PowerPivot从Access中获取排除的数据

Question

Sample Data

I have a Access, which has more than 1 million rows of data, as you can see from the screenshot. I want to dedupe the data in term of BRUIDREQID, as it has duplicates. Is there any way that when I connect data from Access to PowerPivot, I can get deduped dataset?

What I am doing now is using Python to dedupe the data and extract it as a csv file. I want to know whether I can use PowerPivot instead and save more time to dedupe large data set.

When accessing the Access database, you should be able to write arbitrary SQL, and you could just do a

SELECT DISTINCT 
* 
FROM Table

, which would de-dupe the table.

Power Pivot does not offer any functionality to change the existing data in a table once imported - you cannot add or remove rows, nor can you alter the values of any imported fields.
