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.

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.

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

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?
