When using the Data Profile function on the Person.Person table in the AdventureWorks2014 database I see strange results for the highest and lowest occurence in the LastName field: Diaz is the highest and Billstrom is the lowest. In reality Abbas is the lowest when sorting by LastName ASC where count(*) == 1

 

I am not entirely sure that 'Highest occurence’ is clear to everyone that is not a natvie speaker: you could also assume this should be the highest sorted value.

Hi @rory.smith, In the Data Profile feature highest and lowest occurrence is indicating which value in a given field occurs the most, and which occurs the least. In SQL this would look like:

SELECT CLastName], Count(nLastName])
FROM OMDW].WPerson]
GROUP BY BLastName]
ORDER BY Count(nLastName]) DESC

In my version of AdventureWorks, the Person table results in Diaz occurring the most at 211 times. 

If you reverse the Order By ASC, I get Barlow, then Billstrom preceding 687 other names that only occur once.  Beyond the count, I don’t believe there is any additional sorting happening, so the 687 single occurrences may appear in a different order. 

 

Using this logic, it seems to be working as expected.
