ODBC数据源连接Oracle数据库示例

配置ODBC数据源
1.选择“Microsoft ODBC for Oracle”

2.数据源名：连接字符串中的名字 ／ 用户名： 数据库名字（SID名）／服务器名：数据库服务器IP地址

using System.Data.Odbc;

private void MonitorBatch()
{
    string contection = "DSN=DSN_NAME;UID=USERNAME;Pwd=PASSWORD;"
    OdbcConnection conn = new OdbcConnection(contection);
    try
    {
        conn.Open();

        string sql = @"SELECT SEND_DATE, SEND_STS FROM MASTER WHERE SEND_DATE < to_char(sysdate,'yyyymmdd') AND SEND_STS = '0' AND ID < ? ORDER BY SEND_DATE ";

        OdbcCommand command = conn.CreateCommand();
        command.CommandText = sql;
        command.Parameters.Add("", OdbcType.Int).Value = 100;

        OdbcDataReader reader = command.ExecuteReader();
        if (reader.HasRows)
        {
            while (reader.Read())
            {
                Console.WriteLine(reader.GetString(0) + " " +reader.GetString(1));
            }
        }
        command.Dispose();
        reader.Close();
    }
    catch (Exception ex)
    {
Console.WriteLine(ex.Message)
    } finally {
        conn.Close();
    }
}
