How to Join tables and Add column using DAX(Edit Query)

[Anonymous]

I have to join two tables A and B using ID.
Then add on column 'Degree' from table B to Table A
Expected O/P : Table contains column A,B & C

Input File:

Table A
ID	Name
111	Adex
222	belly
333	Caty

Table B
ID	Degree
111	B.Com
222	B.Tech
333	BCA

Expected Ouput :

Table A
ID	Name	Degree
111	Adex	B.Com
222	belly	B.Tech
333	Caty	BCA

Using DAX (Edit query/Transform Data)
Please help me out solving this and if possible please explain syntax to be used.


Thanks in Advance!

Providing you have a relationship, just add a column on Table A, the paste in the following 

Degree = RELATED('Table B'[Degree])

DAX way:

LOOKUPVALUE (when there is no relationship between tables)

Add a new column using following DAX

Degree = LOOKUPVALUE('Table B'[Degree],'Table B'[ID],'Table A'[ID])

RELATED (When the tables are related)

Degree 2 = RELATED('Table B'[Degree])

Hello @Anonymous

Power Query way: Merge Queries

With Table A selected > Home > Merge Queries:

Select Table B in the second table and select the common column (ID in this case):

Under Join Kind, select Left Outer. Click Ok

Expand the table > Select the required column from Table B

Click Ok.

Output:

What should we do if those tables have many to many relationships?
