Sql 根据案例条件获取不同的计数

我有一个问题，我无法在一个查询中解决。我想找到所有满足policy='disable'的不同用户标识，并将它们乘以9。可以在一个查询中完成吗？我很难找到这样一个问题

txn_week,
SUM(CASE WHEN policy = 'disable' AND COUNT(DISTINCT user_id) THEN 9 ELSE 0 END) as disabled_accounts
from table
group by txn_week

我想你想要：

     count(distinct CASE WHEN policy = 'disable' then user_id end) *9 as disabled_accounts
from table
group by txn_week;
