With embedded SQL we have more control over whether the query runs on-line or on-JOBQ, and of course embedded can be written to handle complex situations query/400 not well suited to handle.

I have had co-workers run poorly constructed query/400 (e.g. join inventory history file's millions of records with cost master's 1/2 million records) on-line, and bring the 400 to its knees. I show the culprit how to run that on JOBQ, then they do same thing again, acting like the 400 to its knees is some glitch they have nothing to do with.

Are there any performance issues to consider when looking at embedded SQL
versus Query400?

It seems that Query400 might actually run faster, but I can definitely see
the advantages of creating an SQL statement on the fly per se.

Thoughts, comments? Tell me I'm nuts....ok skip the last one, that's a given.


If you bought it, it was hauled by a truck - somewhere, sometime.
