Undefined type causing C# error

I think you are right, but just need to know how to define the SDO_GEOMETRY in the web.config.

public GetTables(string table_name, string connString, out BaseCommand procedure)
        {
            procedure = new BaseCommand();
            procedure.ConnectionStr = connString;
            procedure.Cmd = new OracleCommand("MY_PKG.GET_TABLE");
            procedure.Cmd.CommandType = System.Data.CommandType.StoredProcedure;
            OracleParameter pTableName = procedure.Cmd.Parameters.Add("pTableName", OracleDbType.Varchar2, ParameterDirection.Input);
            OracleParameter RESULT_SET = procedure.Cmd.Parameters.Add("RESULT_SET", OracleDbType.RefCursor, ParameterDirection.Output);

            pTableName.Value = table_name;

           
        }

The out parameter is a Command that I am then executing as a datareader into a datatable:


 public DataTable GetDt(BaseCommand com)
        {
            using (OracleConnection connection = new OracleConnection(com.ConnectionStr))
            {
                using (OracleCommand command = com.Cmd)
                {
                    try
                    {
                        command.Connection = connection;
                        connection.Open();
                        using (OracleDataReader r = command.ExecuteReader())
                        {
                            DataTable dt = new DataTable();
                            dataTable.Load(r);
                            connection.Close();
                            return dt;
                        }

                    }
                    catch (OracleException oe)
                    {
                        throw new Exception(oe.Message);
                    }
                    catch (Exception e)
                    {
                        throw new Exception(e.Message);
                    }

                }

Can you look at the GET_TABLE stored procedure in the MY_PKG package?  Does it reference SDO_GEOMETRY?

Yes and it is not in any way referencing SDO_Geometry although the table being referenced does have an SDO_Geometry column.

I am doing a specific selection not a select *.

Found the issue, another selection within the procedure does have a geometry column.
Sorry for the inconvenience.

I am learning about how .NET and Oracle work together with UDTs, and I am curious how you get this issue solved.

I know when using the entity framework as an ORM you must define UDT's in the config file.
SDO_Geometry though is an Oracle complex type so I found a package that supposedly deals with it, called NetSdoGeom. I just could not believe I needed that without directly selecting that field. Little did I know another table in the procedure had a Geom column which was the culprit.

Found the link to the package: http://code.google.com/p/tf-net/downloads/detail?name=NetSdoGeometry.zip&can=2&q=

Cool!!  That is what I use (INullable, IOracleCustomType, IOracleCustomTypeFactory, ...) to work with Oracle Custom objects.  I don't have to do anything in the config files, because it is just a parameter value to a package procedure:

       

    OracleParameter parameter = new OracleParameter()
            {
                ParameterName = parameterName,
                OracleDbType = OracleDbType.Object,
                Direction = ParameterDirection.Input,
                UdtTypeName = customTypeAttribute.UdtTypeName,
                Value = this.CreateTable<TFactory, TTable, TRecord>(recordArray),
            };

Select all Open in new window

And this works with SDO_Geometry?

No, that works with the UDT that I work with.  I haven't tried to access the spatial geometry stuff yet, so this is a good question to learn something that might be useful for the future.
