1,场景：根据学生编号查询，返回该学生所在班级的所有学生。支持分页、自定义排序及结果集自动定位到查询条件的学生编号所在页。

2,简单条件的,动态where语句(关于Like查询的动态where，建议使用笨办法做)

CREATE PROC [dbo].[Getstudentlistbycondition] @Name  NVARCHAR(20),
                                              @Class INT
AS
  SET nocount ON 
  BEGIN
      BEGIN
          SELECT [Name],
                 [class]
          FROM   [testtable]
          WHERE  [Class] = CASE
                             WHEN @Class > 0 THEN @Class ELSE [Class] END
                 AND [name] = CASE
                                WHEN @Name <> '' THEN @Name ELSE [Name] END
      END
  END
