Exploiting Statistics on Query Expressions for Optimization

Summary: Extends the optimizer to exploit statistics on intermediate query expressions (not just base-table stats), yielding better plan quality. Proposes a workload-driven feature selection to identify a small, impactful subset of expressions' statistics, with validation on SQL Server 2000. (summarized by gpt-5-nano on Feb 09 2026)
