帮忙修改存储过程的,实现排序,谢谢！

[fanqingfeng]

我有一个可用的存储过程，现需要帮忙改一下：
目前的数据结果排序是按照@FdOrder排序的
需求是希望按照@QueryStr 语句末尾的order by 进行排序

因为目前的代码 在@QueryStr 中可以 order by B0165M desc 但不能@FdOrder="B0165M desc "

set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
go

通用的存储过程，可以参考这个进行修改

[hanjs]

meinv!

ORDER BY '+@strID+' DESC')

这个最好还是前台传入 排序的信息

路过,学习,留记号.

[sybasebbs]

强，记一下。

[itymx]

学习 SQL 很深啊！！！

[sp4]

呵呵，这个自己漫漫调吧，代码多看得乱。不过分页代码都简单的很。自己看会长见识的。

大数据量用这个通用的分页程序效率不高

路过，表示关注

使用Print调试看看，即可查出问题所在，这样看有点晕哦
