comparing multiple values in two columns and displaying unique and matching values

Anonymous — Thu, 17 Oct 2019 15:16:39 GMT

Hey everyone,

I have two columns of ids that are from two different reports, I know for sure that there are more values in one column than the other but I want to know which are the Ids that aren't present in the other column and which ones are present.(I have thousands of these ids I want to compare, is there a query that can compare all the values one by one from both columns and match and provide an output)?

Data example:

Column1

905443
962910
963037
964534
964591
905463
964586
991158
964528
961843
961877
961869

Column2

994177
908419
908615
908395
908396
908402
908402
908402

Hi Anonymous

For the ones present in the first but not on the second column, create a new, one-column calculated table:

NewTable =
EXCEPT ( DISTINCT ( Table1[Coulmn1] ), DISTINCT ( Table2[Coulmn2] ) )

Hey thank you for your prompt response, I have already tried that but it shows "A table of multiple values was supplied where a single value was expected". Thoughts?

You've probably done something differently. Change the name of Column2 in table 2 to Column 1. Both columns in the expect should have the same name. From what I see there are no numbers in Table 2 present in Table1 in your example

See it all at work in the attached file.

The above post column 1 & column 2 were just sample data, I have column values mathcing other column values. I tried changing the names to same names but it did not work either.

Can one of the reason be that because lets say a value is in row 1 in column 1 and the value matching that value in column 2 is in row 223, could that be the reason? or does the formula check iteratively for all the values if they are matching or not?

AlB Thank you for the attached file, It worked, the only issue now is that I do not know if the unique values are from table 1 or table 2, hopefully that works when I sync the slicers from those tables.Thank you.

Kind Regards,

The unique values are from the first table in the EXCEPT( )

EXCEPT(Table1, Table2 ) gives you the values that are present in Table1 but not present in Table2. You can simply do

EXCEPT(Table2, Table1 ) if you want the values present in Table2 but not present in Table1
