PetaPoco使用

    <add name="connectionStringName" connectionString="server=localhost;database=0914;uid=sa;password=850414;" />

            Console.Read();
        }
    }
}

注意:
  这里的分页执行的语句是:

SELECT * FROM 
(SELECT ROW_NUMBER() OVER (ORDER BY Degree DESC) peta_rn, * FROM Achievement WHERE Course=N'C#程序设计') peta_paged 
WHERE peta_rn>0 AND peta_rn<=3
