<P><FONT SIZE=2>ST_GeomFromText takes the form ST_GeomFromText('POINT(' || raw.x || ' ' || raw.y || ')', 102249)<BR>
<BR>
Anyrate for point geometries its more efficient to use ST_MakePoint so something like<BR>
<BR>
<BR>
UPDATE recent<BR>
SET xypoint = ST_SetSRID(ST_MakePoint(raw.x, raw.y),102249) <BR>
from raw<BR>
where recent.casenum=raw.casenum;<BR>
<BR>
Hope that helps,<BR>

When I attempt to update a geometry column from a field in another table<BR>
with:<BR>
<BR>
UPDATE recent<BR>
SET xypoint = ST_GeomFromText((raw.x, raw.y),102249) <BR>
from raw<BR>
where recent.casenum=raw.casenum;<BR>
<BR>
I get:<BR>
<BR>
*SQL error:*<BR>
<BR>
ERROR: function st_geomfromtext(record, integer) does not exist<BR>
LINE 3: xypoint = ST_GeomFromText((raw.x, raw.y),102249) <BR>

HINT: No function matches the given name and argument types. You might need to add explicit type casts.<BR>

Probably something simple, but I'm not seeing it.<BR>
