Re: Even more embedded SQL....

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 with
the user, and even he's not sure what he wants here.
I'm leaning more towards starting from the beginning of the file (No matter
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.
