[mapserver-users] GetFeatureInfo using MySQL join - additional info

[Dejan Gambin]

Some additional info:

Since I need this data only for GetFeatureRequest, it seems like I should use JOIN within a LAYER object. So I did the following:

LAYER
...
  DATA "my"
  ...
  ...
  DUMP TRUE
  TEMPLATE "template.html"
  HEADER "template_header.html"
  FOOTER "template_footer.html"
  JOIN
    NAME "test"
    CONNECTION "MySQL:gis,host=localhost,user=gis,password=gis,tables=katastar_vodnjan"
#    CONNECTION "PG:host=localhost user=postgres password=runda711 dbname=vodnjan port=5432"     
    CONNECTIONTYPE ogr
    TABLE "katastar_vodnjan"
    FROM "KO_KC"
    TO "broj_ko_kc"
    TYPE ONE-TO-MANY
    TEMPLATE "template_join.html"
#	HEADER "template_header.html"
#	FOOTER "template_footer.html"    
  END  

I tried this with joined data from MySQL and from Postgres. No success. The interesting thing is, when I do:

shp2img -m my.map -o image.png -l "mylayer" -all_debug 3

I get:

[Tue Sep 13 08:58:04 2011].271467 msLoadMap(): 0.029s
[Tue Sep 13 08:58:04 2011].356888 msDrawMap(): Layer 0 (katastar_vodnjan_poligon), 0.083s

[Tue Sep 13 08:58:04 2011].402821 shp2img total time: 0.161s

Does anybody  know what is it? It happens for MySQL and Postgres database join

thanks very much
