Is there a way for me to pivot these rows into columns in oracle?

va9999 :

I have a database table which looks like the attached image

enter image description here I need to query this and be able to show output in the format of BookID, Genre1, Genre2, Genre3

I have read some previous posts on pivoting / use of the MAX function but I am still struggling, I am new to this.

Gordon Linoff :

You can use row_number() and conditional aggregation:

select bookId,
       max(case when seqnum = 1 then genre end) as genre_1,
       max(case when seqnum = 2 then genre end) as genre_2,
       max(case when seqnum = 3 then genre end) as genre_3
from (select bg.*, 
             row_number() over (partition by bookId order by genre) as seqnum
      from bookGenres
     ) bg
group by bookId;
