Function order_value_sql 

pub fn order_value_sql(hops: &[RelationHop], column: &str) -> String

Build the correlated-subquery expression that yields column at the end of hops, relative to the table reached by the first hop.

Unscoped: this string ignores every hop’s RelatedReadScope and does not handle self-relation hops. It is only suitable for a backend that enforces no read policy (the embedded rusqlite renderer); the Postgres backend renders relation sorts from the hops themselves, applying each hop’s scope.

hops[0] is rendered by the caller (it becomes the outermost subquery’s linkage), so only hops[1..] are nested here.

Panics if hops is empty; callers only reach this from a generated accessor that has traversed at least one relation.
