oracle 存储过程返回结果集 table形式的案例(2)-木庄网络博客

1.首先建立一个包

create or replace package LogOperation is
 type listLog is ref cursor;
 procedure PCenterExamine_sel(listCenterExamine out listlog,testlist out listLog,numpage in decimal);
end;

2.建立包中的主体

create or replace package body LogOperation is
 procedure PCenterExamine_sel
 (
  listCenterExamine out listlog,
  testlist out listlog,
  numpage in decimal
 ) 
 as
 begin
  open listCenterExamine for select * from Log_CenterExamine;
  open testlist for select * from Log_CenterExamine;
 end;
end;

3.在程序中调用存储过程的值

public static DataSet RunProcedureGetDataSet(string storedProcName, OracleParameter[] parameters)
    {
      string connectionString ="192.168.1.1/db";
      using (OracleConnection connection = new OracleConnection(connectionString))
      {
        DataSet dataSet = new DataSet();
        connection.Open();
        OracleDataAdapter sqlDA = new OracleDataAdapter();
        sqlDA.SelectCommand = BuildQueryCommand(connection, storedProcName, parameters);
        sqlDA.Fill(dataSet, "dt");
        connection.Close();
        return dataSet;
      }
    }

private static OracleCommand BuildQueryCommand(OracleConnection connection, string storedProcName, IDataParameter[] parameters)
    {
      OracleCommand command = new OracleCommand(storedProcName, connection);
      command.CommandType = CommandType.StoredProcedure;
      foreach (OracleParameter parameter in parameters)
      {
        command.Parameters.Add(parameter);
      }
      return command;
    }

4.有几个out的ref cursor，变量ds中就用几个DataTable。并且输入参数 indecimal也不会受影响，并且可以参加存储过程的运算

OracleParameter[] paramDic = { 
          new OracleParameter("listCenterExamine",OracleType.Cursor),
          new OracleParameter("testlist",OracleType.Cursor),
          new OracleParameter("numpage",OracleType.Int32)};
        paramDic[0].Direction = ParameterDirection.Output;
        paramDic[1].Direction = ParameterDirection.Output;
        paramDic[2].Value = 1;
        ds = Model.OracleHelper.RunProcedureGetDataSet("LogOperation.PCenterExamine_sel", paramDic);

以上为个人经验，希望能给大家一个参考，也希望大家多多支持。如有错误或未考虑完全的地方，望不吝赐教。
