[postgis-users] Fwd: php postgis query - incompete
geometryreturned??<BR><BR></FONT></DIV><SPAN class=gmail_quote></SPAN>Hi
All,<BR><BR><BR>I've have a problem with querying a postgis table from php.
When I run the query in pgadmin I get one geometry result (correct one) and
when I run it in php the geometry gets shortened somehow? I've tested the
pgadmin result in openjump and the route is correct.<BR><BR><BR>I'm trying to
get the wkt of the geom so I can draw it on a map.<BR><BR><BR><BR>Run the
query in pgadmin:<BR><BR>Query: <BR><BR>SELECT gid, source, target,
astext(the_geom) from required_roads_edge where gid IN <BR>
(SELECT edge_id FROM shortest_path('<BR> SELECT gid as id,
source::integer, target::integer, <BR> length::double
precision as cost FROM required_roads', <BR> 568, 600,
false, false))<BR><BR><BR>PGADMIN Result: (sorry I know it's
untidy)<BR><BR>GID, Source, Target, Geom
