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

As Moneer Kamal said, you can do that simply:

SELECT id, client_id FROM order 
WHERE rownum <= 100
ORDER BY create_time DESC;

Notice that the ordering is done after getting the 100 row. This might be useful for who does not want ordering.
