var Sql = factorySql.Create<Users, InformationCategories>();
//简单查询,返回实体类列表。
var sdfsf123 = Sql.ExecuteList<Users>((a, b) =>

//分页查询,返回表
DataTable dtUser = Sql.ExecuteDataTable((a, b) =>

//多表查询

//居然还可以 同时执行同个语句。
var sdfsf1113 = Sql.ExecuteList<Users>((a, b) =>
Sub.Insert(a).Values( "213" , "111" , 11, "2012-02-02" ).
Next().

);
//数据库需要的都有,还有union,还有事务。大大缩短了我的开发时间。下面是插入,更新,删除。查询速度非常快。目前只支持sql server,听说oracle也快支持了哦。
//插入
Sql.ExecuteNonQuery((a) =>
Sub.Insert(a).Fields(a.UserName, a.RoleId, a.LoginPassword, a.CreateDate).Values( "Jane" , 11, "213" , DateTime.Now)
);
//更新
var sdfsf6 = Sql.ExecuteNonQuery((a) =>
Sub.Update(a).Set(a.UserName == "1" ).From(a).Where(a.UserId == irod)
);
//删除
var sdfsf2 = Sql.ExecuteNonQuery((a, b) =>
Sub.Delete(a).From(a) .Where(a.UserId == 1)
);
