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!!!!

Am I right that this clause is embedded in a SQL statement like

where <table> has columns UNIQUE_ROW_IDENTIFIER and MY_CODE ?

Yes, precisely. :)
