C# 不检索数据

9，不检索数据

代码：
 
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Data;              //注意
using System.Data.OracleClient; //Oracle数据库

namespace ConsoleApplication4
{
    class Program
    {
        static void Main(string[] args)
        {

            OracleConnection thisConnection = new OracleConnection(@"Data Source=orcl;User ID=shibei;Password=nsic;Unicode=True");

            thisConnection.Open();//此处可以不用打开    

            OracleCommand thisCommand = thisConnection.CreateCommand();

            thisCommand.CommandText = "update N_AIT set NAME = '改你了，怎么地' where ID = 34251";

            int rows = 0;
            try
            {

                rows = thisCommand.ExecuteNonQuery();//返回行数

                //取出返回值
                Console.WriteLine(Convert.ToString(rows));
            }
            catch (Exception er)
            {
                string merr = "err:" + er.ToString();
                Console.WriteLine(merr);
            }
            finally
            {
                thisConnection.Close();
                thisConnection.Dispose();//释放所有资源
                thisCommand.Parameters.Clear();
                thisCommand.Dispose();//释放所有资源
            }
        }
    }
}

运行结果：

注意：此方法对删除和插入同样有效哦
