Hi All,
I have installed PostGIS 1.2.1 version but I could not able to find out

Just to add to what Mark said. I had this issue when switching over
from 8.1 to 8.2. It was a problem with the GEOS library interaction with
8.2 which I think was fixed with Geos 3.0.0rc4 and above (there might
have been a slightly lower version that fixed it.)
If you are running 8.2 with Geos 2.
This was introduced in I think in 1.2.2. In short st_dwithin() is a
short-hand way of writing
geom1 && geom2 AND distance(geom1, geom2) <= somedistance
Hope that helps,
Regina

The only guaranteed way is to add the records in geometry_columns
manually. With a command something like
INSERT INTO geometry_columns(
f_table_catalog, f_table_schema, f_table_name,
f_geometry_column,
coord_dimension, srid, "type")
VALUES ('', 'public', 'sometable',

Alan,
MySQL's spatial functionality is very limited IMHO -- they only have a bounding
box intersection, similar to the && operator, and nothing like a "within" or
distance function. So if you have, say, a lot of rectangular tiles and a query
shape that is a large semi-circle, both MySQL and pos
