Preparation of SQL predicates for physical storage scans.

Structs§

PreparedPredicate: One prepared predicate shared by index selection and scan construction. effective preserves the statement-level predicate for feedback and cache identity; residual is the exact executor-side remainder after pushdown.

build_alias_map_excluding: Build aliases that do not shadow real FROM columns. SQL WHERE binding must prefer a source column when an output alias has the same name.
prepare_bound_predicate: Prepare a predicate for paths whose SQL binding has already been resolved by their caller (temporal and certified narrow scans).
prepare_scan_predicate: Resolve SELECT aliases, simplify constants, substitute correlated outer values and split the result into storage and residual predicates.
substitute_aliases: Substitute already-bound SELECT aliases inside a predicate.
