Abstract
A relational data base management system includes a query processor that permits consideration of alternative user-specified access paths, which the processor will validate and incorporate into the query execution plan it otherwise generates. The optimizer of the query processor retrieves user-specified data that defines an access path for a query during bind operations. Any access path parameters that are invalid are replaced with processor-selected values.
