This is a distinct list of CallLogID which is always 1. What dimension are you counting this CallLogID on? In the sample you have provided there is only one field, but I am guessing that you might have more dimension in your actual scenario.
We sort of understand what you want, but what is still unclear is that what dimension are you counting CallLogID on? In other words, when you say Count(CallLogID) as expression, what is your dimension?
