Hi all, I&#39;m trying to run a simple standard deviation function on a column using MonetDB --<br><br><br>select stdev( columnname ) from tablename<br><br><br>-- is this possible with the current release?  The only posts I can find about stdev() or variance() are quite old, such as<br>

<br>a 2008 post requesting medians (which has been implemented) and quantiles (which I cannot find?)<br><br><a href="http://osdir.com/ml/db.monetdb.bugs/2008-06/msg00206.html">http://osdir.com/ml/db.monetdb.bugs/2008-06/msg00206.html</a><br>

<br>a 2010 post offering to add these functions to the main release code.<br><br><a href="http://mail.monetdb.org/pipermail/users-list/2010-January/003836.html">http://mail.monetdb.org/pipermail/users-list/2010-January/003836.html</a><br>

<br><br>What would be the easiest way to get MonetDB to produce standard deviations, variances, and quantiles (let&#39;s say the 25th percentile)?<br><br>From the discussion list, it looks like people have succeeded in doing it, but they&#39;re probably much more advanced users than I am.  ;)<br>

<br><br>Thanks!!!<br>
