Abstract
A method, a system, and a computer program product for executing a query in a database system. A query plan for execution of a query is generated. The query requires access to at least one table stored in a database system. One or more occurrences of one or more duplicate predicates is detected in the query plan. In response to detecting a first occurrence of the duplicate predicates, one or more intermediate query execution results responsive to the duplicate predicates are generated. The generated intermediate query execution results are cached. Query execution results incorporating cached intermediate query execution results being responsive to each occurrence of the duplicate predicates subsequent to the first occurrence of the duplicate predicates in the query plan are generated.
