Question

我能够检索数据库值并插入数据库值，但我无法弄清楚where语句应该是什么Update（）语法。

环境 - ＆gt; ASP.Net，C＃

Settings.ttinclude

    const string Namespace = "subsonic_db.Data";
    const string ConnectionStringName = "subsonic_dbConnectionString";

    //This is the name of your database and is used in naming
    //the repository. By default we set it to the connection string name
    const string DatabaseName = "subsonic_db";

Retreive示例

var product = equipment.SingleOrDefault(x => x.id == 1);

插入示例

   equipment my_equipment = new equipment();

    try
    {
        // insert
        my_equipment.parent_id = 0;
        my_equipment.primary_id = 0;
        my_equipment.product_code = product_code.Text;
        my_equipment.product_description = product_description.Text;
        my_equipment.product_type_id = Convert.ToInt32(product_type_id.SelectedItem.Value);
        my_equipment.created_date = DateTime.Now;
        my_equipment.serial_number = serial_number.Text;

        my_equipment.Save();

    }
    catch (Exception err)
    {
        lblError.Text = err.Message;
    }

编辑：认为我昨晚太累了，更新很容易。只需使用检索功能并使用更新（）。

    var equip = Equipment.SingleOrDefault(x => x.id == 1);

    lblGeneral.Text = equip.product_description;

    equip.product_description = "Test";
    equip.Update();
