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.

hops[0] is carried on the OrderClause itself (it becomes the clause’s parent/related linkage), so only hops[1..] are nested here — matching the shape the macro used to compute at expansion time.

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