asp.net利用存储过程分页代码

下面是存储过程（sqlserver2000下通过)

--最通用的分页存储过程
--获取指定页的数据

CREATEPROCEDUREPagination

@tblNamevarchar(255),--表名

@strGetFieldsvarchar(1000)='*',--需要返回的列

@fldNamevarchar(255)='',--排序的字段名

@PageSizeint=10,--页尺寸

@PageIndexint=1,--页码

@doCountbit=0,--返回记录总数,非0值则返回

@OrderTypebit=0,--设置排序类型,非0值则降序

@strWherevarchar(1500)=''--查询条件(注意:不要加where)

AS

declare@strSQLvarchar(5000)--主语句

declare@strTmpvarchar(110)--临时变量

declare@strOrdervarchar(400)--排序类型



if@doCount!=0

begin

if@strWhere!=''

set@strSQL='selectcount(*)asTotalfrom['+@tblName+']where'+@strWhere

else

set@strSQL='selectcount(*)asTotalfrom['+@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='<(selectmin'

set@strOrder='orderby['+@fldName+']desc'

--如果@OrderType不是0，就执行降序，这句很重要！

end

else

begin

set@strTmp='>(selectmax'

set@strOrder='orderby['+@fldName+']asc'

end



if@PageIndex=1

begin

if@strWhere!=''

set@strSQL='selecttop'+str(@PageSize)+''+@strGetFields+'from['+@tblName+']where'+@strWhere+''+@strOrder

else

set@strSQL='selecttop'+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='selecttop'+str(@PageSize)+''+@strGetFields+'from['+@tblName+']where['+@fldName+']'+@strTmp+'(['+@fldName+'])
from(selecttop'+str((@PageIndex-1)*@PageSize)+'['+@fldName+']from['+@tblName+']'+@strOrder+')astblTmp)'+@strOrder



if@strWhere!=''

set@strSQL='selecttop'+str(@PageSize)+''+@strGetFields+'from['+@tblName+']where['+@fldName+']'+@strTmp+'(['+@fldName+'])from(selecttop'+str((@PageIndex-1)*@PageSize)+'['+@fldName+']
from['+@tblName+']where'+@strWhere+''+@strOrder+')astblTmp)and'+@strWhere+''+@strOrder

end

end

exec(@strSQL)
GO
