LOL = I know Mark - you can tell him that I live and breathe by Visual Explain. And I'll tell him at the next CAAC meeting in December.

Authority has not been an issue, even in this shop, where we are limited on our production LPAR, less restricted on the development one.

Now I am a SME for DB2 at COMMON, so I might be an exception. It may be an education matter - the help for VE is very helpful, right-click is a great help, and the optimization PDF will be of benefit to anyone with the interest.

I think there is more interest than one might think - and if nicely documented in the RDi help, it could be very useful. Maybe I'll put in a requirement through CAAC, as well - the more inputs, the better, eh?

I have thoughts about that too.

On that way from RDi to SQL script editor
Strip DECLARE .. prefix and put in comment
Let the developer play with just the SELECT statement
On the way back, prepend from the DECLARE comment

Just thoughts
BTW, would you see what I proposed as a sufficient solution to RFE

Regarding the RFE on visual explain.
When I was discussing this with Mark Anderson he didn't think that
developers had the authority or interest or expertise to use visual explain
to optimize queries beyond noticing the need to index certain tables. But
I see 46 votes on this RFE. Are developers making active use of Visual

That's clear Jon, thanks. This thread is morphing into a discussion on
integrating Data Studio with RDi. Imagine you have an existing SQLRPGLE
program with a DECLARE CURSOR as below. You'd like to make some changes
to that SQL statement, what does one do?

Rectangle select, copy, tab to Data Studio, paste. Replace the host
variables with literals, test. Edit, test, repeat. When happy with the
new SQL statement, copy in Data Studio, tab to RDi, select, paste.
Adjust formatting. Save, compile, test. Forgot to replace literals,
wonder why program doesn't work. Replace literals with host variables.
Save, compile, test.

It's better than a sharp stick in the eye, but that's a low bar :-)

So if there was an easy way to get embedded SQL into an SQL script

I would love to have the test/debug tool/IDE be able to 'declare'
variables :REF_FILE and :REF_LIBR as well as populate them with values
then execute this code as-is. Once my SQL is working properly, I could
cut / paste it back into my HLL as-is without having to remove literals
replace them with host variables.
