存储过程里怎么用order by 不同的条件。

[luancode]

前面跟一个参数过来，用户选择的@orderby int
假设orderby的值为1，执行order by price1 desc
orderby值为2时，执行order by price1 asc
orderby 值为空时，即用户不选择条件排序，那么order by id desc

CREATE procedure ProList
@myname varchar(100),
@orderby int
as
select id,myname,price from [pro]
where online=1
and myname like '%'+@myname+'%'

这儿排序怎么写

GO

[Lori268]

CREATE procedure ProList 
@orderby int 
as 
begin
select top 10 id,type,subject from [table1]   order by   case @orderby when 1 then  id  when  2  then  type   end desc
end

[Lori268]

自己动手改自己的吧

[luancode]

我不是根据不同的字段排序，是两种情况都有，当orderby不为空时，根据同一字段price升序或降序，当orderby为空时，根据另一字段id desc

[mugua604]

CREATE procedure ProList 
@orderby int 
as 
begin
select top 10 id,type,subject from [table1]   order by   case @orderby when 1 then  id  when  2  then  type   end desc
end

CREATE procedure ProList
@myname varchar(100),
@orderby int
as
select id,myname,price from [pro]
where online=1
and myname like '%'+@myname+'%'

--这儿排序怎么写
order by case when @orderby is null then id else price1 end desc

GO

还有一种情况，price1升序怎么排呢？一共有三种.
orderby的值为1，执行order by price1 desc
orderby值为2时，执行order by price1 asc
orderby 值为空时，即用户不选择条件排序，那么order by id desc

CREATE procedure ProList 
      @myname varchar(100), 
      @orderby int 
as 
    declare @s varchar(5000)
    set @s='select id,myname,price from [pro] where online=1 and myname like '''+ '%'+@myname+'%''' 
    if @orderby=1
        exec(@s+'  order by price1 desc')
    else if @orderby=2
        exec(@s+ ' order by price1 asc')
    else 
        exec (@s+'order by id desc')

CREATE procedure ProList 
      @myname varchar(100), 
      @orderby int 
as 
begin
    if @orderby=1
		select id,myname,price from [pro] 
		where online=1 
			and myname like '%'+@myname+'%' 
		order by price1 desc        
    else if @orderby=2
        select id,myname,price from [pro] 
		where online=1 
			and myname like '%'+@myname+'%' 
		order by price1 
    else
		select id,myname,price from [pro] 
		where online=1 
			and myname like '%'+@myname+'%' 
		order by id desc  
end
go

[luancode]

CREATE procedure ProList
@bid varchar(20),
@sid varchar(20),
@myname varchar(100),
@myitem varchar(100),
@price_1 int,
@price_2 int,
@commend int,
@orderby int
as
declare @s varchar(5000)
set @s='select id,myname,img,price1,commend,online,hit,addtime,kucun from [pro]
where online=1
and ('','')+bid like '+'%,'+@bid+'%''
and ('','')+sid like '+'%,'+@sid+'%''
and myname like '+'%'+@myname+'%''
and myitem like '+'%'+@myitem+'%''
and price1>=(case @price_1 when 0 then price1 else @price_1 end)
and price2<=(case @price_2 when 0 then price2 else @price_2 end)
and commend=@commend'
if @orderby=1
exec(@s+' order by price1 desc')
else if @orderby=2
exec(@s+ ' order by price1 asc')
else
exec (@s+'order by id desc')

这是我的全部代码。
这样写后，提示：不允许对具有不止一条 SELECT 语句的远程存储过程或存储过程使用服务器游标。请使用默认结果集或客户端游标。我在分页那儿调用：set rs=cmd.execute 这行提示错误。
dobear_0922，你那样写，我的代码是不是会很多？

這個問題應該不是存儲過程的
你先在查詢分析器調試看看~~

[luancode]

CREATE procedure ProList
@bid varchar(20),
@sid varchar(20),
@myname varchar(100),
@myitem varchar(100),
@price_1 int,
@price_2 int,
@commend int,
@orderby int
as
select id,myname,img,price1,commend,online,hit,addtime,kucun from [pro]
where online=1
and (',')+bid like '%,'+@bid+'%'
and (',')+sid like '%,'+@sid+'%'
and myname like '%'+@myname+'%'
and myitem like '%'+@myitem+'%'
and price1>=(case @price_1 when 0 then price1 else @price_1 end)
and price2<=(case @price_2 when 0 then price2 else @price_2 end)
and commend=@commend
order by (case @orderby when 1 then price1 when 2 then id else addtime end) desc
GO

这样执行正确的，可是达不到我想要的效果，price asc.哎

把你的做成動態不可以嗎
Print @S
看看有沒有語法錯誤
