Question

We need to find TOP 10 students (max score 500) from each section of class.

Example :

Section  Name   Total Score  

     A   Paul   499  
     A   Gustuv 498 
         ...upto top 10  

     B   Henrik  499  
     B   John   498   
         ...upto 10

Lets say it has two tables STUDENT and CLASS.

How is to possible to display the results in such a manner using sql in oracle ?

Answer 1

Try…

I don’t have your schema to test…. But you should be able to get the general idea.

with rank_query as (
SELECT section, name, score,
       RANK() OVER (PARTITION BY section ORDER BY score) score_rank
FROM   myTable
)

select * from rank_query where score_rank <= 10;
