Filter based on join data

Hi, would it be possible to query a list of student and filter by the name of its coach. The data is <student>.coach.fullname where coach is added as a with join. I would like to get every student that have a certain coach.

Fiddling around in drizzle studio demo I managed to do something like that:

  db.select().from(orders).fullJoin(customers, eq(orders.customerId, customers.id)).where(eq(customers.contactTitle, "Owner"))

  db.select().from(orders).fullJoin(customers, eq(orders.customerId, customers.id)).where(eq(customers.contactTitle, "Owner"))

But I couldn't find a way to do it with query builder

In the docs https://orm.drizzle.team/docs/rqb#select-filters there is a where inside of the query but when I try it this option doesn't exist

This option was removed from drizzle due to the complexity of the resulting query But you can achieve the result you want with a subquery Can you put the query you want in drizzle.run so I can take a look?

Describe what you want Filtering by nested relations is a common thing to do and was recently removed to improve performance. I propose a syntax to add this feature back into the relational queries...
