项目经验之:如CSDN一样的分页，我能否做这样的分页吗??????

分页大家都做过吧,分页最常见的如

有上下翻页,

有如百度一样翻页

还有如

还有如当当网一样的分页这个下次有机会再列出给大家(朋友给出的)

这篇文章讲到的一个分页,要做成论坛一样的分页格式,都用过CSDN吧,就是像CSDN上翻页样式相似

分页总的说来,大概分为Post分页与 URL 分页 ,举例来说吧,如大家在做GridView时自带的分页,其实其内含的就是 Post分页的 ,他分页本身URL地址是没有改变的.只是在回传

_doPostBack() 函数,

URL分页,相信大家也用过,静态页面的分页大部分用到的是URL分页,,, 还有就是文章的分页

说多了大家也觉得是多余的,还是看代码强些...........................................

注意我这段代码用到了codeproject网站上的一个组件 ASPnetPagerV2netfx2_0.dll 也是参考codeproject上面例子所做的我下面的例用到的数据库是 Northwind 数据库

SQL代码段

CREATE PROCEDURE sp_page
@CurrentPage int, @PageSize int,@Field_Info varchar(500),@Table_info varchar(20),@Field_id varchar(10),@intOrder int,@otherwhere varchar(50),@RecordCount int output,@PageCount int output
--@CurrentPage为显示那一页,@PageSize为每一页显示几行,@Field_info为要显示的字段可以为*,@Table_info为要查询的表或视图,@field_id为按这个字段排序,@intorder0为升序排1为降序排,@otherwhere为条件,@RecordCount为总行数,@PageCount为总页数
AS
begin
    DECLARE @MinPage int, @MaxPage int

    set @Table_info = replace(@table_info,'''','')       --除去@table_info中的'
    set @Field_id = replace(@Field_id,'''','')            --除去@field_id中的'
    set @otherwhere = replace(@otherwhere,'''','''''')     --将@otherwhere中的'换成''让SQL语句正确释别'
    set @sqlt = 'SELECT @RecordCount = COUNT(' + @Field_id + ') FROM ' + @Table_Info
    exec sp_executesql @sqlt,N'@RecordCount int output',@RecordCount output     --如何将exec执行结果放入变量中,如果是字符串就要用N,N后面的变量一定要和@sqlt里面的变量同名
    IF @PageSize <= 0
        begin
            set @PageSize = 10
        end
    else if @PageSize > @RecordCount
        begin
            set @pageSize = @RecordCount
        end
    set @pagecount = @RecordCount / @PageSize
    if ((@recordcount % @pagesize) != 0)                    --如果除不尽则加一页
        begin
            set @PageCount = @RecordCount / @PageSize
            set @PageCount = @pagecount + 1
        end
    else
        begin
            set @pagecount = @recordcount /@PageSize
        end
    IF @CurrentPage <= 0
        begin
            set @CurrentPage = 1
        end
    else if @CurrentPage > @pagecount
        begin
            set @currentpage = @pagecount        --如果输入页数大于总页数则符最后一页
        end
    SET @MinPage = (@CurrentPage - 1) * @PageSize + 1
    SET @MaxPage = @MinPage + @PageSize - 1

    BEGIN
        if @intorder = 0
            set @order = 'asc'
        else
            set @order = 'desc'
        if @Field_Info like ''
            set @field_Info = '*'
        if @otherwhere like ''
            set @sql = 'select ' + @Field_Info + ' from (select ' +  @Field_Info + ' , row_number() over(order by ' + @Field_id + ' ' + @Order + ') as rownumber from ' + @Table_info + ') as a where rownumber between ' + convert(varchar(10),@minpage) + ' and ' + convert(varchar(10),@maxpage)
        else
            set @sql = 'select ' + @Field_Info + ' from (select ' +  @Field_Info + ' , row_number() over(order by ' + @Field_id + ' ' + @Order + ') as rownumber from ' + @Table_info + ') as a where rownumber between ' + convert(varchar(10),@minpage) + ' and ' + convert(varchar(10),@maxpage) + ' and ' + @otherwhere
        exec(@sql)
