Let me just say that the idea behind this project took the user 2 hours
(without interruption) to explain what he wanted.
The way it will be "clustered" could be as follows
All the items that are red, over 7 inches tall, over 4 inches wide. Could
be one cluster. (Category/Sub-category)
All the items that are over 7 inches tall, over 4 inches wide. Could be
another cluster (Category/Sub-category)
That's right, One item can be in multiple clusters.
So the ability to sort the data by different "columns" is a definite entity
that the user wants.

Your last comment is echoed by me regularly.  There's no new problems,
just problems we haven't seen yet.  Someone has though, and has solved
it already.  This is a good place to meet that guy or gal.

Let me see if I understand your problem.  When you say "cluster like
items"  the idea of filtering comes screaming out of the air at me.
Your users don't care about the order within the cluster; only that the
cluster be like-stuff.  All the red ones, all the tall ones, all the
broke ones, etc.  Is that what you are saying?




Alan Shore wrote:
Sorry Booth, I already suggested that. The user needs the ability to see
multiple records on the screen.
With the user having the ability  to sort the data down in whatever way
they desire, it will help them to "cluster" like items together, so that
they can choose like items for the same Category/Sub-Category.
Like I said before, I didn't say that this project was easy.
However, I hope nobody misconstrues any of my remarks, because the
responses I have received from EVERYBODY, has shown me just how important
that this e-mail group/list is in pooling knowledge.

A subfile has a limit of 9999 records.  Its easy to program to stop at
that limit, but really, at that point a subfile has little use.  Thats
why I suggested a filter earlier.  Later I saw your post where the users
need to process all the records.  Well, ok.  But they aren't going to
process 65,000 in one sitting.  If they really are going to process all
of the records, one after another, why display 10 at a time, anyway?
Display them one record at a time, and allow the page keys to page up
and down through the main file, one record at a time?  Then, have the
various possible sorts set on by F-key(s) and use logicals as was
suggested by someone earlier.

Making changes as you suggested resulted in the program errors out on
the
10,000th record to the subfile.

Oh well. Never mind

Thanks,

I've never used it, but I "wrongly" assumed that it was designed so that
you could do more than 9,999 records.

Michael,

The DDS Manual specifies that a program to system field should be 5S0 if
used for these keywords. But, it also quite explicitly states that the
maximum number of records in a subfile is 9999.

In the control record. You can chose to enter "Records in subfile" or
name
a field in "Program-to-system field" by putting an "8" as the option in
SDA.  If you use program-to-system field you must define the field in
the
control records dspecs.  You will create this field just as you would
for
a
hidden field but instead of using an H, you would use a P.  The biggest
you
can define this field is 5, 0 (it may be the only size that you can
specify).

                            Define Display Layout

You see in the bottom,I've entered a program to system field with the

In the RPG program, you will then Eval    SFLSIZE = *HIVAL or 99999

Could you be more explicit.
Are you saying that there is a way to load 99,999 records to a load all

I believe that you can use a program-to-system field that will allow
you
to
create 99,999 records.

Booth - you and I must be on the same wavelength, or in mutual
mind-meld
mode or something.
I want to take time to thank everyone who has replied to my question,
with
suggestions, ideas, thoughts, other questions and especially examples.

I think I have a handle on everything that I need in relation to what
is
required for SQL and Dynamic sort building, but what bothers me is the
position to aspect of SQL, where the file data is rebuilt, with the
first
record being equal to or greater than the value that was requested to
be
positioned to. The problem of paging up from that point (before the
first
record) will mean yet another re-creation.
So I was thinking of a couple of things
1/. Load the first 9,999 records into a load all sub-file.
If the user wants to go above that, recreate the data and load the next
9,999 records etc. etc.
If the user wants to position to a value AND its within this 9,999 NO
PROBLEM
If its outside the range , recreate the data and load the applicable
9,999
records into the sub-file.
2/. Create a file (via DDS) with all the fields defined
COL1, COL2, COL3, COL4, COL5, COL6, COL7 and an additional field which
is
in effect equal in size to ALL the fields CONCATENATED. This field
would
now be the key of the file, and depending upon what sort is required,
build
this field accordingly
for example
if the sort is COL1, COL2, COL3, COL4, COL5, COL6, COL7, the this key
field
is created as
COL1 concat COL2 concat COL3 concat COL4 concat COL5 concat COL6 concat
COL7
and then use regular RPG to handle the page up, page down, position to
page-at-a-time sub-file
Anybody any thoughts on either of these 2 ideas?

