Yes, you can. For example you can use the following code in your asp.net project:

Code: Select all

            OracleConnection conn = new OracleConnection("host=***;port=1521;user id=***;password=***;sid=orcl1120;direct=true;");
            conn.Open();
            OracleCommand comm = new OracleCommand("P_Query", conn);
            comm.CommandType = System.Data.CommandType.StoredProcedure;
            OracleTable table = new OracleTable(OracleType.GetObjectType("T_Sale_Type",conn));
            table.Add("hi");
            table.Add("Ok");
            comm.Parameters.Add("table", OracleDbType.Table).Value = table;
            comm.ExecuteNonQuery();
            conn.Close();

Yes, the snippet of code will work only with the latest version of dotConnect for Oracle (6.70.293), because the support for OBJECT, TABLE, VARRAY, REF, XMLTYPE data types in Direct mode was added in this version. For more information please refer to http://www.devart.com/dotconnect/oracle ... story.html
You can upgrade to the latest version or refuse to use direct mode. You can also download the Trial Edition of dotConnect for Oracle at http://www.devart.com/dotconnect/oracle/download.html and evaluate new features.
