If you look at the GetCapabilities of the SDF provider, you will see that it supports the following spatial operators:

 Contains
 Disjoint
 Intersects
 Within
 Inside
 EnvelopeIntersects

So, there is no support for "Touches" with the SDF provider. Can you use the "Intersects" instead?

Hi,

i want to use the spatial query Touches but, i have this Error : Operation
spatiale FDO non prise en charge. so it says that i can't use this query, is
it a known issue ?

my code :

queryOptions2.SetSpatialFilter(layerObj.GetFeatureGeometryName(),geometry,MgFeatureSpatialOperations.Touches);

i use mapguide open source 1.2 rc2 with SDF files

thanks
