I have a gpkg file. I trying to open it with
spatial_lite gui and cast geometry to GML.
select AsGML(geom) from MyTable
but i got
null. I tried another functions
AsText(), AsWKT(), st_asText()... but anyway i got null. BTW function ST_GeometryType(geom) returns
LINESTRING, but other functions don't work.
My final goal is to cast geometry from gpkg to GML on c#. But it's looks impossible because I cannot even select geometry in
Do I use wrong queries? What can be wrong here?
