Re: v5r4: how to prompt user for selection criteria, then use that selection criteria to build SQL and input several joined files to create a new file?

Hi Vern - hope all is well!

As I was reading your response, I am also reviewing your Open Lab: QM: Back to the Future with SQL!

Remember that one?

Im glad I am a pack-rat and filed those away - nice job with the lab!!

Thanks.

Hi Joel

I think QMQRY combined with a command and a CL command-processing
program is the easiest (best?) way to do this.

In the command you can define parameters for the date range with
appropriate formatting if you want.

In the CPP you muck about with the date value as needed and do the
STRQMQRY with appropriate SETVARs.

Use the OUTPUT parameter to *OUTFILE in STRQMQRY - Ba-Da-Bing!

On v5r4

What is a simple and straight-forward method to


* Present a screen to a user

* Prompt for date-range

* Substitute the date-range into an SQL statement which CREATEs a new file (after joining and filtering several files & rows)

* Execute the SQL


Would a CL command work? Or a DDS screen?

Then can I use SQL in a source member and insert the date range? Or is QMQuery the best way to do this?

(I really don't want to use OPNQRYF with all the nasty quotes to do this - those statements get ugly)

Any suggestions??


Thanks in advance!!
