Re: Merging Files

Been there; done that; saw the movie.

I don't intend to make this a habit.

Very cool, Jerry - glad it worked. Of course, there are the caveats others have 
mentioned that I left out, especially those connected with logicals based on 
files in different libraries. But you've been around enough to know where to 
look for help in that arena.

Vern,

I set up a quick test LF. Physicals in multiple libraries. Worked fine. Even processed a document to add to the current year's history and it showed up in the multi-format LF. The only problem was a much older PF (2001) that is missing a field common to all of the other PFs I think I can live without flashbacks to 2001! So life is (temporarily) good.

Thanks.

Hi Jerry I'm trying to remember if this is possible - have a single format in the LF but name several files in the CRTLF command - not sure if it can cross library and file boundaries - it can definitely merge several members of the same file in one logical. All the Pfiles have to have the same format, of course - I think. HTH Vern At 07:30 AM 6/21/2006, you wrote:

Thanks to everyone.

I do have a project to merge all of the tables into a single table. Legacy code, especially queries, are going to be a pain.

I definitely need to get into SQL more; I pull out Conte and Cravitz's book whenever there's down time. I use pretty simple statements, such as Select and Update, frequently but need to become better versed in the subject. I'll read up on the Union as soon as possible.

Scott's solution for legacy code was what I was trying to do, except that I had defined multiple record formats, such as R FORMATR PFILE(PF1) K KEY R FORMATR PFILE(PF2) K KEY

Which was the way the DDS manual and InfoCenter both illustrated it. But their examples were merging, say, an Order Header and Order Details, not identical tables. The DDS compiler choked on that, obviously.

Again, thanks. * Jerry C. Adams *IBM System i Programmer/Analyst B&W Wholesale Distributors, Inc.* * voice 615.995.7024 fax 615.995.1201 email jerry@xxxxxxxxxxxxxxx

Not sure how many files are in each library and not sure of the size of your files so this may not be an option, but I have some files like that that I wrote a query for that appends the file for one year to another year and I write the year to the beginning of each file. In the end, I have one big file with multiple years. Of course, you can always create a view across the years like someone mentioned -----Original Message----- From: midrange-l-bounces@xxxxxxxxxxxx [mailto:midrange-l-bounces@xxxxxxxxxxxx] On Behalf Of Jerry Adams Sent: Tuesday, June 20, 2006 3:51 PM To: Midrange-L Subject: Merging Files We have separate libraries for each year's history. In order to perform inquiries across multiple years rather than multi-defining each PF in the program (which, honestly, is what I have been doing), I would like to read them as a single file.

These tables have the same identical layout (fields, format names, file names); just in different libraries. I tried using a multiple format LF but, naturally, it blew off because the record format names are the same.

Is there any way to read these two physical files via a single file statement, or am I just spinning my wheels in the sand here?
