https://www.hackerrank.com/challenges/the-pads/problemMy Query:
select
case
when occupation='doctor' then name1
when occupation='singer' then name1
when occupation='actor' then name1
when occupation='professor' then name1
else null end as professions
from (
select occupation,name,concat(name,concat('(',(substring(occupation,1,1)),')')) as name1
from occupations)
a
union
select
concat(description,' ', summary,' ', profession)as office from
(select
description,occupation,profession,count(profession) as summary
from (
select
occupation,name,
'There are a total of' as description,
concat(occupation,'s') as profession
from occupations
)a
group by description,occupation,profession
)
bScenario:
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), andASingerName(S). - Query the number of ocurrences 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.Sample Input
An OCCUPATIONS table that contains the following records:
Sample Output
Ashely(P)
Christeen(P)
Jane(A)
Jenny(D)
There are a total of 2 doctors.
There are a total of 2 singers.
There are a total of 3 actors
There are a total of 3 professors.Explanation
The results of the first query are formatted to the problem description's specifications.
The results of the second query are ascendingly ordered first by number of names corresponding to each profession(), and then alphabetically by profession , and then alphabetically by profession.Regards,

It's asking you to generate two result sets, and you're only generating one. In trying to combine the two into one, you've added unnecessary complexity to the query.

Use 2 SELECT statements in the same query.

For example:
[Code]SELECT 1;
SELECT 2;
GO[/query]
That's two statements, run in the same session, with 2 result sets.Thom~
