<div class="moz-text-html" lang="x-western"><tt>Hi Guys!<br /><br /> I need to make an UPDATE on a column reordering it witha sequence using order by a description.<br /> Confusing??? Well.. Let me give an example...<br /><br /> Today, my tableit'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 touse it because UPDATE don't accept ORDER BY CLAUSE. The "ideal SQL" is UPDATE table SET code = nextval('sequence') ORDERBY description <br /><br /> I searched a lot on the NET without ant "tip" for my case. <br /> It's a very simple needbut I am not able to solve it...<br /><br /> Anyone knows how I can do it?<br /><br /> Cheers,<br /><br /> -- <br />Rodrigo Carvalhaes<br /><br /></tt></div><br />-- <br />Esta mensagem foi verificada pelo sistema de antivírus e <br />acredita-se estar livre de perigo.
