Fuzzy matching required for exact match

[Anonymous]

Hi

I have 2 tables. Table A has a relationship with Table B using an ID in the standard way.

Lets' say both have 150 rows and it's a 1:1 relationship.

When I do a direct query in SQL 

SELECT *

  FROM [dbo].[A]

LEFT JOIN [dbo].[B] ON B.Id = A.BsID

I get the results expected: 150 rows

When I do merge queries in powerbi... I only get a match of 125 out of 150. I check fuzzy match and I get 150. 

What is PQ reading to differentiate my data that an SQL query directly on the DB does not? Or is this just an issue with the preview?

could you, at least, upload the id's involved?

Here is a nice article on Fuzzy Matching in Power BI and Power Query .
