Also you want to try reversing you arguments to st_dwithin( and put the

The order will make no difference. It is up to the planner to
Hi!,
In my app I get a MULTILINESTRING and want to insert it as MULTIPOLYGON. I
think there's an easy way but I did't found, can anyone bring some light?
Thanks in advance

Hi,
This is the recipe I found in the past to get it done:

It worked well for me.

Hello!
I have a table with two text fields lat and long of character varying
type.
I've created a field the_geom with type geometry.
How do I calculate the_geom field with an sql query?
The table is huge - about 1.5 million records, so I think the fastest way to
do this is to use pointfromtext
Another option if your data is all within a relatively local area is to
project your data into a suitable projection for that data (ST_Transform),
create an index on the projected data and then use ST_DWithin which will
automatically do the /ST_Expand behind the scenes. Planar math is much
update mytable set the_geom=st_setsrid(st_makepoint(lon,lat),4326);

But his lat/lon are character varying so I think it would be more like
update mytable set the_geom=ST_GeometryFromText('POINT(' || long || ' ' || lat
|| ')',4326)

Thanks for the response, Sandro.I've posted a test case on Dropbox
at http://dl.dropbox.com/u/14591732/foo_reload.sql. This SQL script
will create a table called foo_reload with three features. Here's
my sample session:
# \i /tmp/foo_reload.sql
[load statements removed]
# select gid,
Concatenation of strings geomfromtext or cast to numeric makepoint, I'm not
sure which would be faster, but both will work.
So (as below)
update mytable set the_geom=ST_GeometryFromText('POINT(' || long || ' ' || lat
|| ')',4326)
or
update mytable set
Interesting -- I can confirm too. When I do a ST_Dwithin check things
behave right.
select gid, ST_NPoints(the_geom),
ST_Distance(the_geom,ST_GeomFromText('POINT (-115.04252 36.05137)', -1)) As
dist ,
ST_DWithin(ST_GeomFromText('POINT (-115.04252 36.05137)', -1),
the_geom,0.001) from

Thanks Sandro! I'm seeing updates regarding this on the dev list,
but I'll add myself as a CC to the ticket too.
