We used to have end users be the trainers for the new systems people.

We had end users uploading stuff to the iSeries just to be able to run
Query/400 against it.

Definetly a good end user tool.

Evan,
                 We can go back and for on this issue.  The answer to the
original
question is "depends".  It depends on how the need can be fulfilled.  I
like
SQL for querying and QUERY/400 for reporting.  I have used both and both
are
used in a product situation.  I do give it to end-users but only to a very
select few.

Thank you,
Matt Tyler

Hi Matt

this is one of those statements I see from time to time that I like to
challenge :)

If someone wrote a query that outputs to a file with a production file
name
and replace member *yes specified they could certainly "kill" data.

Of course an adequate security scheme would prevent this but I'd hazard a
guess that this might be a vulnerability on just a few systems
