How can I use a sub query in an update statement ? Contrived Example:
Copy code
UPDATE Users SET active=false WHERE id IN (SELECT user_id FROM deactivated)
It seems the only option I have is 
inList
but I am afraid if I call 
map{..}/toList()
on my subquery it would materialize those results.

It’s better to update it like this:
Copy code
Users.innerjoin(Deactivated).update {
    it[Users.active] = false 
}
But if you want to use subquery than:
Copy code
val subquery = wrapAsExpression<List<EntityId<Int>>(Deactivated.slice(Deactivated.userId).selectAll())
Users.update( where = {
Users.id inList subquery}) {
   it[Users.active] = false 
}
