[mapserver-users] GetFeatureInfo using MySQL join

[Dejan Gambin]

Hi,

After solving my compile problem (thanks to thomas), I need to do GetFeatureInfo to a shape layer joined to MySQL table (non-spatial join).

I compiled MapServer with MySQL support and everything seems ok, but "mapserv -v" doesn't return "INPUT=MYSQL". Is it supposed to anyway? Or it is enough to be compiled with gdal/ogr that supports MySQL?

Because - when I do this:

ogrinfo -sql "SELECT * FROM my LEFT JOIN 'MYSQL:gis,host=localhost,user=gis,password=gis'.katastar_vodnjan ON my.KO_KC=katastar_vodnjan.broj_ko_kc" /var/www/data/vodnjan/my.shp

I get all the attributes from shape (dbf) and MySQL, so everything seems fine

But using thi:

LAYER # katastar vodnjan poligoni
  NAME "mylayer"
  STATUS ON
  CONNECTIONTYPE ogr  
  CONNECTION "/var/www/data/vodnjan/my.shp"
  DATA "SELECT * FROM my LEFT JOIN 'MYSQL:gis,host=localhost,user=gis,password=gis'.katastar_vodnjan ON my.KO_KC=katastar_vodnjan.broj_ko_kc"
  TYPE POLYGON  
...

I don't get any information with GetFeatureInfo. The request is like:

http://www.coin.hr/cgi-bin/mywms61?SERVICE=WMS&VERSION=1.1.1&REQUEST=GetFeatureInfo&BBOX=5403800,4981350,5403980,4981460&SRS=EPSG:31275&WIDTH=400&HEIGHT=300&LAYERS=katastar_vodnjan_poligon&STYLES=&FORMAT=image/png&TRANSPARENT=true&QUERY_LAYERS=mylayer&INFO_FORMAT=gml&X=200&Y=100

Using the same request with regular mapfile:

LAYER # katastar vodnjan poligoni
  NAME "mylayer"
  STATUS ON
  DATA "my"
  TYPE POLYGON  
...

returns one feature and its attributes from the dbf (tha is OK)

I have also tried with JOIN clause in LAYER part, but this doesn't work either. Do I have to use owf? Am I doing something wrong?

regards, dejan
