c# - ORA-00900:用数据集填充DataAdapter时，SQL语句无效。 C#ASP.net

我正在使用VS'12 ASP.net 4.5和oracle 10.2.0.1

这是我的代码中出现异常的地方。

Agreement agreement = null;

            using (OracleConnection MyConn = new BaseRepository().GetConnection())
            {

                MyConn.Open();
                OracleCommand commOracle = new OracleCommand("PACKAGE_AGREEMENT.USP_GET_AGREEMENT_BY_ID", MyConn);


                VendorRepository vendorRepository = new VendorRepository();

                commOracle.Parameters.Add("SP_AGREEMENT_ID", OracleDbType.Int32, Agreementid, System.Data.ParameterDirection.Input);
                commOracle.Parameters.Add("SP_CUR_AGREEMENT", OracleDbType.RefCursor, ParameterDirection.Output);

                OracleDataAdapter daOracle = new OracleDataAdapter(commOracle);
                DataSet dsOracle = new DataSet();

                daOracle.Fill(dsOracle);//Here the exception arises.


                if (dsOracle.Tables[0].Rows[0] != null)
                {
                    DataRow row = dsOracle.Tables[0].Rows[0];
                    agreement = new Agreement();

                    agreement.pkAgreementId = Convert.ToInt32(row["pkAgreementId"]);
                    agreement.Vendor = vendorRepository.GetById(Convert.ToInt32(row["fkVendorId"]));
                    agreement.IsActive = row["IsActive"].ToString() == "N" ? false : true;
                    agreement.IsDeleted = row["IsDeleted"].ToString() == "N" ? false : true;
                    agreement.RentalAmount = Convert.ToInt32(row["RentalAmount"]);
                    agreement.VehicleCost = Convert.ToInt32(row["VehicleCost"]);
                    agreement.DateOfAgreement = Convert.ToDateTime(row["DateOfAgreement"]);
                    agreement.DateCreated = Convert.ToDateTime(row["DateCreated"]);
                    agreement.DateModified = Convert.ToDateTime(row["DateModified"]);

                }
            }

我的软件包PACKAGE_AGREEMNET规范：

create or replace PACKAGE PACKAGE_AGREEMENT AS TYPE REF_CURSOR IS REF CURSOR; PROCEDURE USP_GET_AGREEMENT_BY_ID(SP_AGREEMENT_ID IN NUMBER, SP_CUR_AGREEMENT OUT REF_CURSOR);  END PACKAGE_AGREEMENT;

包装主体：

create or replace PACKAGE BODY PACKAGE_AGREEMENT AS PROCEDURE USP_GET_AGREEMENT_BY_ID(SP_AGREEMENT_ID IN NUMBER, SP_CUR_AGREEMENT OUT REF_CURSOR) IS BEGIN OPEN SP_CUR_AGREEMENT FOR SELECT "Agreement".*, ora_rowscn as TimeStamp FROM "Agreement" WHERE "pkAgreementId" = SP_AGREEMENT_ID AND "IsDeleted" = 'N'; END USP_GET_AGREEMENT_BY_ID; END PACKAGE_AGREEMENT;

现在，如果我在Visual Studio中运行程序包（数据连接）。它编译没有错误，也没有警告。我不知道问题出在哪里。

请帮忙。

提前致谢。

最佳答案

您是否在执行命令之前先设置了命令类型？
