asp.net中调用oracle存储过程的方法

CREATE OR REPLACE PROCEDURE gd_CURSOR(MYCS1 OUT SYS_REFCURSOR,MYCS2 OUT SYS_REFCURSOR,a out varchar)asBEGIN a:='test'; OPEN MYCS1 FOR SELECT 1 from dual; OPEN MYCS2 FOR SELECT 2 from dual;END;

 /// <summary> /// 执行oracle存储过程返回多个结果集 /// </summary> /// <param name="strProcName">存储过程名称</param> /// <param name="ResultCount">返回个数</param> /// <param name="paras">参数</param> /// <returns>任意对象数组</returns> public object[] ExcuteProc_N_Result(string strProcName, int ResultCount, params OracleParameter[] paras) {  using (OracleConnection conn = new OracleConnection("User ID=用户名;Password=密码;Data Source=数据库;"))  {  OracleCommand cmd = new OracleCommand(strProcName, conn);  if (paras != null && paras.Length > 0)  {   for (int j = 0; j < paras.Length; j++)   {   if (paras[j].Value == null)   {    paras[j].Value = DBNull.Value;   }   }  }  cmd.Parameters.AddRange(paras);  cmd.CommandType = CommandType.StoredProcedure;  conn.Open();  cmd.ExecuteNonQuery();  int i = 0;  //int nOutputParametersCount = 0;  object[] objResult = new object[ResultCount];  foreach (OracleParameter p in cmd.Parameters)  {   if (p.Direction == ParameterDirection.Output || p.Direction == ParameterDirection.InputOutput)   {   if (p.Value is OracleDataReader)   {    OracleDataReader reader = p.Value as OracleDataReader;    objResult[i++] = ConvertDataReaderToDataTable(reader);   }   else   {    objResult[i++] = p.Value;   }   }  }  return objResult;  } } /// <summary>  /// 将DataReader 转为 DataTable  /// </summary>  /// <param name="DataReader">OleDbDataReader</param>  protected DataTable ConvertDataReaderToDataTable(OracleDataReader reader) {  DataTable objDataTable = new DataTable("TmpDataTable");  try  {  int intFieldCount = reader.FieldCount;//获取当前行中的列数；  for (int intCounter = 0; intCounter <= intFieldCount - 1; intCounter++)  {   objDataTable.Columns.Add(reader.GetName(intCounter), reader.GetFieldType(intCounter));  }  //populate datatable   objDataTable.BeginLoadData();  //object[] objValues = new object[intFieldCount -1];   object[] objValues = new object[intFieldCount];  while (reader.Read())  {   reader.GetValues(objValues);   objDataTable.LoadDataRow(objValues, true);  }  reader.Close();  objDataTable.EndLoadData();  return objDataTable;  }  catch (Exception ex)  {  throw new Exception("转换出错出错!", ex);  } }

Create or Replace Procedure xx_yy( i_OrderID in number, i_ReturnValue out number)is v_RealValue number; v_TotalValue number; v_AdvendorID number;begin 自己写就行end;

create table ORDERTABLE( ORDERID NUMBER not null, TEXT NUMBER not null)

( i_OrderID in number, i_ReturnValue out number)is spass ordertable.text%type;begin select text into spass from ordertable where orderid=i_OrderID;  i_ReturnValue:=spass; exception when no_data_found then i_ReturnValue:=-1; end;

using System.Data .OracleClient ;//(别忘了添加)OracleConnection Oraclecon = new OracleConnection ("Password=dloco;User ID=dloco;Data Source=dloco;");  OracleCommand myCMD = new OracleCommand();  OracleParameter[] parameters = { new OracleParameter("i_OrderID", OracleType.Number, 10),new OracleParameter("i_ReturnValue",OracleType.Number,10 )};  parameters[0].Value = 1;  parameters[1].Direction = ParameterDirection.Output;  myCMD.Connection = Oraclecon;  myCMD.CommandType = CommandType.StoredProcedure;  myCMD.CommandText = "dloco.xx_yy";  myCMD.Parameters .Add (parameters[0]);  myCMD.Parameters .Add (parameters[1]);  myCMD.Connection.Open();    myCMD.ExecuteNonQuery();      string result=myCMD.Parameters["i_ReturnValue"].Value.ToString();  MessageBox.Show (result);  Oraclecon.Close();
