Count the user_id's present in one table and are not present in the another table

[Anonymous]

I have two tables:

account_users and accounts_user_tags

connected with account_users.id = accounts_user_tags.user_id

Need a measure to calculate the extra id's present in account_users  table but are not present in accounts_user_tags

I tried something like: 

user_count = CALCULATE(
COUNT(
'public accounts_user'[id]
);
FILTER('public accounts_user_tags';'public accounts_user_tags'[user_id])
)

but, I guess it's not correct.

Anyone could guide me here.

Hi @Anonymous,

If I understand you correctly, the formula below should work in your scenario? 

user_count =
COUNTROWS (
    FILTER (
        'public accounts_user';
        CONTAINS (
            'public accounts_user_tags';
            'public accounts_user_tags'[user_id]; 'public accounts_user'[id]
        )
            = FALSE ()
    )
)
