[mapserver-users] getfeatureinfo problems

Fri Jun 26 08:59:30 EDT 2009

Jukka,

Thank you, I've tried the SQL statement:

DECLARE mycursor BINARY CURSOR FOR SELECT asbinary(force_collection(force_2d(tc_vlak_geometry)),'NDR'),geoidn::text from "NL.IMRO.0026.SVBBU-0001" WHERE (geoidn='geoidNL.IMRO.0026.SVBBU-0001') and (tc_vlak_geometry && setSRID( 'BOX3D(155984.407968748 468982.233317728,156024.590926508 469022.416275488)'::BOX3D,28992) )

with the first DECLARE part omitted, so:
SELECT 
asbinary(force_collection(force_2d(tc_vlak_geometry)),'NDR'),geoidn::text 
from "NL.IMRO.0026.SVBBU-0001" WHERE 
(geoidn='geoidNL.IMRO.0026.SVBBU-0001') and (tc_vlak_geometry && 
setSRID( 'BOX3D(155984.407968748 468982.233317728,156024.590926508 
469022.416275488)'::BOX3D,28992) )

This returns two rows.
I've tried
SELECT 
"geoidn"::text,"idealisatie"::text,"tc_multi_geometry"::text,"tc_lijn_geometry"::text,"tc_punt_geometry"::text,asbinary(force_collection(force_2d(tc_vlak_geometry)),'NDR') 
from "NL.IMRO.0026.SVBBU-0001" WHERE geoidn = 0

also, which returns 0 rows.
This is as expected from this query as it asks for WHERE geoidn = 0
geoidn never is 0.

Why does mapserver come to this query? I've never asked for geidn to be 
zero!
If I remove the WHERE geoidn = 0 I get a result for all the layers on 
the point (all the layers in fact).
Somehow this WHERE geoidn = 0 condition is constructed false. Ist should 
be something like WHERE geoidn = geoidNL.IMRO.0026.SVBBU-0001

I've not a clue where that wrong query clause comes from.

MArco
P.S. In earlier attempts I've renamed the tables with identical results.
