Merge 2 tables into one table

Hi all, 

 

I have 2 different datasets uploaded in Power Bi as 2 different tables. These 2 tables are quite different but the unique identifier is the email address. However sometimes a contact is in one table but not in the other. What i would like to get is to merge the 2 tables into 1 and get all the fields from both tables.

 

There is an example below and the desired outcome.

 

Is this something possible in Power Bi?

 

 

Thanks,

Ale

  • Hi Alessandro-laba 

    You can create a new pbix file with these two tables(Merge and NATURALLEFTOUTERJOIN don't support tables from Power BI datasets) and try these steps.

     

    1 Remove ‘company’ column of Table 2 in Power Query

     

    2 Rename the ‘email address’ column of Table 1(NATURALLEFTOUTERJOIN doesn’t support Duplicate column names used for join)

     

    3 Create a Calculated table with NATURALLEFTOUTERJOIN function

    Table =
    
    VAR join_table =
    
        NATURALLEFTOUTERJOIN ( Table2, Table1 )
    
    RETURN
    
        SELECTCOLUMNS (
    
            join_table,
    
            "first name", [first name],
    
            "last name", [last name],
    
            "company", [company],
    
            "Name", [Name],
    
            "country", [country],
    
            "email address", [email address]
    
        )

     

    The result looks like this:

     

    For more details, you can refer the attached pbix file.

    In Power Query you can use Merge Queries option to get this result

    First Add these two tables to Power Query .

    Using the similar column , Merge the tables and expand to the result
