Hi,

I am trying to count unique values in the field (using SQL Select) if the value is greater than 0

So, here is syntax I use (simplified) (which generates an error):
select count( case when mytable.myfield = 0 then 0 else distinct( mytable.myfield ) end ) as TotCount
What is wrong in the above syntax?

TIA
