RE: Need some help with SQL case/when performance

There is no sort that I know of unless SQL is creating one for some reason.


The RPG F spec does not specify a key.
The SQL does not have a where or order by clause.

For your SQL statement- are you sorting differently than the F spec file.
This will be a huge performance hog, if there is not an INDEX already out
there to match your sort.
