<b>Subject:</b> [Info-ingres] One up unique number for an attribute - in SQL - does anyone know the trick of doing this?<o:p></o:p></span></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial","sans-serif"">in command line sql I am populating a new table - one of the columns is a sort order
</span><br>
<br>
<span style="font-size:10.0pt;font-family:"Arial","sans-serif"">each row of this field <b><u>must</u></b> be a 'one up' unique number starting at 1 and ending as the number of rows in the table </span>
<br>
<br>
<br>
<span style="font-size:10.0pt;font-family:"Arial","sans-serif"">I know that I could do this in OpenROAD , and in another guise this is done in OpenROAD, but in this case it has to be done in SQL or maybe in report writer.</span>
<br>
<br>
<span style="font-size:10.0pt;font-family:"Arial","sans-serif"">It does not matter which rows contain 1 ,2 etc although one of the columns does have a set of unique numbers with gaps which could be used to determine the order of row 1, 2 etc. </span>
<br>
<br>
<span style="font-size:10.0pt;font-family:"Arial","sans-serif"">Does anyone know of a 'trick' to do this?</span>
<br>
<br>
<span style="font-size:10.0pt;font-family:"Arial","sans-serif"">In mysql it is possible to define unique one up numbers when creating a table does modern Ingres have this feature?</span>
<br>
<br>
<span style="font-size:10.0pt;font-family:"Arial","sans-serif"">thanks </span><br>
