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

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

## Re: comparing multiple values in two columns and displaying unique and matching values

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] ) )```

## Re: comparing multiple values in two columns and displaying unique and matching values

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

## Re: comparing multiple values in two columns and displaying unique and matching values

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?

## Re: comparing multiple values in two columns and displaying unique and matching values

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.

## Re: comparing multiple values in two columns and displaying unique and matching values

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( )
