[mapserver-users] Using the SQL Server 2008 Plugin with a

To clarify I have a column in SQL 2008 of type geography that I would like to use in map server. I have been able to do this using the OGR ODBC driver. However, when trying to use the Native SQL 2008 driver that has been added to MS4W 2.3.1 I get the error message "sys.geometry is incompatible with sys.geography" when executing the query captured by profiling the database request.
It appears as though the SQL 2008 driver either assumes that it will always (and only) be used against geometry columns or there is a configuration setting I that I can use to tell it that the internal datatype is geography and as such builds the WHERE clause using the geomertry type for the bounding box filter.
the_geom.STIntersects(Geometry::STGeomFromText('POLYGON(...)') = 1
where in this case the_geom is a Geography column that cannot be used in an STIntersects call with a Geometry object.
I am hoping someone can tell me about the configuration option to change this behavior or confirm that it does not exist so we can discuss the possibility of adding such an option.
Let me know if you need additional details.
There are two ways to define an object spatially in 2008 one as type geometry and one as geography.
