下面的代码在SQL2008能能分页，Select * From
(
Select ROW_NUMBER() OVER (order by {3}) as 'RowNumber',OrgNo,OperatorNo,Name,Tel,Address,OnJob,MaxCutM,password,OperatorType,Re FROM Operator where 1=1 {0}
)temp
where temp.RowNumber between {1} and {2}SQL2000没有的ROW_NUMBER()怎么实现分页 能给出上面的等同代码？

其实top是优于row_number的SELECT TOP 10 * FROM tb WHERE id>( SELECT ISNULL(max(id),0) FROM (SELECT TOP 20 idFROM tb ORDER BY id) t )

List<SqlParameter> lstParas = new List<SqlParameter>();

}

sbSql.Append(sCountSql);
DataSet ds = DbHelperSQL.Query(sbSql.ToString(), lstParas);

}里面用的都是参数 。能结合这个方法写出来是最好了。谢谢
2005或是2008可以用row_number()
但是top不能用参数吧楼主要求能够适用他的方法的话，还是新建id插入临时表传参来处理比较好declare @page int
declare @row int
set @row=2
set @page=3select * from #t where id between @row*(@page-1)+1 and @row*@page
order by value
记录多了，双top的效率会很低吧
对于表中主键或标识列的情况,直接从原表取数查询，其它情况使用临时表的方法
如果视图或查询结果中有主键,不推荐此方法--邹建 2003.09(引用请保留此信息)--*//*--调用示例
exec p_show '地区资料' exec p_show '地区资料',5,3,'地区编号,地区名称,助记码','地区编号'
