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

[Anonymous]

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?

[AlB]

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.

@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

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?
