I recently saw a set of programming standards that stated it was better not to use an ORDER BY clause on a SELECT statement. Instead SELECT into an internal table and use SORT. The actual statement was....."In most cases it is preferable to do the sorting within the ABAP program instead of on the database server. That means: fill the internal table via a SELECT statement and then sort via the SORT statement instead of coding a SELECT u2026 ORDER BY. The sorting of large amounts of data on the database server affects the performance of all users on the system, whereas the sorting within the ABAP program u2018onlyu2019 affects the application server. However, if an index exists on the table that can be used for the sorting then the SELECT u2026 ORDER BY doesnu2019t cause any undue strains on the system."
I think this is no longer correct particularily with regards to Systemi/iSeries which we normally run in 2 tier mode.
What are people opinion on this?
