How to Select Top 100 rows in Oracle?

Question

My requirement is to get each client\'s latest order, and then get top 100 records.

I wrote one query as below to get latest orders for each client. Internal query works

Answer 1

First 10 customers inserted into db (table customers):

select * from customers where customer_id <=
(select  min(customer_id)+10 from customers)

Last 10 customers inserted into db (table customers):

select * from customers where customer_id >=
(select  max(customer_id)-10 from customers)

Hope this helps....
