刚入公司,只能从头学,没有办法.这里暂时变成我的笔记吧
using System.Data;
using System.Data.OracleClient;
......
private void button_Click(object sender, System.EventArgs e)
{
string ConnectionString="Data Source=SID_Name;user=Your_UserID;password=Your_password;";//写连接串
OracleConnection conn=new OracleConnection(ConnectionString);//创建一个新连接
try
{
conn.Open();
OracleCommand cmd=conn.CreateCommand();
cmd.CommandText="select * from MyTable";//在这儿写sql语句
OracleDataReader odr=cmd.ExecuteReader();//创建一个OracleDateReader对象
while(odr.Read())//读取数据，如果odr.Read()返回为false的话，就说明到记录集的尾部了
{
this.label.Text=odr.GetString(0).ToString();
}
odr.Close();
}
catch (OracleException ee)
{
string errorMessage = "Code: " + ee.Code + "\n" +
"Message: " + ee.Message;
Console.WriteLine("\t{0}", errorMessage);
}
finally
{
conn.Close(); //关闭连接
}
}
