完美分页存储过程(有缺陷，无法加入条件)

使用分页存储过程  
    Create  PROCEDURE ListPage(  
    @tblName  nvarchar(200),           ----要显示的表或多个表的连接  
    @fldName  nvarchar(200) = '*',          ----要显示的字段列表  
    @pageSize int = 10,                    ----每页显示的记录个数  
    @page  int = 1,           ----要显示那一页的记录  
    @pageCount int = 1 output,          ----查询结果分页后的总页数  
    @Counts int = 1 output,           ----查询到的记录数  
    @fldSort nvarchar(100) = null,          ----排序字段列表或条件  
    @Sort  bit = 0,           ----排序方法，0为升序，1为降序  
    @strCondition nvarchar(200) = null, ----查询条件,不需where  
    @ID  nvarchar(50)  ----主表的主键  
    )  
    AS  
    SET NOCOUNT ON  
    Declare @sqlTmp nvarchar(1000)  ----存放动态生成的SQL语句  
    Declare @strTmp nvarchar(1000)  ----存放取得查询结果总数的查询语句  
    Declare @strID  nvarchar(1000)  ----存放取得查询开头或结尾ID的查询语句  
    Declare @sqlSort nvarchar(200)  ----存放临时生成的排序条件  
    Declare @intCounts int   ----要移动的记录数  
    Declare @BeginID int   ----开始的ID  
    Declare @EndID   int   ----结束的ID
