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

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

Expand the table > Select the required column from Table B

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])Related article:
