[postgis-users] Update field from expression

[Poynter, David]

Greetings PostGIS list,

I am trying to populate a relate field (huc) in a point table
(permit_sites) from the gid field in a multi-polygon table (huc8).

This is what I came up with:

UPDATE permit_sites SET huc = giddy FROM (SELECT h.gid FROM huc8 h,
permit_sites p WHERE ST_Within(p.the_geom,h.the_geom)) AS giddy;

Whence I get this response:

ERROR:  column "huc" is of type integer but expression is of type record
HINT:  You will need to rewrite or cast the expression.

Seems I can't take the hint, I tried casting but it is apparently
impossible to cast a record as an integer, at least for me.

Any suggestions as to how I should proceed would be appreciated.
