Combine column value from multiple table

Hi there,

 

I'm seeking your help on how we can creating a new column that combines value from multiple columns from different tables.

In particular, I have at least 2 tables, for example

 

Table 1:

Customer Name |    ID   |     DOB

A                        

B

C

Table 2:

Customer Name |    ID   |     Address

A

B

E

F

 

Expected result: I wanna have the list of unique Customer name from Table 1, Table 2 as well as other tables as below

Customer Name

A

B

C

E

F

 

Thank you for your help!

Hello @duycao 

You can create a calcualted table that give you the unique list from both tables like so.

 

Combined Table = 
DISTINCT(
    UNION(
        DISTINCT(Table1[Customer Name]),
        DISTINCT(Table2[Customer Name])
    )
)

 

 

You can continue to add the additional source tables in this one calculation.

 

Combined Table = 
DISTINCT(
    UNION(
        DISTINCT(Table1[Customer Name]),
        DISTINCT(Table2[Customer Name]),
        DISTINCT(Table3[Customer Name]),
        DISTINCT(Table4[Customer Name]),
        DISTINCT(Table5[Customer Name])
    )
)

The ID fields are the same in both tables? And I understand you want to do it in Power Query?
