[ka-Map-users] query in ka-map with mapserver

[王连波]

Hi all,
I am really anxious about ka-map query and search now. In my mapfile I
configured a layer as follows and it displayed a city's boundary constituted
of 68 lines. Then I think it is valid to select some of the lines and get
their id from the table where the_geo DATA is stored in my database.
However, when I finished the query just get "no matching results". I have
read the script file "map_query_float.php" and found nothing special. Should
I configure the mapfile to tell ka-map which table in postgis is going to be
looked for? If so, how? If not, why I can not get what I want ? Thank you
for any clues.
