Spatial types as parameters to SQLCommand objects RRS feed

  • General discussion

  • I saw on Bob's blog that some parameter items are going to be fixed in .net 4.0

    I noticed that if trying to pass parameters from C# to a stored proc using SqlCommandBuilder.DeriveParameters any parameters for Geography (probably Geometry as well) do not get assigned a known UdtTypeName.  The parameters are thought to be of type varbinary. 

    The workaround is to explicity set UdtTypeName like this
    _cmd.Parameters["@Geog"].UdtTypeName = "GEOGRAPHY";

    It would be great if this were also fixed in .net 4.  If anyone has the environment to verify this, please post your findings.
