Re: All tested on the same column, some functions work, some don't?

24 Apr 2013

      I'm sorry for the flood of e-mails.

When I add a DISTINCT to the creation clause..

 count( distinct case when gear in ( 3 , 4 ) then mpg end )*1

..then median() and prod() break as well!  Here is the EXPLAIN and TRACE
output.  Sorry, I should've tried this on fake data sooner!

Now that I know I can re-create this error with public data, should I file
a bug report?  Thanks!!!!

I wrote an R script (for Windows) that created some dummy data and
reproduced *three* of the five errors.  median and prod still do not work
in my confidential data.  sign, stddev, and stddev_pop do not work when
using the R script pasted below.  I created this the same way as before:
create table mtcars2 as select carb , count( case when gear in ( 3 , 4 )
then mpg end ) as gears from mtcars group by carb with data;
The starting data set I used is the `mtcars` data.frame that you can view
if you open up R and type `mtcars`..  but I've pasted it below so you can
see it's nothing special.
Here's the three EXPLAIN commands (run in mclient)..  below that, I've
pasted R code to precisely re-create the database as I have it on my
computer.   :)
When I add a *1 on the end of the count( case when gear in ( 3 , 4 ) then
mpg end )*1 clause, I get the same errors..
Thanks!!!!
