  public DataSet sreetest(DataTable dt)
        {
            DataSet dsRegularIndentdtl = new DataSet();
            try
            {
                OracleConnection OraConn = new OracleConnection(strDBConnection);
                OraConn.Open();

                OracleCommand OraCmd = new OracleCommand();
                OraCmd.Connection = OraConn;
                OraCmd.CommandText = "PR_SREE_TEST";
                OraCmd.CommandType = CommandType.StoredProcedure;
                OracleParameter parameter = new OracleParameter();


                var recordSet1 = new DataTable();
                recordSet1 = dt;
               OraCmd.Parameters.Add("p_recordset", OracleDbType.RefCursor, recordSet1, ParameterDirection.Input);
                 OraCmd.ExecuteNonQuery();
            }
            catch (Exception ex)
            {
                throw ex;
            }
            return dsRegularIndentdtl;
        }
    }

above is my code it is saying that p_recordset not valied. please tell me how to execute it.

回答1:

Make sure you are using the correct overload of OraCmd.Parameters.Add(),

As per msdn the fourth parameter is not parameter direction, it is as below

public OracleParameter Add(
    string parameterName,
    OracleType dataType,
    int size,
    string srcColumn
)
