Question

我正在做一个MVC应用程序。我正在使用带有Enterprise Library连接的Oracle数据库。

我遇到的问题是在使用ExecuteSprocAccessor ...

时检索数据

当我使用Linq绑定返回的数据时，它工作正常。但是当我ExecuteSprocAccessor收到错误时..... The number of parameters does not match number of values for stored procedure

＆＃13;

Database db = readConfig.ReadWebConfig();
                string SP_NAME = "PKG_AR_PRESUPUESTOS_HS.GET_CAMPANAS";
                
                using (DbCommand dbCommand = db.GetStoredProcCommand(SP_NAME))
                {

                    dbCommand.Parameters.Clear();
                    db.AddInParameter(dbCommand, "p_COD_PAIS", DbType.Int32, 32);
                    db.AddInParameter(dbCommand, "p_COD_COMPANIA", DbType.Int32, 36);
                    db.AddInParameter(dbCommand, "p_COD_MEDIO", DbType.Int32, 4);
                    db.AddInParameter(dbCommand, "p_COD_CLIENTE", DbType.Int32, 285);
                    OracleParameter oraPara1 = new OracleParameter("CURSORSALIDA", OracleType.Cursor);
                    oraPara1.Direction = ParameterDirection.Output;
                    dbCommand.Parameters.Add(oraPara1);
                    
                      List<Campana> result2 = db.ExecuteDataSet(dbCommand).Tables[0].AsEnumerable().ToList().ConvertAll(dr => new Campana
                    {
                        COD_CAMPANA = Convert.ToInt32(dr["COD_CAMPANA"].ToString()),
                        COD_COMPANIA = Convert.ToInt32(dr["COD_COMPANIA"].ToString()),
                        COD_PRODUCTO = Convert.ToInt32(dr["COD_PRODUCTO"].ToString()),
                        DES_CAMPANA = dr["DES_CAMPANA"].ToString()
                    });

＆＃13;

这项工作很好......

但是当我使用

时

＆＃13;

Database db = readConfig.ReadWebConfig();
                string SP_NAME = "PKG_AR_PRESUPUESTOS_HS.GET_CAMPANAS";
                
                using (DbCommand dbCommand = db.GetStoredProcCommand(SP_NAME))
                {

                    dbCommand.Parameters.Clear();
                    db.AddInParameter(dbCommand, "p_COD_PAIS", DbType.Int32, 32);
                    db.AddInParameter(dbCommand, "p_COD_COMPANIA", DbType.Int32, 36);
                    db.AddInParameter(dbCommand, "p_COD_MEDIO", DbType.Int32, 4);
                    db.AddInParameter(dbCommand, "p_COD_CLIENTE", DbType.Int32, 285);
                    OracleParameter oraPara1 = new OracleParameter("CURSORSALIDA", OracleType.Cursor);
                    oraPara1.Direction = ParameterDirection.Output;
                    dbCommand.Parameters.Add(oraPara1);
                    
 List<Campana> result = db.ExecuteSprocAccessor<Campana>(SP_NAME,  dbCommand.Parameters).ToList<Campana>();

＆＃13;

收到错误... The number of parameters does not match number of values for stored procedure

即使我使用Mapping

＆＃13;

                    IRowMapper<Campana> resmapper = MapBuilder<Campana>.MapAllProperties()
                                                  .Map(x => x.COD_CAMPANA).ToColumn("COD_CAMPANA")
                                                  .Map(x => x.COD_COMPANIA).ToColumn("COD_COMPANIA")
                                                  .Map(x => x.DES_CAMPANA).ToColumn("DES_CAMPANA")
                                                  .Map(x => x.COD_PRODUCTO).ToColumn("COD_PRODUCTO")
                                                  .Build();
                    DataTable dt = db.ExecuteDataSet(dbCommand).Tables[0];
                    
   List<Campana> result = db.ExecuteSprocAccessor<Campana>(SP_NAME, resmapper, dbCommand.Parameters).ToList<Campana>();

＆＃13;

我得到了同样的错误......

ExecuteSprocAccessor有什么问题？

无论如何，我的Campana课程看起来像这样。

＆＃13;

  public class Campana
    {
        public Int32  COD_COMPANIA { get; set; }
        public Int32 COD_CAMPANA { get; set; }
        public string DES_CAMPANA { get; set; }
        public Int32 COD_PRODUCTO { get; set; }
    }

Answer 1

我解决了它传递一个对象[]而不是cmd.Parameters

＆＃13;

object[] param = ParametertoObj(dbCommand);
List<Campana> result = db.ExecuteSprocAccessor<Campana>(SP_NAME, resmapper, param).ToList<Campana>();

＆＃13;

和我创建数组的类

＆＃13;

 public object[] ParametertoObj(DbCommand cmd)
            {
                object[] obj = new object[cmd.Parameters.Count];
                int i = 0;
                foreach (DbParameter item in cmd.Parameters)
                {
                    obj[i] = item.Value;
                    i++;
                }
                return obj;
            }
