Only test with sum, count_distinct.

Is the fix already implemented in 2.18.14? I am having this issue too, the right values on preview and in fields, but not working with virtual fields.
The fix is only implementend on master. Not sure it will be on 2.18.
Ah, OK thanks for the info. Luckily I got around the problem by using a OGR virtual file.

I've just come across this problem in 2.18.18. When you say it's been implemented on the master, does this mean that, for me, the only way to get this problem fixed is to move to 3.0, or this there some patch I could apply?
