请教ASP与存储过程问题
正常T-SQL语句select   *   from   table   order   by   code   asc(数据在万条以上   SQLSERVER2000)
问题1:如何使用存储过程输出查找结果  
问题2:如何实现分页功能
问题3:   存储过程真的要比普通的SQL语句站用资源小吗   还是已经把压力都转给数据库了   谢谢各位!

------解决方案--------------------
1.如果只是这样一句sql,写不写SP都一样。问题是不要一次把那么多数据取出来。
3.确实SP在数据库端完成。
分页参考
CREATE PROCEDURE sp_paging
(
@strTblName VARCHAR(100), --表名或视图表
@strFields VARCHAR(4000) = '* ', --欲选择字段列表
@strOrdField VARCHAR(100), --排序字段
@strKeyField VARCHAR(100), --主键
@intPageNo INT = 0, --页号,从0开始
@intPageSize INT = 10, --页尺寸
@strWhere VARCHAR(4000) = ' ', --条件
@bitOrdType BIT = 1 --排序,1=降序,0=升序
)
AS
SET NOCOUNT ON
DECLARE @strSQL VARCHAR(6000)

IF @intPageNo = 0
BEGIN
SET @strSQL = 'SELECT TOP ' + CAST(@intPageSize AS VARCHAR) + ' ' + @strFields + ' FROM ' + @strTblName
IF @strWhere != ' '
SET @strSQL = @strSQL + ' WHERE ' + @strWhere
IF @bitOrdType = 1
SET @strSQL = @strSQL + ' ORDER BY ' + @strOrdField + ' DESC '
ELSE
SET @strSQL = @strSQL + ' ORDER BY ' + @strOrdField + ' ASC '
END
