[postgis-users] create a point fom lat/lon

[Obe, Regina]

You have the lon and lat as part of your string so it wan't read the values.  Also POINT needs to be in upper case.
 
Try instead
 
update iter_rco_2005g
set
the_geom=geomfromtext('POINT(' || long || ' ' || lat || ')', 4326);

hope that helps,
Regina

Subject: [postgis-users] create a point fom lat/lon



Hello all:

I have two columns lat and lon, from these columns I
want to create a point on the_geom column.

this is how i did

update iter_rco_2005g
set
the_geom=geomfromtext('point(lon lat)', 4326);

and

update iter_rco_2005g
set
the_geom=geomfromtext('point(lon, lat)', 4326);

lat an lon are in dd.

I get
ERROR:  Invalid OGC WKT (does not start with P,L,M or
G)

here is a sample data
 mun | loc  |       lat        |       lon
-----+------+------------------+------------------
