John,
You say "Show me all cities within 4 minutes from this longitude/latitude."
I propose to search in a square around your location, ie make a search lat +- 4
miles and long +- 4 miles.
You will get a few occurrences and then refine the search to a circle with
geodesic functions.
Luc,
For Find and replace, try this method

Hey Chuck,
Not sure what “hash and stir” means?
Matching data requires one kind of index for speed and doing a radial search
another.
In the db where I only have 1/2 million records with longitude as a real the
index returns a range quite quickly. So I’ll keep it for the radial search.
For
Hey Peter,
I have already added and split out the longitude into separates fields. So I
have the original longitude as a real and I have it separated into two other
fields.
There are only 360 integer longitudes (ignoring the decimal part) possible.
Potentially -180 through +180. In this case

Sure you hash and stir that, when searching for a particular lat/long
combination you has entry and search
This will not help in distance calculations
How about this for a create a concatenated key that has two parts for each

Did you try clearing the local resources and start over?, we have had
unexplained issues on specific machines that went away when we started fresh.

John,
I do not think using text for dat that can be represented by number is a
good idea. It require more memory - do not forget that Unicode uses 2 bytes
for each character - and manipulation of bigger data structures is slower,
but, especially, string manipulation, including comparison,
I have tried that as well. I added change user after trying to log in as
designer. Result crash. Logging in as administrator. Result crash. Change
user. Result crash

Chuck,
Just to make sure, you are executing that command on a client, not on the
server with a stored proc or Execute on server right?

Hey Chuck,
Given my last response and my needs…
I am trying to visualize how a hash would work? Can you give me an example
using a longitude and latitude?
Thanks,

Hi Arnaud,
Hmmm...
I think I would like the data to be obvious to my eyes when I look at it.
My initial goal was simply to be able to match up a location with a missing
Olson Timezone ID. Import the data, fix the data in the much larger db, and
then export it back out to reimport into it’s
Hi Arnaud,
I have split out the longitudes into a text and real component. I have
formatted the longitudes as “000” and if west of GMT prefixed with “-“ and if
east prefixed with “+“. I'll do something similar with latitudes and then try
building some radial searches and see.
Since all string
Tried that with same result

What if you open a new process method with the one line?
I call OPEN ADMINISTRATION WINDOW and it does work, but I have it in its own

You could use a hash and store it. I have a sequence that is too long to query
and that is what I did works like a charm.

I'd think the opposite, an index based on a "fixed length"
