DAX random sample
Is it possible to create a new table in DAX which is a random sample of rows from another table? I would have to be able to refresh the sample table.
Hi Christann
To create a random sample table with DAX, I would use RAND() as suggested above, and create a table with an expression like this:
Random Selection = VAR SampleSize = 10 VAR TableWithRand = ADDCOLUMNS ( OriginalTable, "Rand", RAND () ) RETURN TOPN ( SampleSize, TableWithRand, [Rand] )The Random Selection table will end up with an extra column Rand but you can remove that if needed.
It appears that the SAMPLE function returns a deterministic sample.

I think you are looking for RAND() function. Try to read more about it and it should solve your issue.
From what I have read, it looks like the RAND() function creates new random numbers. I am looking for a random sampling of rows in a table, to be created as a new table. Thanks though!
