@MrNed: i tried your given query it is giving me only 2 results :(

MrNed

OK, not sure why. Do you understand what I am trying to do with my query? It's not clear what you want, I'm assuming you want 10 distinct books, each with one row per author. So the final output will be at least 10 rows, maybe more.

@MrNed:
10 books records but one book author can be more then 1 so records will be more then 10 which book have more then one author for example "AB book" have 2 author 1:XY 2:YZ except this book all books written by one author so record will be 11 because of "AB book" because its duplicating ...

MrNed

So what does the inner part of my query give you:

select * from (
SELECT
USA_BOOKS.PUB_ID id,
USA_BOOKS.DETAIL_FILE_URL detailFileURL,
USA_BOOKS.PUB_FIRST_EDN_YEAR editionYear ,
USA_BOOKS.TITLE,
USA_BOOKS.WHAT_IS_NEW_IMAGE WHATISNEWIMAGE,
USA_BOOKS.IS_USA
FROM
USA_BOOKS_en USA_BOOKS
ORDER BY TO_DATE(USA_BOOKS.PUB_POSTED_DATE, 'MM dd yyyy') DESC , USA_BOOKS.PUB_ID ASC
)
where rownum <11

PRF.PRF_ID AS prfId,
PRF.PRF_NAME AS prfName,
PRF.PRF_IS_CLICKABLE AS prfIsClickable,
profiles.PRF_TYPE prfType

PRF.PRF_ID = profiles.PRF_ID
ORDER BY TO_DATE(USA_BOOKS.PUB_POSTED_DATE, 'MM dd yyyy') DESC , USA_BOOKS.PUB_ID ASC, profiles.PRF_TYPE ASC

when im writing this im getting result which u can see screen shoot above from that result i want 10 records but as i told u the condition 10 records should be books but it'll not apply on authors 10 books but if more then one author of one book it could be 12 records or 11 records because of author record
