Hi,

I have a problem executing an ExecuteArray command on a table with a field of type LONGRAW

The following works fine

Code: Select all


            string sql = "Insert into FL_KATEGORIENBILDER values (:1, :2)";

                // write single line
                long param1 = 4;
                byte[] param2 = new byte[3] { 100, 101, 102 };

                List parameter = new List();
                parameter.Add(new OracleParameter("1", OracleDbType.Number, param1, ParameterDirection.Input));
                parameter.Add(new OracleParameter("2", OracleDbType.LongRaw, param2, ParameterDirection.Input));

                OracleCommand command = new OracleCommand(sql);
                command.Parameters.Add(parameter);

                command.ExecuteNonQuery();

When I try the same with an ExecuteArray

Code: Select all

                // write array with two lines
                long[] param3 = new long[2] { 5, 6 };
                byte[][] param4 = new byte[2][] { new byte[3] { 100, 101, 102 }, new byte[3] { 100, 101, 102 } };

                parameter = new List();
                parameter.Add(new OracleParameter("1", OracleDbType.Number, param3, ParameterDirection.Input));
                parameter.Add(new OracleParameter("2", OracleDbType.LongRaw, param4, ParameterDirection.Input));

                command = new OracleCommand(sql);
                command.Parameters.Add(parameter);

                command.ExecuteArray(2);

I get the following error

Eine Ausnahme (erste Chance) des Typs "System.InvalidCastException" ist in Devart.Data.dll aufgetreten.

Can you give me any hint what's going wrong?

We have fixed the bug with the OracleCommand.ExecuteArray method when one of parameters has type equal to LONG or LONG RAW. We will notify you when the corresponding build of dotConnect for Oracle is available for download.
