Thanks for the response. By spatially enabled, I mean, has a geometry<br>
column, and I wish to use that column for comparison operators, such as<br>
st_within(). Furthermore, since I am adding the column to a table of<br>
data, then setting the geom column to table lat/lon values, I needed to<br>
use addgeometrycolumn (at least I think that I need to do that).<br>
<br>
Anyhow, your query gives me just the information that I need. Thanks!</span></font></p>

Subject: Re: [postgis-users] schema name for a temp table?<br>
<br>
SELECT nspname FROM pg_namespace WHERE oid = pg_my_temp_schema();<br>
<br>
But what exactly do you mean by "spatially enabled"? Any table
with a<br>
geometry column is "spatially enabled". It may not be
registered with<br>
the geometry_columns metadata table or have spatial constraints on it,<br>
but it is capable of holding spatial data.<br>
<br>
ie.<br>
CREATE TEMP TABLE test (id integer, the_geom geometry);<br>
\d<br>
Table "pg_temp_11.test"<br>
Column | Type | Modifiers<br>
----------+----------+-----------<br>
id | integer |<br>
the_geom | geometry |<br>
<br>
Cheers,<br>
Kevin<br>
