Hi @demfabris thank you!

Would love to have you involved with the project, and contributing!

This issue is actually almost completed (bcaea75). The only issue at the moment is that if you change the NS/DB using it is not reflected...

-- These will use the configured NS / DB when connecting...
SELECT * FROM $session.ns;
SELECT * FROM $session.db;
SELECT * FROM session::ns();
SELECT * FROM session::db();
-- If you then change to another NS / DB...
USE NS test DB test;
-- Then the change is not yet reflected in these functions...
SELECT * FROM $session.ns;
SELECT * FROM $session.db;
SELECT * FROM session::ns();
SELECT * FROM session::db();

@demfabris the code where this happens is ...

surrealdb/lib/src/dbs/executor.rs

Lines 181 to 210 in 28f66f4

Statement::Use(stm) => {
if let Some(ref ns) = stm.ns {
match &*opt.auth {
Auth::No => opt.ns = Some(Arc::new(ns.to_owned())),
Auth::Kv => opt.ns = Some(Arc::new(ns.to_owned())),
Auth::Ns(v) if v == ns => opt.ns = Some(Arc::new(ns.to_owned())),
_ => {
opt.ns = None;
return Err(Error::NsNotAllowed {
ns: ns.to_owned(),
});
}
}
}
if let Some(ref db) = stm.db {
match &*opt.auth {
Auth::No => opt.db = Some(Arc::new(db.to_owned())),
Auth::Kv => opt.db = Some(Arc::new(db.to_owned())),
Auth::Ns(_) => opt.db = Some(Arc::new(db.to_owned())),
Auth::Db(_, v) if v == db => opt.db = Some(Arc::new(db.to_owned())),
_ => {
opt.db = None;
return Err(Error::DbNotAllowed {
db: db.to_owned(),
});
}
}
}
Ok(Value::None)
}

It should be relatively easy to change the NS/DB stored in the $session context here too, but I'm just thinking whether there is a better way of going about this...
