Put in the correct schema name below if it isn't public; and you may need to quote your lat/lon field names if they're really capitalized ( i.e. "Latitude", "Longitude"). This should work...
SELECT AddGeometryColumn( 'public', --schema 'CAMDENGPS', --tablename 'the_geom', --field to contain geom 4326, --srid from spatial_ref_sys 'POINT', --type of geometry 2 --dimensions, 1 didn't work. );
Then...
UPDATE public."CAMDENGPS" SET the_geom = ST_SetSRID(ST_Point(longitude, latitude),4326);

[NOVICE] Create GEOM Column
Sent by:
pgsql-novice-owner@postgresql.org
Dear all,
Would appreciate some help. I have created an existing database (with PostGIS extension) andhas a table called CAMDENGPS which is populated with approx 600,000 rows. There are 20 or so columns in the table, two of which are Latitude and Longitude (WGS84). I would now like to create a Geom column with points in, the values of which should be taken from the other columns. Could someone provide me with sample code as to how to do this please?
