create new column from 2 tables using if function

[gerard-kouadio]

Hello, I have 2 tables and I want to create a column from the ids of the 2 tables. I want to do something like this:

if id of table 1 = id of table 2, put yes, if no, put No.

NB: there is a many-to-many relationship in the tables

Thank you for your help !

HI  @gerard-kouadio ,

Pls refer the below sample:

tableA:

Table B:

Column = 
var Q1 = TableA[ID]
var NewCol = CALCULATE(MAX('Tableb'[ID]),Tableb[ID]=Q1)
return IF(NewCol<>BLANK(),1,BLANK())

I finally used this code:

New colomn = if(ISBLANK(LOOKUPVALUE('Table1'[Id], 'Table1'[Id],Table2[Id])),"Non","Oui")

Hi,

This could also work:

Column =
VAR _Lookup = [Product]
RETURN
IF (
ISBLANK ( LOOKUPVALUE ( Table2[Product], Table2[Product], _Lookup ) ),
"No",
"Yes"
)

Hi,

Measure=IF(SELECTEDVALUE(TAble1 [ID])=SELECTEDVALUE(TAble2 [ID]),"YES","NO")

Thanks,

Hi @gerard-kouadio,

Can you please show a picture of the data model as well as explain how you want to visualize it? Which visual do you want to use and which columns do you also want to put into the visual?

Best regards

Hi,

I think you can achive this by using methods explained in this article:

https://www.sqlbi.com/articles/from-sql-to-dax-joining-tables/

Without knowing your data or model I think you should look at the selectcolumns and natural join, treatas and/or lookup.

And at the end combine this with IF or maybe switch.
