Problem getting a LONG RAW value

Question

Hi,
I cannot make this code work:
OracleCommand cmd = new OracleCommand("ABC$MYPACKAGE.GetLogo", new OracleConnection(_constr));
cmd.CommandType = CommandType.StoredProcedure;
cmd.InitialLONGFetchSize = -1;
cmd.Connection.Open();
cmd.BindByName = true;
OracleParameter p = cmd.Parameters.Add("parameter_no1", OracleDbType.Decimal);
p.Value = 10549923;
p.Direction = ParameterDirection.Input;
p = cmd.Parameters.Add("parameter_no2", OracleDbType.Decimal);
p.Value = 656427;
p.Direction = ParameterDirection.Input;
p = cmd.Parameters.Add("RETCURSOR", OracleDbType.RefCursor);
p.Direction = ParameterDirection.Output;
OracleDataReader reader = cmd.ExecuteReader();
if (reader.Read())
... code here ...
cmd.Connection.Close();
It keeps throwing AccessViolationException when executing the reader.Read() statement.
The only value the ref cursor returns is a LONG RAW, but it fails even before I try to access that through the reader. I cant seem to find the problem!
regards,
Carl

Answer 1

Can you try out changing ExecuteReader to ExecuteNonQuery and get OracleDataReader from the OracleRefCursor stored in p.Value?
Something like -
cmd.ExecuteNonQuery();
OracleRefCursor cur = p.Value;
OracleDataReader reader = cur.GetDataReader();