May I make a suggestion here?

A small, but very helpful step might be to put filters in place before
the process starts, or at any time in the process.  Let the user set
the
filters with an F-key.  Point out to the users the problems it solves
for them, and I believe they will get on board. "I want all of zip code
12345 sorted by color"  becomes a breeze to do.

If they will filter so that the number of records of interest remains
below about 2500 records then you can do a load-all into an array and
the sorting becomes a piece of cake.  Heck, it even allows a scroll
bar,
which really is wonderful if for no other reason than that they can
pull
the subfile up or down one record at a time with no coding required on
your part.  (Yes, thats right.  One record at a time up or down.  Piece
of cake.)

That's one thing I'm still playing around with in my head. I've talked

I'm leaning more towards starting from the beginning of the file (No

how its sorted, for each RE-SORT)as I'm pretty sure this will be
easier
to
code for.

So, then, when the user clicks on the other column, say color, will
the
first record of the new subfile be the first record of the field value
in record 1 of the subfile?

Lets say I have a subfile sorted by year and the first displayed
record
happens to have a value of "White" in the color column.  When I click
the color column does my new subfile start with "White"  or with the
lowest color alpha value, say... "Amaretto" or "Blue" or "Cyan"?

Thanks Booth
The answer is for the WHOLE data (ALL 15,000 records) to be sorted
(ascending/descending) based upon whatever combination of the 7
columns
the
user wants, hence the Dynamic sort. The order by of the SQL statement
will
have to be dynamically built.

What if you present data by, say, year.  Then the user clicks the
column
headed "Color".  Do you want the 15 items shown by column "year" to
be
sorted by color, or so you want all 15000 records sorted by color
first,
then by year?

(Also, clicking the sort column a second time could present the same
data in reverse order (ascending vs. descending)

Thanks for your reply Michael, but I think you misunderstand what I
am
looking for.
If my screen is displaying 7 different columns, the user wants to be
able
to sort the data by ANY combination of those columns

for example
Col1, Col2, Col3, Col4, Col5, Col6, Col7
and then (by magic) the same data by
Col7, Col6, Col5, Col4, Col3, Col2, Col1
AND THEN
Col6
Or maybe
Col5, Col6, Col1

This would mean building the ORDER BY within the SQL statement based
upon
the request of the user.
So as per my original request
if anyone can help me, I am looking for an example of embedded SQL
and
Dynamic
Sorting Subfiles - Page at a time (with the ability to position to a
particular piece of data)

However - Michael, I will still look up your suggestion

Thanks in advance

Look in the archives for uses of the CASE statement.  I don't
remember
the
exact syntax at this time, but you can use the case statement to
order
by
a
specific field based on the user selection.

  Hi All,

  I have been given a project that requires the need to display,
within
a
subfile, the data from 2
  separate files with the ability to sort that data from any number
of
different columns. So I
  thought to myself, this smacks of embedded SQL and Dynamic Sorting
Subfiles. The unfortunate
  thing is that the data I have to display is over 15,000 records
long
(and
growing) so if anyone
  can help me, I am looking for an example of embedded SQL and
Dynamic
Sorting Subfiles - Page at
  a time (with the ability to position to a particular piece of
data)"
  Some title for an article huh? If anyone has an example of what is
required, or could point me
  in some direction, I would be very grateful.
