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 spatial_lite gui
.
Do I use wrong queries? What can be wrong here?
