Combining same field from 3 tables into single list

[matdune56]

Hi

I hae queries which brings in company information for 3 different sources.

Each of the resulting tables has a Company Name Column

What I want to do is produce a single list of distinct companies from combining the 3 tables

e.g

table1- field company Name

Company1

Company2

table2- field company Name

Company3

Company4

table3- field company Name

Company5

Company6

Resulting table - field company Name

Company1

Company2

Company3

Company4

Company5

Company6

thanks

Mat

Hi Mat,

Maybe the Distinct function is also needed.

NewTable =
DISTINCT (
    UNION (
        VALUES ( Table1[Company Name] ),
        VALUES ( Table2[Company Name] ),
        VALUES ( Table3[Company Name] )
    )
)

Best Regards,

[matdune56]

thank you both for such a quick reply. Works perfectly.

Used a DAX function in the end

sorry, one last question.

How would I add a field that denotes which table(s), the company name came from. Is it possible.

really apprecaite your help on this.

What if it comes from more than one table?

Hi

the table that's been created has a single field, with all (distinct) company names from each of the 3 tables.

By looking at this new table, I'd want to user to know whether it had come from Table 1, Table 2, Table 3 or a combination of the 3 (the company name could be in more than one table).

Hi @matdune56

I think this would best done in the query editor but if you want to do it in DAX you can create a calculated table with this code:

NewTable =
UNION (
    VALUES ( Table1[Company Name] ),
    VALUES ( Table2[Company Name] ),
    VALUES ( Table3[Company Name] )
)
