I have above structure.

Description : Server entity have three attributes.
Name - Type
localId - UUID
serverId - UUID
SyncFlag - Int16.

SyncFlag have three possible values. [1,2,3]. 1 for insert, 2 for update and 3 for delete.

Now, requirement is that, Want to fetch one employee with related projects using employee serverId. But not want that projects which project status is deleted.

Any help appreciated :)

Thank you.

If I understood you correctly, I think it's something like this:

let serverId = // ...
let employee = dataStack.fetchAll(
    From<Employee>()
        .where((\.sync ~ \.serverId).any() == serverId)
)
