If more than one Occupation has the same[occupation_count], they should be ordered alphabetically.
Note: There will be at least two entries in the table for each type of occupation.
Input Format
The OCCUPATIONS table is described as follows:
Occupation will only contain one of the following values: Doctor, Professor, Singer or Actor.

Explanation
The results of the first query are formatted to the problem description’s specifications.
