I'm working on a screen in our webapp where we're using a dojo widjet to create

Hi Chris:
This is a problem we first tried to figure out when we went to the Web. The
easiest way for us was to save off the client select using SAVE.LIST. You
will need a few variableS to keep track of where you are CURRENT.PAGE.NO,
ITEMS.PER.PAGE and NEW.PAGE.NO. Use you math skills you

I'm betting the solution also needs indexing, because you want to pick
up where the last list left off and you don't want to wait for a select
to return to save the list. So, SAMPLE isn't really a solution but
indexing is. We do this all the time, but we have to use indexing. In

I agree with Bill, using an index is your best solution. Are you able to apply

I guess my question is regarding how to traverse the index. In this case the
field we're using is the @ID, so it's
indexed by default. Below you stated that we have to traverse in BASIC, is this
using the SAVE.LIST approach that Doug

Curt,
My problem is understanding how to traverse the query. Our dropdown is
paginated, we can specify the # of results per paginated drop-down so it being
super long or short
isn't an issue. The problem is getting the SELECT statements/UniVerse to match
what we want the dropdown to do.

Look at the BSCAN directive. It allows you to scan and traverse B-Tree type

Chris,
Bscan is a universe command that will let you traverse a secondary index. Say
the last company on the page was ABC Company, your BSCAN commands match value
could be Abc and then step thru the list with a loop. The UV docs description

This works with UV, and not the SQL solution.
However, I did find if you need to do a sorted select, you first have to do the
select
then a second select to pull the rows / pages
SELECT CLIENT WITH NAME LIKE A...
SELECT CLIENT WITH PAGE = 4
SELECT CLIENT WITH NAME LIKE A... AND WITH PAGE = 4
To clarify that statement, if you are SORTING your results you must
make it two statements to get the correct results.
SELECT CLIENT WITH NAME LIKE A... BY NAME
SELECT CLIENT WITH PAGE = 4
SELECT CLIENT WITH NAME LIKE A... BY NAME AND WITH PAGE = 4 Will give
you the page 4 of the unsorted

You understand that the value for PAGE is specific to the SELECT / LIST
which is why when you list the names, it displays as page 1, which is
based on that output. When you did the select, it pulled from the page
numbers from that selection.
As to how it works. If I understand correctly
Thank you! We don't do a lot of double select statements in our programs, I
assume you do the 1st SELECT and then do some sort of CAPTURED or PASSLIST

to pass the first selected values into the 2nd SELECT.
