Compare one to many column values between two tables

Hello,

 

I have a Students table that lists each UserID value once.

I want to know in a new column in the Students table if the UserID field has any matching values in the Infractions table.

It can either be the UserID value or a 1 for a match or a 0 for a non-match.

In the Infractions table, there can be many rows or no rows at all that match the UserID field from the Student table.

Thank you for posting the data.

If you want to create a calculated column in the Students table, the existing relationship makes things reasonably straightforward.

 

NewCol = CALCULATE(COUNT(Infractions[Infraction]))

 
That will give you the count for each student. If you want a 1 or 0 you just edit the formula using an IF statement.

Let me know if that helps.
