chris :
I was working on a problem from Leetcode #185
I could understand the solution but I want to know how to write the query that add a column which indicate the count the people have a better salary than the tuple one. I think it is possible in SQL, but i don't know how to make it right, i always get syntax error. :-/
from Employee e1 (Select count(distinct e2.Salary)
from Employee e2
Where e2.Salary > e1.Salary) as c
For exemple I have such a table Employee:
Id - Name - Salary
1 toto 60000
2 tata 50000
3 kiki 90000
4 lily 70000
5 momo 60000
I want to have such a result:
Id - Name - Salary - Head_count_of_higher_salary
1 toto 60000 2
2 tata 50000 4
3 kiki 90000 0
4 lily 70000 1
5 momo 60000 2
Thanks guys
forpas :
Your subquery is almost correct.
Just remove DISTINCT from COUNT() (although just COUNT(*) would also work) and use it as the new column:
select *,
(
select count(e2.Salary)
from Employee e2
where e2.Salary > e1.Salary
) as Head_count_of_higher_salary
from Employee e1
See the demo.
