It's not really interactive vs batch...

It's OPTIMIZE = *FIRSTIO vs OPTIMIZE = *ALLIO

STRSQL and Run SQL Scripts default to *FIRSTIO, embedded SQL defaults to
*ALLIO

But either can be changed.

This is also true - generally speaking interactive will try for faster
response, so it gets the first records. Batch tends to go for all.

The only situation that is truly interactive, IMO, is a display session.
Running statements in remote connections will tend toward the batch
approach.

Digging into my memory, seems to me that the optimizer may decide
differently on batch vs interactive execution. but it's been a while...

I agree with using Visual Explain - it would show any difference in
what the optimizer does.

Of course, when the environment changes, the optimizer might make
different choices.
