1.  數據綁定：
    (1) 綁定到DataGrid(WebApp)

if(emps.LoadAll())
...{
     dvEmps = emps.DefaultView;
     dgEmps.DataSource = dvEmps;
     dgEmps.DataBind();
}

   (2) 綁定到ComboBox(WinApp)

//get data
emps.Query.AddResultColumn(Employees.ColumnNames.EmployeeID);
emps.Query.AddResultColumn(Employees.ColumnNames.LastName);
emps.Query.AddOrderBy(Employees.ColumnNames.LastName,
WhereParameter.Dir.ASC);
emps.Query.Load();
//bind to combobox
cmbEmployees.DisplayMember = Employees.ColumnNames.LastName;
cmbEmployees.ValueMember = Employees.ColumnNames.EmployeeID;
cmbEmployees.Datasource = emps.DefaultView;

   (3) 綁定到DropDownList(WebApp)

 //get data
 emps.Query.AddResultColumn(Employees.ColumnNames.EmployeeID);
 emps.Query.AddResultColumn(Employees.ColumnNames.LastName);
 emps.Query.AddOrderBy(Employees.ColumnNames.LastName,
 WhereParameter.Dir.ASC);
 emps.Query.Load();
 //bind to drop-down list
 ddlEmployees.Datasource = emps.DefaultView;
 ddlEmployees.DataTextField = Employees.ColumnNames.LastName;
 ddlEmployees.DataValueField = Employees.ColumnNames.EmployeeID;
 ddlEmployees.Databind();

2.  特殊函數：執行自定義存儲過程和SQL語句

Examples:
（1）LoadFromSql: (從數據庫中檢索并返回檢索結果集,查詢結果保存到DataTable中)

ListDictionary Parms = new ListDictionary();
Parms.Add("@parameterName1", value1);
Parms.Add("@parameterName2", value2);
parms.Add……
if(this.LoadFromSql("proc_GetSpecialEmployee", Parms))
...{
  ...
}

（2）LoadFromSqlNoExec: (執行無結果集的存儲過程，返回受影響的行數)
        int NbrOfChecks = this.LoadFromSqlNoExec("proc_CalculatePayroll");
        例如：刪除一條記錄，dOOdad提供的文檔中的方法是：先LoadByPrimaryKey,再MarkAsDeleted,最后再Save進數據庫；這個過程要對數據庫進行兩次操作。實際上，我們可以只操作一次數據庫(直接用dOOdads模板生成的存儲過程)，而不用先Load。
 ListDictionary Parms = new ListDictionary();
 Parms.Add("@ID", empID);
 int effectLine = this.LoadFromSqlNoExec("proc_EmployeeDelete",Parms);

（3）LoadFromSqlReader:(返回SqlDataReader)
 SqlDataReader rdr = this.LoadFromSqlReader("proc_GetSpecialEmployee", Parms) as SqlDataReader;

（4）LoadFromSqlScalar:(返回單個值)
 DateTime EarliestHireDate;
 ListDictionary Parms = new ListDictionary();
 Parms.Add("@Active", 1);
 EarliestHireDate = Convert.ToDateTime(this.LoadFromSqlScalar("GetEarliestHireDate",Parms));

（5）LoadFromRawSql:
 this.LoadFromRawSql("SELECT MIN(EM_HireDate) FROM tEmployees WHERE EM_Active = {0}","1");

3.  事務處理:

TransactionMgr tx = TransactionMgr.ThreadTransactionMgr();
try
...{
    Employees emps = new Employees();
    emps.AddNew();
    emps.FirstName = "Jimmy";
    emps.LastName = "Doe";
    Products prds = new Products();
    prds.AddNew();
    prds.ProductName = " Lunch Box ";
    prds.Discontinued = false;
    tx.BeginTransaction();
    emps.Save();
    prds.Save();
    tx.CommitTransaction();
}
catch(Exception ex)
...{
    tx.RollbackTransaction();
    TransactionMgr.ThreadTransactionMgrReset();
}
