<tt>Hi Guys!<br>
<br>
I need to make an UPDATE on a column reordering it with a sequence
using order by a description.<br>
Confusing??? Well.. Let me give an example...<br>
<br>
Today, my table it's organized like this:<br>
<br>
Code / Description<br>
9 Orange<br>
15 Apple<br>
1 Pear<br>
3 Tomato<br>
<br>
I wanna to reorganize (reordering the code from 1 to ... ordering by
description)<br>
</tt><tt><br>
Code / Description<br>
</tt><tt>1 Apple</tt><br>
<tt>2 Orange<br>
3 Pear<br>
4 Tomato</tt><br>
<tt><br>
I created a sequence but I am having no succes to use it because UPDATE
don't accept ORDER BY CLAUSE. The "ideal SQL" is UPDATE table SET code
= nextval('sequence') ORDER BY description <br>
<br>
I searched a lot on the NET without ant "tip" for my case. <br>
It's a very simple need but I am not able to solve it...<br>
<br>
Anyone knows how I can do it?<br>
<br>
Cheers,<br>
<br>
