存储过程分页显示的大大的问题
ALTER PROCEDURE sp_GetPriceInfo
(
@transCode char(2),
@pagesize int,
@pageindex int,
@docount bit
)
AS
begin
declare @sql nvarchar(500),@strsql nvarchar(4000)
set @sql= ' '
if(@transCode <> ' ')
begin
set @sql=@sql+ ' transCode=@transCode and '
end
if(@sql <> ' ')
set @sql= ' where ' +left(@sql,len(@sql)-4)
else
set @sql= ' '
set @strsql= 'if(@docount=1) '+
'SELECT count(*) FROM price '+@sql+
'else '+
'begin '+
'declare @indextable table(id int identity(1,1),nid int) '+
'declare @PageLowerBound int '+
'declare @PageUpperBound int '+
'set @PageLowerBound=(@pageindex-1)*@pagesize '+
'set @PageUpperBound=@PageLowerBound+@pagesize '+
'set rowcount @PageUpperBound '+
'insert into @indextable(nid) '+
'SELECT id FROM price '+@sql+
'SELECT * FROM price p '+
'inner join @indextable t on t.nid=p.id '+
'where t.id> @PageLowerBound and t.id <=@PageUpperBound order by p.endDate desc '+
' end '
exec sp_executesql @strsql,N '@transCode char(2),@pagesize int,@pageindex int,@docount bit ',@transCode,@pagesize,@pageindex,@docount
end
我现在有两个问题第一个问题就是数据的显示
在页面上 第一页只显示一条 第二页显示二条 依次类推
还有一个就是排序
这个order by p.endDate desc 是我的排序
它倒是实现了 但是之是在每一页里面进行排序 而不是对所有的数据总的来进行排序
高手看看我上面的存储过程是不是有问题
[解决办法]
-- 获取指定页的数据,网上摘录的
CREATE PROCEDURE pagination3
@tblName varchar(255), -- 表名
@strGetFields varchar(1000) = '* ', -- 需要返回的列
@fldName varchar(255)= ' ', -- 排序的字段名
@PageSize int = 10, -- 页尺寸
@PageIndex int = 1, -- 页码
@doCount bit = 0, -- 返回记录总数, 非 0 值则返回
@OrderType bit = 0, -- 设置排序类型, 非 0 值则降序
@strWhere varchar(1500) = ' ' -- 查询条件 (注意: 不要加 where)
AS
declare @strSQL varchar(5000) -- 主语句
declare @strTmp varchar(110) -- 临时变量
declare @strOrder varchar(400) -- 排序类型
if @doCount != 0
begin
if @strWhere != ' '
set @strSQL = "select count(*) as Total from [ " + @tblName + "] where "+@strWhere
else
set @strSQL = "select count(*) as Total from [ " + @tblName + "] "
end
--以上代码的意思是如果@doCount传递过来的不是0，就执行总数统计。以下的所有代码都是@doCount为0的情况
else
begin
if @OrderType != 0
begin
set @strTmp = " <(select min "
set @strOrder = " order by [ " + @fldName + "] desc "
--如果@OrderType不是0，就执行降序，这句很重要！
end
else
begin
set @strTmp = "> (select max "
set @strOrder = " order by [ " + @fldName + "] asc "
end
if @PageIndex = 1
begin
if @strWhere != ' '
set @strSQL = "select top " + str(@PageSize) + " "+@strGetFields+ " from [ " + @tblName + "] where " + @strWhere + " " + @strOrder
else
set @strSQL = "select top " + str(@PageSize) + " "+@strGetFields+ " from [ "+ @tblName + "] "+ @strOrder
--如果是第一页就执行以上代码，这样会加快执行速度
end
else
begin
--以下代码赋予了@strSQL以真正执行的SQL代码
set @strSQL = "select top " + str(@PageSize) + " "+@strGetFields+ " from [ "
+ @tblName + "] where [ " + @fldName + "] " + @strTmp + "([ "+ @fldName + "]) from (select top " + str((@PageIndex-1)*@PageSize) + " [ "+ @fldName + "] from [ " + @tblName + "] " + @strOrder + ") as tblTmp) "+ @strOrder
if @strWhere != ' '
set @strSQL = "select top " + str(@PageSize) + " "+@strGetFields+ " from [ "
+ @tblName + "] where [ " + @fldName + "] " + @strTmp + "([ "
+ @fldName + "]) from (select top " + str((@PageIndex-1)*@PageSize) + " [ "
+ @fldName + "] from [ " + @tblName + "] where " + @strWhere + " "
+ @strOrder + ") as tblTmp) and " + @strWhere + " " + @strOrder
end
end
exec (@strSQL)
